Cita-cita ke-7, ku ingin bisa memperbaiki busi motorku

Sugoi Ghito!!!!!!!!



Cara Memperbaiki Mobil atau motor yang terendam air


Bila mobil atau motor anda terendam air akibat banjir atau terperosok dalam
sungai sehingga air masuk
kedalam mesin, kini ada solusi yang murah tanpa perlu membongkar mesin.
Untuk Motor Bensin 4 tak
Langkah I: Lepaskan filter udara dari sarangannya dan keringkan dengan lap.
Langkah II: Keringkan koil dan distributor serta kabel busi dari air
Langkah III: Kuras oli mesin sampai habis dan bersihkan filter oli.
Langkah IV: Isi mesin dengan " Oli spesial yang larut dengan air" yaituShell
Dromus B , Esso Kutwell 30,
40,45 atau 50 , Mobilmet 122/110. atau TOTAL Lactuca LT2 Bila isi oli normal
0.9 ltr anda harus mengisi
oli satu liter
Langkah V: Gerakkan mesin dengan starter kaki tanpa dikontak sekitar 30 kali

(posisi katup bensin tertutup)

Langkah VI: Kuras oli pelarut tersebut sampai habis dan perhatikan warnanya

bila oli tersebut berwarna

putih susu menandakan ada air yang dilarutkannya dan tunggu sekitar satu jam

agar semua cairan oli pelarut

terkuras habis.

Langkah VII: Isi mesin dengan Peratamina ENDURO atau Mesarn Super 20W50

Setelah isi oli cukup hidupkan mesin dan jalankan mesin sampai 1 jam agar

mesin cukup panas. Setelah itu

kuras kembali oli dari dalam mesin dan pastikan sudah tidak ada air dalam

oli dan pada filter oli.

Langkah VIII: Isi dengan oli Enduro atau Mesran Super 20W/50 dan jalankan

mesin seperti biasa.


Untuk Motor Bensin 2 tak

Langkah I dan II sama dengan mesin bensin 4 tak.

Langkah III: buka busi dari lubangnya dan semprotkan oli spesial yang larut

dengan air" yaitu Esso Kutwell

30, 40,45 atau 50 , Mobilmet 122/110 atau TOTAL Lactuca LT2. dengan sprayer

agar dapat menjangkau

silinder dan kruk as.

Langkah IV: Gerakkan mesin dengan starter kaki tanpa dikontak dan posisi

katup bensin tertutup sekitar 30

kali agar oli pelarut dapat bekerja melarutkan air yang ada dalam mesin,

setelah itu pasang busi dan

hidupkan mesin dengan oli samping Pertamina 2T Enviro atau 2T Sport TCA

sekitar 5 menit dan mesin dapat

berjalan normal kembali.


Bila air masuk ketangki bensin motor, dibawah tangki biasanya ada katup

pengunci bensin , bukalah baut pada

katup itu dan keluarkan air dari dalam tangki sampai habis


Untuk Mobil Bensin dan Diesel

Langkah I : Periksa filter udara apakah kondisinya basah atau kering, bila

kering berarti air yang masuk

kedalam mesin relatif lebih sedikit daripada bila basah.

Langkah II: Lepaskan filter udara dan sarangannya dan keringkan dengan lap.

Langkah III: Keringkan koil dan distributor serta kabel busi dari air

Langkah IV: Kuras oli mesin sampai habis dan lepaskan filter oli, bila ada

air dalam oli yang dikuras dan

pada filter oli yang dilepas ,berarti banyak air yang masuk kedalam mesin

yang harus dikeluarkan.

Selanjutnya tutup lubang filter oli dengan baut penutupnya dan seal kantong

plastik agar tidak bocor

atau rembes bila mesin diisi oli pelarut air yang sangat encer.

Langkah V :Tiup dengan angin melalui lubang pengisian oli agar semua oli dan

air yang ada dapat keluar dari mesin.

Langkah VI : Buka "rocker cover" mesin anda dan bersihkan dan keringkan air

yang ada disitu.

Langkah VII : Isi mesin dengan " Oli spesial yang larut dengan air" yaitu

Shell Dromus B , Esso Kutwell

30, 40,45 atau 50 , Mobilmet 122/110. atau TOTAL Lactuca LT2 Bila isi oli

normal 3 liter anda harus

mengisi oli pelarut sekitar 3,5 liter dengan cara menuang melalui klep atau

camshaft mesin secara merata

agar air yang terperangkap disana dapat larut oleh oli. Dan biarkan kondisi

ini selama 2 jam , setelah

itu gerakkan mesin agar berputar dengan cara sedikit didorong dalam kondisi

masuk gigi 2 atau langsung

distart, tetapi kabel koilnya dilepas, agar mesin tidak hidup tetapi hanya

berputar sedikit saja supaya

air yang terperangkap disitu dapat keluar dan bercampur dengan oli pelarut..

Langkah VII: Kuras oli pelarut tersebut sampai habis dan perhatikan warnanya

bila oli tersebut berwarna

putih susu menandakan banyak air yang dilarutkannya, bila warnanya keruh

berarti sedikit saja air yang

larut dan tunggu sekitar satu jam agar semua cairan oli pelarut terkuras

habis.

Langkah IX: Pasang filter oli yang baru dan Isi mesin dengan Pertamina Prina

XP 20W50 Fastron 20W50 10W/40

dan Mesran Super untuk mesin bensin dan Pertamina Meditran SC 15W/40 ,

Meditran SX 15W40 atau Meditran S

40 untuk mesin diesel. Setelah isi oli cukup hidupkan mesin dan jalankan

mesin ssekitar 1 jam agar mesin

cukup panas. Setelah itu kuras kembali oli dari dalam mesin dan pastikan

sudah tidak ada air dan buka filter

oli dan periksa apa ada air disitu, bila masih ada air yang terlihat

gantilah filter oli itu dengan yang

baru, setelah ini barulah mesin bebas dari air yang masuk kedalam mesin.

Langkah X : Bila tangki bahan bakar kemasukan air, prinsipnya bahan bakar

bensin dan solar mempunyai

berat jenis lebih kecil dari air ,jadi bila air masuk maka bahan bakar ada

diatas .kalau cukup banyak dapat

dikeluarkan menggunakan slang kecil yang dimasukkan ketangki sampai kedasar

dan disedot maka air akan

keluar melalui selang kecil tersebut sampai habis. Bagi mesin bensin dapat

mengeluarkan air yang tersisa

dari saluran filter bensin sebelum masuk kepompa injektor hisaplah air dari

situ sampai selesai , atau

membuka baut untuk mengeluarkan bensin dari floater dikarburator alirkan

sampai air habis.

Bagi mesin diesel lakukan pemompaan melalui pompa tangan ditempat biasanya

mengeluarkan busa dari tangki

solar dan lakukan pemompaan sampai air habis


Langkah XI : Isi mesin dengan oli pada langkah IX dan jalankanlah

sebagaimana biasa

Toshihide Maskawa
“Akhir yang manis dari penantian panjang”, ungkap penulis ketika mengetahui nama-nama penerima nobel fisika 2008. Betapa tidak, tahun 1998 sebelum meninggalkan almamaternya L.T. Handoko sejawat penulis di Universitas Hiroshima bercerita bahwa komunitas fisika teori Jepang berharap Kobayashi dan Maskawa mendapat nobel fisika. Sebenarnya, tidak ada ahli fisika di dunia yang bekerja dengan misi khusus mendapat nobel, tidak terkecuali Yoichiro Nambu, Makoto Kobayashi dan Toshihide Maskawa. Mereka bekerja karena mencintai pekerjaannya, mencintai ilmu. Tetapi dalam perkembangannya ada alasan yang membuat komunitas fisika teori Jepang berharap nobel bagi sejawat senegara mereka.

Nobel fisika 2008 berbeda dari nobel fisika 1979 yang juga diberikan kepada tiga ahli fisika teori yaitu Abdus Salam, Sheldon Glashow dan Steven Weinberg. Ketiga fisikawan ini berasal dari negara berbeda, Salam dari Pakistan dan tinggal di Itali sedangkan dua lainnya dari Amerika tetapi mendapatkan nobel fisika untuk satu teori yang sama yaitu teori unifikasi gaya elektrolemah. Teori ini sekarang sering disebut sebagai teori Glashow-Salam-Weinberg.

Sebaliknya Nambu, Kobayashi dan Maskawa berasal dari satu negara tetapi mendapatkan nobel untuk dua teori berbeda. Nambu yang kelahiran Tokyo 1921 dan mendapatkan gelar dotornya di Universitas Tokyo tahun 1952 serta menjadi profesor di Universitas Chicago sejak 1958 dianugerahi nobel karena gagasan perusakan simetri spontannya (sponatenous symmetry breaking, SSB) dalam model sigma.

Gagasan ini dimuat dalam prosiding konferensi internasional kesepuluh fisika energi tinggi di Jenewa tahun 1960. Satu tahun kemudian Jeffrey Goldstone dari Amerika menulis generalisasi SSB untuk fermion di jurnal Nuovo Cimento. Hasil sampingnya berupa boson tak bermassa. Di buku-buku teks SSB kadang diidentifikasi dengan dua nama Nambu-Goldstone tetapi lebih sering hanya satu nama yaitu Goldstone dengan sebutan teorema Goldstone.

Gagasan Goldstone disempurnakan Peter Higgs tahun 1964 dengan mekanisme pembangkitan massa Higgs yang terkenal dalam fisika partikel modern. Mekanisme terakhir ini memberi bonus partikel Higgs yang menjadi perburuan di eksperimen terbesar dalam sejarah umat manusia Large Hadron Collider (LHC) di CERN Jenewa. Dengan demikian, jika SSB mendapatkan nobel maka yang seharusnya menerima adalah trio Nambu, Goldstone dan Higgs.

Kobayashi dan Maskawa (KM) mendapatkan penghargaan karena ide mereka yang dipublikasi di jurnal Progress of Theoretical Physics tahun 1973 dengan judul CP violation in the renormalizable theory of weak interaction. KM mengintrodusir matriks bauran dimensi tiga yang memuat dua hal baru. Pertama, kuark generasi ketiga bottom dan top, kedua, fasa CP (charge conjugation dan parity). Fasa dan simpangan CP merupakan salah satu syarat terjadinya alam semesta saat ini yang asimetri dari kondisi awal simetri.

Konfirmasi kuark top di CDF Fermilab tahun 1998 membangkitkan harapan nobel bagi KM. Konfirmasi simpangan CP melalui B-factory di akselerator linier Stanford (SLAC-B) dan Belle di pusat riset fisika energi tinggi (KEK) Tsukuba tahun 2001 meneguhkan harapan ini.

Tahun 1963, Nicola Cabibbo dari Itali menulis matriks bauran dua dimensi di Physical Review Letter (PRL). Dengan demikian, matriks KM dapat dipandang sebagai perluasan dari matriks Cabibbo sehingga sampai sekarang matriks ini disebut matriks CKM (Cabibbo-Kobayashi-Maskawa). Karenanya, nobel mestinya tidak hanya diberikan kepada KM melainkan juga Cabibbo.

Nobel fisika tahun ini juga menyisakan sisi lain yang menarik bagi orang Indonesia. Setelah peraih nobel fisika 2008 diumumkan, ahli fisika teori L.T. Handoko mendapat email dengan bunyi, ”Thank you for the works contributed to the establishing the theory...” dari para koleganya di Jepang. Handoko memang mempunyai hubungan personal yang kuat khususnya dengan Kobayashi sebagai host-profesor ketika berada di KEK Tsukuba antara tahun 1996-1997.

Ungkapan terimakasih tersebut terkait dengan riset Handoko dan koleganya dari Jepang, Jerman, Korsel dan Kanada pada kurun 1995-2002 yang mengkaji perusakan simetri global pada materi nuklir meson B. Kuark b berada di alam dalam bentuk materi nuklir meson B. Karenanya eksperimen untuk membuktikan teori ini selalu melibatkan meson B dan peluruhannya. Kalkulasi teori terkait dengan aneka mode peluruhan dan hasil akhirnya ini banyak dilakukan oleh Handoko pada era tersebut.

Dilain pihak, ada beberapa ilmuwan Indonesia yang turut berperan pada proses pembuktian eksperimental yang menjadi kunci penentu anugerah nobel untuk KM. Pada eksperimen pencarian kuark top misalnya, salah seorang anggota kolaborasi D-zero (D0) adalah van de Brink mahasiswa Indonesia alumni jurusan fisika UI.

Eksperimen yang lebih penting dan merupakan kunci utama konfirmasi kebenaran teori KM adalah B-factory. Selama ini ada dua fasilitas eksperimen utama yang bersaing ketat yaitu eksperimen BaBar di SLAC Stanford dan Belle di KEK Tsukuba. Di dalam kolaborasi BaBar terdapat dua ilmuwan Indonesia, Romulus Godang dan Rahmat.

Romulus yang asisten profesor di Universitas South Alabama dan alumni jurusan fisika USU bergabung sejak awal dimulainya kolaborasi BaBar sampai sekarang. Rahmat yang menyelesaikan program doktoralnya di University of Oregon melanjutkan program post-doctoral di Universitas Mississippi juga masih aktif di eksperimen BaBar. Demikian pula Haryo Sumowidagdo, alumni jurusan fisika UI, sampai saat ini masih bergabung di eksperimen D0.

Maskawa barangkali sosok yang paling unik dari trio peraih nobel fisika tahun ini. Penulis pernah dua kali bertemu Profesor Maskawa, tahun 1999 di universitas Hiroshima dan tahun 2001 di Yukawa Institue for Theoretical Physics (YITP) universitas Kyoto institusi tempat Maskawa. Ada hal yang tidak dapat penulis lupakan dari kedua pertemuan tersebut.

Ketika di universitas Hiroshima seorang teman membisiki penulis bahwa Maskawa tidak dapat berbicara dalam bahasa Inggris sehingga bila mau bicara dengannya harus dengan bahasa Jepang. Hal yang sama juga terjadi ketika di YITP, host-profesor penulis di sana berbisik sama. ”Shinjirarenai (tidak dapat dipercaya)”, demikian reaksi dalam hati ketika dibisiki untuk pertama kalinya.

Dari kisah di depan, ada dua pelajaran yang dapat diambil oleh fisikawan dan ilmuwan Indonesia umumnya. Pertama, gagasan Nambu maupun KM yang akhirnya mendapatkan nobel dimuat di prosiding dan jurnal dengan impact factor atau peringkat tidak tinggi. Reputasi ilmuwan secara umum ditentukan oleh jumlah publikasi dan peringkat jurnalnya. Hitoshi Murayama dari University of California Berkeley dan Ernest Ma dari University of California Riverside, misalnya, selalu berusaha menulis tema terdepan dan mempublikasikannya di PRL yang ber-impact factor paling tinggi di antara jurnal fisika.

Semangat seperti Murayama maupun Ma sangat positif tetapi sejarah membuktikan idealisme semacam ini tidaklah perlu. Beberapa senior kita tidak mau publikasi bila tidak di jurnal papan atas dan akhirnya memang tidak mempunyai publikasi atau karya satu pun sampai masa pensiunnya. Semangat umum ilmuwan Jepang patut ditiru, publikasikan hasil riset di jurnal internasional apapun. Makna jurnal internasional disini adalah untuk menjamin visibilitas karya tulis sehingga bisa diketahui oleh komunitas global. Selanjutnya kita tidak perlu menghakimi karya sendiri tetapi biarkan orang lain menilainya. Bagi kita yang terpenting adalah berkarya dan berkarya.

Kedua, kolaborasi akan menutupi kekurangan dan kelemahan individual para ilmuwan. Di Indonesia, ilmuwan khususnya fisikawan teori jumlahnya baru belasan. Mereka tidak boleh lagi bangga dengan institusi sendiri maupun almamater tetapi tanpa karya, tanpa publikasi. Sekarang banyak universitas kita yang mengakselerasi lahirnya guru-guru besar baru untuk meningkatkan status universitas. Sayangnya, dari setiap pengukuhan dapat dilihat bahwa guru-guru besar ini umumnya tidak mempunyai publikasi internasional kecuali saat menempuh program doktoralnya di luar negeri.

Kondisi paradoks tersebut dapat diatasi melalui kolaborasi. Salah satu contoh kolaborasi adalah Indonesia Center for Theoretical dan Mathematical Physics (ICTMP) yang melibatkan beberapa ahli fisika teori dalam dan luar ITB. Upaya ini memberi hasil dengan mulai munculnya hasil-hasil riset mereka di beberapa jurnal internasional. Jumlah ahli fisika teori Indonesia sekarang belum berubah secara signifikan dibanding tiga puluh tahun lalu. Tetapi kolaborasi telah membedakan dua generasi ini, publikasi menandai generasi yang belakangan. Juga komunitas ilmiah yang kuat sebagai motivator semangat berkarya seperti Grup Fisikawan Teoritik Indonesia (GFTI) yang menanungi pertemuan tahuan komunitas teori Indonesia, yaitu Workshop on Theoretical Physics.

Nobel bukanlah tujuan utama, yang lebih penting adalah tumbuhnya sikap dan tradisi ilmiah. Penyelesaian berbagai masalah akan jauh lebih efektif bila berdasar pemahaman sains dan tidak sekedar mengandalkan common sense. Di antara negara dengan jumlah penduduk terbesar seperti Cina, India, Amerika dan Indonesia hanya negeri kita yang belum menguasai ilmu pengetahuan. Padahal tanpa ilmu pengetahuan teoritis maupun praktis kita tidak akan mampu mengelola sumber daya alam yang melimpah yang pada gilirannya kita menjadi bangsa yang bergantung pada bangsa lain.

(Redirected from Japanese clothing)

This article is about traditional clothing in Japan. Although this traditional clothing described below is still seen at traditional festivals and ceremonies, western-style clothing is more commonly worn in daily life by both men and women. Japanese clothing is styled to fit the seasons; for instance in autumn people will wear clothes with fall colors and fall patterns. In the spring, bright colors and spring floral patterned Japanese clothing is worn.

Traditional clothing

Belt/Sash

Feet

During the winter, those wearing kimono tend to wear darker colors and may wear up to 10 layers of clothing. Especially at festivals and parades, people wear clothing like kimonos in Japan.

Japanese (日本語 ja-nihongo.ogg Nihongo ?) is a language spoken by over 130 million[2] people in Japan and in Japanese emigrant communities. It is related to the Ryukyuan languages. Its relationships with other languages remain undemonstrated. It is an agglutinative language and is distinguished by a complex system of honorifics reflecting the hierarchical nature of Japanese society, with verb forms and particular vocabulary to indicate the relative status of the speaker, the listener, and a person mentioned in conversation (regardless of his or her presence). The sound inventory of Japanese is relatively small, and it has a lexically distinct pitch-accent system. It is a mora-timed language.

The Japanese language is written with a combination of three different types of scripts: modified Chinese characters called kanji (漢字), and two syllabic scripts made up of modified Chinese characters, hiragana (平仮名) and katakana (片仮名). The Latin alphabet, rōmaji (ローマ字), is also often used in modern Japanese, especially for company names and logos, advertising, and when entering Japanese text into a computer. Western style Arabic numerals are generally used for numbers, but traditional Sino-Japanese numerals are also commonplace.

Japanese vocabulary has been heavily influenced by loanwords from other languages. A vast number of words were borrowed from Chinese, or created from Chinese models, over a period of at least 1,500 years. Since the late 19th century, Japanese has borrowed a considerable number of words from Indo-European languages, primarily English. Because of the special trade relationship between Japan and first Portugal in the 16th century, and then mainly the Netherlands in the 17th century, Portuguese, German and Dutch have also been influential.

Contents

Geographic distribution

Although Japanese is spoken almost exclusively in Japan, it has been and sometimes still is spoken elsewhere. When Japan occupied Korea, Taiwan, parts of the Chinese mainland, the Philippines, and various Pacific islands before and during World War II,[3] locals in those countries were forced to learn Japanese in empire-building programs. As a result, there are many people in these countries who can speak Japanese in addition to the local languages. Japanese emigrant communities (the largest of which are to be found in Brazil) sometimes employ Japanese as their primary language. Approximately 5% of Hawaii residents speak Japanese, with Japanese ancestry the largest single ancestry in the state (over 24% of the population). Japanese emigrants can also be found in Peru, Argentina, Australia (especially Sydney, Brisbane, Melbourne and Cairns), the United States (notably California, where 1.2% of the population has Japanese ancestry, and Hawaii), and the Philippines (particularly in Davao and Laguna). Their descendants, who are known as nikkei (日系, literally Japanese descendants), however, rarely speak Japanese fluently after the second generation.

Official status

Japanese is the de facto official language of Japan and in Palau, in the island of Angaur. There is a form of the language considered standard: hyōjungo (標準語?) Standard Japanese, or kyōtsūgo (共通語?) the common language. The meanings of the two terms are almost the same. Hyōjungo or kyōtsūgo is a conception that forms the counterpart of dialect. This normative language was born after the Meiji Restoration (明治維新 meiji ishin?, 1868) from the language spoken in the higher-class areas of Tokyo for communicating necessity. Hyōjungo is taught in schools and used on television and in official communications, and is the version of Japanese discussed in this article.

Formerly, standard Japanese in writing (文語 bungo?, "literary language") was different from colloquial language (口語 kōgo?). The two systems have different rules of grammar and some variance in vocabulary. Bungo was the main method of writing Japanese until about 1900; since then kōgo gradually extended its influence and the two methods were both used in writing until the 1940s. Bungo still has some relevance for historians, literary scholars, and lawyers (many Japanese laws that survived World War II are still written in bungo, although there are ongoing efforts to modernize their language). Kōgo is the predominant method of both speaking and writing Japanese today, although bungo grammar and vocabulary are occasionally used in modern Japanese for effect.

Dialects

Main article: Japanese dialects

Provincial differences of copula da

Dozens of dialects are spoken in Japan. The profusion is due to many factors, including the length of time the archipelago has been inhabited, its mountainous island terrain, and Japan's long history of both external and internal isolation. Dialects typically differ in terms of pitch accent, inflectional morphology, vocabulary, and particle usage. Some even differ in vowel and consonant inventories, although this is uncommon.

The main distinction in Japanese accents is between Tokyo-type (東京式 Tōkyō-shiki?) and Kyoto-Osaka-type (京阪式 Keihan-shiki?), though Kyūshū-type dialects form a third, smaller group. Within each type are several subdivisions. Kyoto-Osaka-type dialects are in the central region, with borders roughly formed by Toyama, Kyōto, Hyōgo, and Mie Prefectures; most Shikoku dialects are also that type. The final category of dialects are those that are descended from the Eastern dialect of Old Japanese; these dialects are spoken in Hachijō-jima island and few islands.

Dialects from peripheral regions, such as Tōhoku or Tsushima, may be unintelligible to speakers from other parts of the country. The several dialects of Kagoshima in southern Kyūshū are famous for being unintelligible not only to speakers of standard Japanese but to speakers of nearby dialects elsewhere in Kyūshū as well[citation needed]. This is probably due in part to the Kagoshima dialects' peculiarities of pronunciation, which include the existence of closed syllables (i.e., syllables that end in a consonant, such as /kob/ or /koʔ/ for Standard Japanese /kumo/ "spider"). A dialects group of Kansai is spoken and known by many Japanese, and Osaka dialect in particular is associated with comedy (See Kansai dialect). Dialects of Tōhoku and North Kantō are associated with typical farmers.

The Ryūkyūan languages, spoken in Okinawa and Amami Islands that are politically part of Kagoshima, are distinct enough to be considered a separate branch of the Japonic family. But many Japanese common people tend to consider the Ryūkyūan languages as dialects of Japanese. Not only is each language unintelligible to Japanese speakers, but most are unintelligible to those who speak other Ryūkyūan languages.

Recently, Standard Japanese has become prevalent nationwide (including the Ryūkyū islands) due to education, mass media, and increase of mobility networks within Japan, as well as economic integration.

Sounds

Main article: Japanese phonology
This article contains IPA phonetic symbols. Without proper rendering support, you may see question marks, boxes, or other symbols instead of Unicode characters.

All Japanese vowels are pure—that is, there are no diphthongs. The only unusual vowel is the high back vowel /ɯ/ U (Japanese).ogg listen , which is like /u/, but compressed instead of rounded. Japanese has five vowels, and vowel length is phonemic, so each one has both a short and a long version.

Some Japanese consonants have several allophones, which may give the impression of a larger inventory of sounds. However, some of these allophones have since become phonemic. For example, in the Japanese language up to and including the first half of the twentieth century, the phonemic sequence /ti/ was palatalized and realized phonetically as [tɕi], approximately chi Chi_(Japanese).ogg listen ; however, now /ti/ and /tɕi/ are distinct, as evidenced by words like [tiː] "Western style tea" and chii [tɕii] "social status".

The "r" of the Japanese language (technically a lateral apical postalveolar flap), is of particular interest, sounding to most English speakers to be something between an "l" and a retroflex "r" depending on its position in a word.

The syllabic structure and the phonotactics are very simple: the only consonant clusters allowed within a syllable consist of one of a subset of the consonants plus /j/. These type of clusters only occur in onsets. However, consonant clusters across syllables are allowed as long as the two consonants are a nasal followed by a homorganic consonant. Consonant length (gemination) is also phonemic.

Grammar

Main article: Japanese grammar

Sentence structure

Japanese word order is classified as Subject Object Verb. However, unlike many Indo-European languages, Japanese sentences only require that verbs come last for intelligibility.[4] This is because the Japanese sentence elements are marked with particles that identify their grammatical functions.

The basic sentence structure is topic-comment. For example, Kochira-wa Tanaka-san desu (こちらは田中さんです). Kochira ("this") is the topic of the sentence, indicated by the particle -wa. The verb is desu, a copula, commonly translated as "to be" or "it is" (though there are other verbs that can be translated as "to be"). As a phrase, Tanaka-san desu is the comment. This sentence loosely translates to "As for this person, (it) is Mr./Mrs./Miss Tanaka." Thus Japanese, like Chinese, Korean, and many other Asian languages, is often called a topic-prominent language, which means it has a strong tendency to indicate the topic separately from the subject, and the two do not always coincide. The sentence Zō-wa hana-ga nagai (desu) (象は鼻が長いです) literally means, "As for elephants, (their) noses are long". The topic is "elephant", and the subject is hana "nose".

Japanese could be considered a pro-drop language, meaning that the subject or object of a sentence need not be stated if it is obvious from context. (Note however that Chomsky's original formulation of this category explicitly excluded languages such as Japanese.) In addition, it is commonly felt, particularly in spoken Japanese, that the shorter a sentence is, the better. As a result of this grammatical permissiveness and tendency towards brevity, Japanese speakers tend naturally to omit words from sentences, rather than refer to them with pronouns. In the context of the above example, hana-ga nagai would mean "[their] noses are long," while nagai by itself would mean "[they] are long." A single verb can be a complete sentence: Yatta! "[I / we / they / etc] did [it]!". In addition, since adjectives can form the predicate in a Japanese sentence (below), a single adjective can be a complete sentence: Urayamashii! "[I'm] jealous [of it]!".

While the language has some words that are typically translated as pronouns, these are not used as frequently as pronouns in some Indo-European languages, and function differently. Instead, Japanese typically relies on special verb forms and auxiliary verbs to indicate the direction of benefit of an action: "down" to indicate the out-group gives a benefit to the in-group; and "up" to indicate the in-group gives a benefit to the out-group. Here, the in-group includes the speaker and the out-group doesn't, and their boundary depends on context. For example, oshiete moratta (literally, "explained" with a benefit from the out-group to the in-group) means "[he/she/they] explained it to [me/us]". Similarly, oshiete ageta (literally, "explained" with a benefit from the in-group to the out-group) means "[I/we] explained [it] to [him/her/them]". Such beneficiary auxiliary verbs thus serve a function comparable to that of pronouns and prepositions in Indo-European languages to indicate the actor and the recipient of an action.

Japanese "pronouns" also function differently from most modern Indo-European pronouns (and more like nouns) in that they can take modifiers as any other noun may. For instance, one cannot say in English:

*The amazed he ran down the street. (grammatically incorrect)

But one can grammatically say essentially the same thing in Japanese:

Odoroita kare-wa michi-o hashitte itta. (grammatically correct)

This is partly due to the fact that these words evolved from regular nouns, such as kimi "you" ( "lord"), anata "you" (あなた "that side, yonder"), and boku "I" ( "servant"). This is why some linguists do not classify Japanese "pronouns" as pronouns, but rather as referential nouns, much like Spanish usted or Portuguese o senhor. Japanese personal pronouns are generally used only in situations requiring special emphasis as to who is doing what to whom.

The choice of words used as pronouns is correlated with the sex of the speaker and the social situation in which they are spoken: men and women alike in a formal situation generally refer to themselves as watashi ( "private") or watakushi (also ), while men in rougher or intimate conversation are much more likely to use the word ore ( "oneself", "myself") or boku. Similarly, different words such as anata, kimi, and omae (お前, more formally 御前 "the one before me") may be used to refer to a listener depending on the listener's relative social position and the degree of familiarity between the speaker and the listener. When used in different social relationships, the same word may have positive (intimate or respectful) or negative (distant or disrespectful) connotations.

Japanese often use titles of the person referred to where pronouns would be used in English. For example, when speaking to one's teacher, it is appropriate to use sensei (先生, teacher), but inappropriate to use anata. This is because anata is used to refer to people of equal or lower status, and one's teacher has allegedly higher status.

For English speaking learners of Japanese, a frequent beginners mistake is to include watashi-wa or anata-wa at the beginning of sentences as one would with I or you in English.[citation needed] Though these sentences are not grammatically incorrect, even in formal settings it would be considered unnatural and would equate in English to repeatedly using a noun where a pronoun would suffice.

Inflection and conjugation

Japanese nouns have no grammatical number, gender or article aspect. The noun hon () may refer to a single book or several books; hito () can mean "person" or "people"; and ki () can be "tree" or "trees". Where number is important, it can be indicated by providing a quantity (often with a counter word) or (rarely) by adding a suffix. Words for people are usually understood as singular. Thus Tanaka-san usually means Mr./Mrs./Miss. Tanaka. Words that refer to people and animals can be made to indicate a group of individuals through the addition of a collective suffix (a noun suffix that indicates a group), such as -tachi, but this is not a true plural: the meaning is closer to the English phrase "and company". A group described as Tanaka-san-tachi may include people not named Tanaka. Some Japanese nouns are effectively plural, such as hitobito "people" and wareware "we/us", while the word tomodachi "friend" is considered singular, although plural in form.

Verbs are conjugated to show tenses, of which there are two: past and present, or non-past, which is used for the present and the future. For verbs that represent an ongoing process, the -te iru form indicates a continuous (or progressive) tense. For others that represent a change of state, the -te iru form indicates a perfect tense. For example, kite iru means "He has come (and is still here)", but tabete iru means "He is eating".

Questions (both with an interrogative pronoun and yes/no questions) have the same structure as affirmative sentences, but with intonation rising at the end. In the formal register, the question particle -ka is added. For example, Ii desu (いいです。) "It is OK" becomes Ii desu-ka (いいですか?) "Is it OK?". In a more informal tone sometimes the particle -no () is added instead to show a personal interest of the speaker: Dōshite konai-no? "Why aren't (you) coming?". Some simple queries are formed simply by mentioning the topic with an interrogative intonation to call for the hearer's attention: Kore-wa? "(What about) this?"; Namae-wa? (名前は?) "(What's your) name?".

Negatives are formed by inflecting the verb. For example, Pan-o taberu (パンを食べる。) "I will eat bread" or "I eat bread" becomes Pan-o tabenai (パンを食べない。) "I will not eat bread" or "I do not eat bread".

The so-called -te verb form is used for a variety of purposes: either progressive or perfect aspect (see above); combining verbs in a temporal sequence (Asagohan-o tabete sugu dekakeru "I'll eat breakfast and leave at once"), simple commands, conditional statements and permissions (Dekakete-mo ii? "May I go out?"), etc.

The word da (plain), desu (polite) is the copula verb. It corresponds approximately to the English be, but often takes on other roles, including a marker for tense, when the verb is conjugated into its past form datta (plain), deshita (polite). This comes into use because only keiyōshi adjectives and verbs can carry tense in Japanese. Two additional common verbs are used to indicate existence ("there is") or, in some contexts, property: aru (negative nai) and iru (negative inai), for inanimate and animate things, respectively. For example, Neko ga iru "There's a cat", Ii kangae-ga nai "[I] haven't got a good idea". Note that the negative forms of the verbs iru and aru are actually i-adjectives and inflect as such, e.g. Neko ga inakatta "There was no cat".

The verb "to do" (suru, polite form shimasu) is often used to make verbs from nouns (ryōri suru "to cook", benkyō suru "to study", etc.) and has been productive in creating modern slang words. Japanese also has a huge number of compound verbs to express concepts that are described in English using a verb and a preposition (e.g. tobidasu "to fly out, to flee," from tobu "to fly, to jump" + dasu "to put out, to emit").

There are three types of adjective (see also Japanese adjectives):

  1. 形容詞 keiyōshi, or i adjectives, which have a conjugating ending i () (such as あつい atsui "to be hot") which can become past (あつかった atsukatta "it was hot"), or negative (あつくない atsuku nai "it is not hot"). Note that nai is also an i adjective, which can become past (あつくなかった atsuku nakatta "it was not hot").
    暑い日 atsui hi "a hot day".
  2. 形容動詞 keiyōdōshi, or na adjectives, which are followed by a form of the copula, usually na. For example hen (strange)
    変なひと hen na hito "a strange person".
  3. 連体詞 rentaishi, also called true adjectives, such as ano "that"
    あの山 ano yama "that mountain".

Both keiyōshi and keiyōdōshi may predicate sentences. For example,

ご飯が熱い。 Gohan-ga atsui. "The rice is hot."
彼は変だ。 Kare-wa hen da. "He's strange."

Both inflect, though they do not show the full range of conjugation found in true verbs. The rentaishi in Modern Japanese are few in number, and unlike the other words, are limited to directly modifying nouns. They never predicate sentences. Examples include ookina "big", kono "this", iwayuru "so-called" and taishita "amazing".

Both keiyōdōshi and keiyōshi form adverbs, by following with ni in the case of keiyōdōshi:

変になる hen ni naru "become strange",

and by changing i to ku in the case of keiyōshi:

熱くなる atsuku naru "become hot".

The grammatical function of nouns is indicated by postpositions, also called particles. These include for example:

やった。Kare ga yatta. "He did it."
田中さんあげて下さい。 Tanaka-san ni agete kudasai "Please give it to Mr. Tanaka."

It is also used for the lative case, indicating a motion to a location.

日本 行きたい。 Nihon ni ikitai "I want to go to Japan."
カメラ。 watashi no kamera "my camera"
スキーに行くが好きです。 Sukī-ni iku no ga suki desu "(I) like going skiing."
食べますか。 Nani o tabemasu ka? "What will (you) eat?"
  • wa for the topic. It can co-exist with case markers above except no, and it overrides ga and o.
タイ料理がいいです。 Watashi wa tai-ryōri ga ii desu. "As for me, Thai food is good." The nominative marker ga after watashi is hidden under wa. (Note that English generally makes no distinction between sentence topic and subject.)

Note: The difference between wa and ga goes beyond the English distinction between sentence topic and subject. While wa indicates the topic, which the rest of the sentence describes or acts upon, it carries the implication that the subject indicated by wa is not unique, or may be part of a larger group.

Ikeda-san wa yonjū-ni sai da. "As for Mr. Ikeda, he is forty-two years old." Others in the group may also be of that age.

Absence of wa often means the subject is the focus of the sentence.

Ikeda-san ga yonjū-ni sai da. "It is Mr. Ikeda who is forty-two years old." This is a reply to an implicit or explicit question who in this group is forty-two years old.

Politeness

Unlike most western languages, Japanese has an extensive grammatical system to express politeness and formality.

Most relationships are not equal in Japanese society. The differences in social position are determined by a variety of factors including job, age, experience, or even psychological state (e.g., a person asking a favour tends to do so politely). The person in the lower position is expected to use a polite form of speech, whereas the other might use a more plain form. Strangers will also speak to each other politely. Japanese children rarely use polite speech until they are teens, at which point they are expected to begin speaking in a more adult manner. See uchi-soto.

Whereas teineigo (丁寧語) (polite language) is commonly an inflectional system, sonkeigo (尊敬語) (respectful language) and kenjōgo (謙譲語) (humble language) often employ many special honorific and humble alternate verbs: iku "go" becomes ikimasu in polite form, but is replaced by irassharu in honorific speech and ukagau or mairu in humble speech.

The difference between honorific and humble speech is particularly pronounced in the Japanese language. Humble language is used to talk about oneself or one's own group (company, family) whilst honorific language is mostly used when describing the interlocutor and his/her group. For example, the -san suffix ("Mr" "Mrs." or "Miss") is an example of honorific language. It is not used to talk about oneself or when talking about someone from one's company to an external person, since the company is the speaker's "group". When speaking directly to one's superior in one's company or when speaking with other employees within one's company about a superior, a Japanese person will use vocabulary and inflections of the honorific register to refer to the in-group superior and his or her speech and actions. When speaking to a person from another company (i.e., a member of an out-group), however, a Japanese person will use the plain or the humble register to refer to the speech and actions of his or her own in-group superiors. In short, the register used in Japanese to refer to the person, speech, or actions of any particular individual varies depending on the relationship (either in-group or out-group) between the speaker and listener, as well as depending on the relative status of the speaker, listener, and third-person referents. For this reason, the Japanese system for explicit indication of social register is known as a system of "relative honorifics." This stands in stark contrast to the Korean system of "absolute honorifics," in which the same register is used to refer to a particular individual (e.g. one's father, one's company president, etc.) in any context regardless of the relationship between the speaker and interlocutor. Thus, polite Korean speech can sound very presumptuous when translated verbatim into Japanese, as in Korean it is acceptable and normal to say things like "Our Mr. Company-President..." when communicating with a member of an out-group, which would be very inappropriate in a Japanese social context.

Most nouns in the Japanese language may be made polite by the addition of o- or go- as a prefix. o- is generally used for words of native Japanese origin, whereas go- is affixed to words of Chinese derivation. In some cases, the prefix has become a fixed part of the word, and is included even in regular speech, such as gohan 'cooked rice; meal.' Such a construction often indicates deference to either the item's owner or to the object itself. For example, the word tomodachi 'friend,' would become o-tomodachi when referring to the friend of someone of higher status (though mothers often use this form to refer to their children's friends). On the other hand, a polite speaker may sometimes refer to mizu 'water' as o-mizu in order to show politeness.

Most Japanese people employ politeness to indicate a lack of familiarity. That is, they use polite forms for new acquaintances, but if a relationship becomes more intimate, they no longer use them. This occurs regardless of age, social class, or gender.

Vocabulary

The original language of Japan, or at least the original language of a certain population that was ancestral to a significant portion of the historical and present Japanese nation, was the so-called yamato kotoba (大和言葉 or infrequently 大和詞, i.e. "Yamato words"), which in scholarly contexts is sometimes referred to as wa-go (和語 or rarely 倭語, i.e. the "Wa words"). In addition to words from this original language, present-day Japanese includes a great number of words that were either borrowed from Chinese or constructed from Chinese roots following Chinese patterns. These words, known as kango (漢語), entered the language from the fifth century onwards via contact with Chinese culture. According to a Japanese dictionary Shinsen-kokugojiten (新選国語辞典), Chinese-based words comprise 49.1% of the total vocabulary, Wago is 33.8% and other foreign words are 8.8%.[5]

Like Latin-derived words in English, kango words typically are perceived as somewhat formal or academic compared to equivalent Yamato words. Indeed, it is generally fair to say that an English word derived from Latin/French roots typically corresponds to a Sino-Japanese word in Japanese, whereas a simpler Anglo-Saxon word would best be translated by a Yamato equivalent.

A much smaller number of words has been borrowed from Korean and Ainu. Japan has also borrowed a number of words from other languages, particularly ones of European extraction, which are called gairaigo. This began with borrowings from Portuguese in the 16th century, followed by borrowing from Dutch during Japan's long isolation of the Edo period. With the Meiji Restoration and the reopening of Japan in the 19th century, borrowing occurred from German, French and English. Currently, words of English origin are the most commonly borrowed.

In the Meiji era, the Japanese also coined many neologisms using Chinese roots and morphology to translate Western concepts. The Chinese and Koreans imported many of these pseudo-Chinese words into Chinese, Korean, and Vietnamese via their kanji in the late 19th and early 20th centuries. For example, 政治 seiji ("politics"), and 化学 kagaku ("chemistry") are words derived from Chinese roots that were first created and used by the Japanese, and only later borrowed into Chinese and other East Asian languages. As a result, Japanese, Chinese, Korean, and Vietnamese share a large common corpus of vocabulary in the same way a large number of Greek- and Latin-derived words are shared among modern European languages, although many academic words formed from such roots were certainly coined by native speakers of other languages, such as English.

In the past few decades, wasei-eigo (made-in-Japan English) has become a prominent phenomenon. Words such as wanpatān ワンパターン (< one + pattern, "to be in a rut", "to have a one-track mind") and sukinshippu スキンシップ (< skin + -ship, "physical contact"), although coined by compounding English roots, are nonsensical in most non-Japanese contexts; exceptions exist in nearby languages such as Korean however, which often use words such as skinship and rimokon (remote control) in the same way as in Japanese.

Additionally, many native Japanese words have become commonplace in English, due to the popularity of many Japanese cultural exports. Words such as futon, haiku, judo, kamikaze, karaoke, karate, ninja, origami, rickshaw (from 人力車 jinrikisha), samurai, sayonara, sudoku, sumo, sushi, tsunami, tycoon and many others have become part of the English language. See list of English words of Japanese origin for more.

Writing system

Literacy was introduced to Japan in the form of the Chinese writing system, by way of Baekje before the 5th century.[citation needed] Using this language, the Japanese emperor Yūryaku sent a letter to a Chinese emperor Liu Song in 478 CE.[6] After the ruin of Baekje, Japan invited scholars from China to learn more of the Chinese writing system. Japanese Emperors gave an official rank to Chinese scholars (続守言/薩弘格/[7][8]袁晋卿[9]) and spread the use of Chinese characters from the 7th century to the 8th century.

The table of Kana. (Hiragana top, Katakana in the center and Romaji on the bottom.)

At first, the Japanese wrote in Classical Chinese, with Japanese names represented by characters used for their meanings and not their sounds. Later, during the seventh century CE, the Chinese-sounding phoneme principle was used to write pure Japanese poetry and prose (comparable to Akkadian's retention of Sumerian cuneiform), but some Japanese words were still written with characters for their meaning and not the original Chinese sound. This is when the history of Japanese as a written language begins in its own right. By this time, the Japanese language was already distinct from the Ryukyuan languages.[10]

The Korean settlers and their descendants used Kudara-on or Baekje pronunciation (百済音), which was also called Tsushima-pronunciation (対馬音) or Go-on (呉音).

An example of this mixed style is the Kojiki, which was written in 712 AD. They then started to use Chinese characters to write Japanese in a style known as man'yōgana, a syllabic script which used Chinese characters for their sounds in order to transcribe the words of Japanese speech syllable by syllable.

Over time, a writing system evolved. Chinese characters (kanji) were used to write either words borrowed from Chinese, or Japanese words with the same or similar meanings. Chinese characters were also used to write grammatical elements, were simplified, and eventually became two syllabic scripts: hiragana and katakana.

Modern Japanese is written in a mixture of three main systems: kanji, characters of Chinese origin used to represent both Chinese loanwords into Japanese and a number of native Japanese morphemes; and two syllabaries: hiragana and katakana. The Latin alphabet is also sometimes used. Arabic numerals are much more common than the kanji when used in counting, but kanji numerals are still used in compounds, such as 統一 tōitsu ("unification").

Hiragana are used for words without kanji representation, for words no longer written in kanji, and also following kanji to show conjugational endings. Because of the way verbs (and adjectives) in Japanese are conjugated, kanji alone cannot fully convey Japanese tense and mood, as kanji cannot be subject to variation when written without losing its meaning. For this reason, hiragana are suffixed to the ends of kanji to show verb and adjective conjugations. Hiragana used in this way are called okurigana. Hiragana are also written in a superscript called furigana above or beside a kanji to show the proper reading. This is done to facilitate learning, as well as to clarify particularly old or obscure (or sometimes invented) readings.

Katakana, like hiragana, are a syllabary; katakana are primarily used to write foreign words, plant and animal names, and for emphasis. For example "Australia" has been adapted as Ōsutoraria (オーストラリア), and "supermarket" has been adapted and shortened into sūpā (スーパー). The Latin alphabet (in Japanese referred to as Rōmaji (ローマ字), literally "Roman letters") is used for some loan words like "CD" and "DVD", and also for some Japanese creations like "Sony".

Historically, attempts to limit the number of kanji in use commenced in the mid-19th century, but did not become a matter of government intervention until after Japan's defeat in the Second World War. During the period of post-war occupation (and influenced by the views of some U.S. officials), various schemes including the complete abolition of kanji and exclusive use of rōmaji were considered. The jōyō kanji ("common use kanji", originally called tōyō kanji [kanji for general use]) scheme arose as a compromise solution.

Japanese students begin to learn kanji from their first year at elementary school. A guideline created by the Japanese Ministry of Education, the list of kyōiku kanji ("education kanji", a subset of jōyō kanji), specifies the 1,006 simple characters a child is to learn by the end of sixth grade. Children continue to study another 939 characters in junior high school, covering in total 1,945 jōyō kanji. The official list of jōyō kanji was revised several times, but the total number of officially sanctioned characters remained largely unchanged.

As for kanji for personal names, the circumstances are somewhat complicated. Jōyō kanji and jinmeiyō kanji (an appendix of additional characters for names) are approved for registering personal names. Names containing unapproved characters are denied registration. However, as with the list of jōyō kanji, criteria for inclusion were often arbitrary and led to many common and popular characters being disapproved for use. Under popular pressure and following a court decision holding the exclusion of common characters unlawful, the list of jinmeiyō kanji was substantially extended from 92 in 1951 (the year it was first decreed) to 983 in 2004. Furthermore, families whose names are not on these lists were permitted to continue using the older forms.

Many writers rely on newspaper circulation to publish their work with officially sanctioned characters. This distribution method is more efficient than traditional pen and paper publications.

Study by non-native speakers

Many major universities throughout the world provide Japanese language courses, and a number of secondary and even primary schools worldwide offer courses in the language. International interest in the Japanese language dates from the 1800s but has become more prevalent following Japan's economic bubble of the 1980s and the global popularity of Japanese pop culture (such as anime and video games) since the 1990s. About 2.3 million people studied the language worldwide in 2003: 900,000 South Koreans, 389,000 Chinese, 381,000 Australians, and 140,000 Americans study Japanese in lower and higher educational institutions.

In Japan, more than 90,000 foreign students study at Japanese universities and Japanese language schools, including 77,000 Chinese and 15,000 South Koreans in 2003. In addition, local governments and some NPO groups provide free Japanese language classes for foreign residents, including Japanese Brazilians and foreigners married to Japanese nationals. In the United Kingdom, studies are supported by the British Association for Japanese Studies. In Ireland, Japanese is offered as a language in the Leaving Certificate in some schools.

The Japanese government provides standardised tests to measure spoken and written comprehension of Japanese for second language learners; the most prominent is the Japanese Language Proficiency Test (JLPT), which features 4 levels of exams, ranging from elementary (4) to advanced (1). The Japanese External Trade Organization JETRO organizes the Business Japanese Proficiency Test which tests the learner's ability to understand Japanese in a business setting.

When learning Japanese in a college setting, students are usually first taught how to pronounce romaji. From that point, they are taught the two main syllabaries, with kanji usually being introduced in the second semester. Focus is usually first on polite (distal) speech, as students that might interact with native speakers would be expected to use. Casual speech and formal speech usually follow polite speech, as well as the usage of honorific.

    If you want to learn Japanese, you've come to the right place! On this site you will find such things as the Japanese alphabet (including Hiragana and Katakana) as well as Kanji, Japanese grammar, sentence structure, and useful Japanese phrases.

    The Japanese language is actually very simple but so unlike English that many English speakers find it difficult to learn Japanese. The goal of this site is to teach you the basics of the Japanese language and how to learn Japanese in a way that is, hopefully, easy to understand.
