    About the Japanese Language

    Japanese (日本語) "Nihon-go" in Japanese) is the language spoken in Japan, in East Asia. Japanese uses three separate writing systems: hiragana, katakana, and kanji. The first two are phonetic systems (writing that shows the pronunciation of Japanese words), and kanji is the Japanese variation of Chinese characters (which show the meaning of Japanese words). The three systems are used interchangeably, and all three systems can often be found in the same sentence. The three systems are each reserved for different purposes.

    Little is known of the language's prehistory, or when it first appeared in Japan. Chinese documents from the 3rd century recorded a few Japanese words, but substantial texts did not appear until the 8th century. During the Heian period (794–1185), Chinese had considerable influence on the vocabulary and phonology of Old Japanese. Late Middle Japanese (1185–1600) included changes in features that brought it closer to the modern language, and the first appearance of European loanwords. The standard dialect moved from the Kansai region to the Edo (modern Tokyo) region in the Early Modern Japanese period (early 17th century–mid-19th century). Following the end in 1853 of Japan's self-imposed isolation, the flow of loanwords from European languages increased significantly. English loanwords, in particular, have become frequent, and Japanese words from English roots have proliferated.

    Japanese is an agglutinative, mora-timed language with simple phonotactics, a pure vowel system, phonemic vowel and consonant length, and a lexically significant pitch-accent. Word order is normally subject–object–verb with particles marking the grammatical function of words, and sentence structure is topic–comment. Sentence-final particles are used to add emotional or emphatic impact, or make questions. Nouns have no grammatical number or gender, and there are no articles. Verbs are conjugated, primarily for tense and voice, but not person. Japanese equivalents of adjectives are also conjugated. Japanese has a complex system of honorifics with verb forms and vocabulary to indicate the relative status of the speaker, the listener, and persons mentioned.

    Japanese has no genetic relationship with Chinese, but it makes extensive use of Chinese characters, or kanji (漢字), in its writing system, and a large portion of its vocabulary is borrowed from Chinese. Along with kanji, the Japanese writing system primarily uses two syllabic (or moraic) scripts, hiragana (ひらがな or 平仮名) and katakana (カタカナ or 片仮名). Latin script is used in a limited fashion, such as for imported acronyms, and the numeral system uses mostly Arabic numerals alongside traditional Chinese numerals.


    Japanese Document Translation

    Japanese official documents are written in standard Japanese (hyojungo) regardless of regional dialect. However, documents may vary in format depending on whether they are issued by municipal offices, prefectural governments, or national ministries. Historical family register documents (koseki) can use archaic kanji forms that require specialist knowledge.

    Japanese Document Types

    Key Japanese civil documents include koseki tohon (family register), jumin-hyo (residence certificate), and sotsugyou shomeisho (graduation certificate).

    Japanese is the de facto national language of Japan, though it has no explicit constitutional designation as the official language. All government documents, legislation, and judicial records are issued exclusively in Japanese. Japan's civil registration system (koseki) produces uniquely formatted family documents not found in other legal traditions.

    Industry Requirements

    The Legal Practice Board of Western Australia governs the legal profession in WA. The Law Society of Western Australia is the professional association, and the Legal Services and Complaints Committee handles disciplinary matters. At the federal level, the Attorney-General's Department oversees legal policy.

    Key documents requiring translation include court orders and judgments, statutory declarations and affidavits, powers of attorney, contracts and commercial agreements, wills and probate documents, police clearance certificates from overseas jurisdictions, and family law documentation including custody agreements and divorce decrees from foreign courts.

    All foreign-language documents tendered as evidence in Australian courts must be accompanied by a NAATI-certified translation. The Supreme Court of Western Australia and the Federal Court require certified translations for any non-English exhibits, and law firms routinely specify NAATI certification for client documents from overseas.

    Perth's legal sector handles substantial cross-border commercial work driven by the resources industry, with firms like Herbert Smith Freehills, Allens, and Clayton Utz maintaining large Perth offices. Family law and migration law practices across the city regularly require NAATI-certified translations of personal documents from South-East Asian, African, and Middle Eastern jurisdictions.
