Japanese Translation Services — Japanese ⇄ German.

Japanese translation services deliver certified German ⇄ Japanese documents, produced by sworn, court-authorised translators for authorities and courts here. Each translator's Landgericht appointment — from a German Regional Court — is what lets registry offices and the courts accept the certification on personal and corporate documents alike. Three scripts, honorific keigo registers and era-year dates are all handled correctly, with terminology kept consistent. Pricing is transparent from €1.09 per standard line.

Short & clear

Certified Japanese translations by sworn, native-speaker translators.

Reviewed by specialists · FÜD editorial team · kept current

Japanese mixes three scripts — kanji (漢字), hiragana (ひらがな) and katakana (カタカナ) — writes no spaces between words, and grades every sentence by politeness (keigo). Whether it is a family-register extract for a German registry office, a diploma for recognition, a contract with a partner in Tokyo, or technical documentation for an English-language project: the work is done by native Japanese specialists with a proven field.

We work in both directions and both pairings. Japanese ⇄ German is what German authorities, courts and local partners need — including certified translations, converted era-dates and passport-matched name readings. Japanese ⇄ English covers international business and life: contracts, technical files, applications and documentation that circulate in English.

Who it's for

Living in Germany, thinking in more than one language.

Most people who search for this in English are already fluent Japanese speakers dealing with a German system — or internationals and companies who use English as the working language. Both are covered.

Japanese → German, for the authorities

Family-register extracts (戸籍, koseki), certificates, diplomas and police records for a registry office (Standesamt), the immigration office or recognition of qualifications. Issued with era-year dates and kanji names, they need a certified German translation with the date converted and the name reading matched to your passport.

Japanese ⇄ English, for international business

Contracts, technical documentation, patents, references and company documents that an employer, university or partner abroad expects in English rather than German. Same specialists, same care with scripts and terminology.

German → Japanese, for home & market

German certificates, contracts, powers of attorney, manuals and rulings for authorities, courts, partners or family in Japan — in correct Japanese with the right register.

Business across the three

Companies trading with Japan, or teams that run in English while the paperwork is German or Japanese. We assign a specialist for the direction and field you actually need.

Language & script

Three scripts, no spaces, era-years, and readings you cannot guess.

A Japanese sentence weaves kanji (meaning), hiragana (grammar) and katakana (foreign words) together, with no spaces to mark where words begin and end. Politeness is grammatical: keigo shifts verbs and vocabulary by register, so the same fact reads very differently in a contract, a court statement or a company letter — and the wrong level is a real error, not a nuance.

Two things trip up official documents. Era-year dates: Japan counts years by imperial era (令和 Reiwa, 平成 Heisei), which must be converted to Gregorian on a certificate. And names: the same kanji can have several readings, so a name has to be matched to the passport rather than guessed, with the surname-first order handled correctly. For official use an authorised translator issues a certified translation; whether an apostille is also needed we check in advance — it is issued by the competent authority, not by the translation agency.

Quality you only notice at the receiving end

What only a native Japanese specialist catches.

Japanese looks at first like “a font problem, then translate” — and that is the trap: the three scripts, keigo, era-dates and kanji readings are its own. These pitfalls separate a native professional translation from one passed through, and they only surface at the receiving end.

Typical pitfalls in Japanese translation and how a specialist resolves them
PitfallWhy it goes wrongHow the FÜD solves it
Wrong politeness level (keigo)Keigo grades verbs and vocabulary by register. The wrong level makes a contract sound casual or a letter presumptuous — a substantive error in business and law.The register is chosen deliberately for the document type and relationship, so tone and standing are correct.
Three scripts mixed wronglyKanji, hiragana and katakana each have a job; misassigned, foreign names and grammar read wrong or ambiguous.Each script is used in its correct role, so the text reads as a native document, not a transliteration.
Era-date miscalculated令和/平成 years must be converted to Gregorian. A miscalculated year puts a birth or a deadline in the wrong place.Era-years are converted precisely and cross-checked, so dates on certificates are correct.
Name order & reading (furigana)One kanji name can be read several ways, and Japanese order is surname-first. Guessed, the romanised name diverges from the passport.Readings are matched to the passport and the name order handled correctly, so the ID and the translation agree.
Loanwords in katakana inconsistentForeign names and terms in katakana can be transcribed several ways. Varied across a file, one entity appears under two names.Katakana transcriptions are fixed once and kept consistent throughout the document.
Counters (助数詞) missing or wrongJapanese counts objects with classifier words. The wrong counter is ungrammatical and can blur quantities in a spec or contract.The correct counters are used, so quantities read naturally and unambiguously.
Full-width vs. half-width charactersMixing 全角/半角 forms and ignoring line-break rules (kinsoku) produces tofu boxes and broken layout in the PDF.Character widths and line-break rules are handled in typesetting, so the delivered document renders cleanly.

Why “fix the font, then translate” won't do here

None of these is a simple spelling mistake — most survive any spell-check. They arise at the seam of three scripts, a grammatical politeness system, imperial-era dates and unpredictable kanji readings, and they only surface at the receiving end: the registry office, the court, the business partner. That is exactly where native professional translation earns its place.

The difference shows not in the text, but at the receiving end.

So: native speakers with a field, the right register, converted dates and passport-matched readings.

Certification & recognition

“Notarised”, “authorised”, “certified” — what counts where.

Reviewed by specialists · FÜD editorial team · kept current

For submission to German authorities and courts, a court-authorised translator (in German, ermächtigter Übersetzer, publicly authorised under German state law) produces a certified translation with stamp, signature and certification note — recognised nationwide. Japan has no sworn-translator register; there, translations are authenticated through a notary (公証役場) and, where needed, an affidavit. The systems are not identical.

We clarify before the project which country the document is for and set the form valid there — following FÜD's documented quality process; where the service is delivered under DIN EN ISO 17100, the required second-person revision is included. Japan is a party to the Hague Apostille Convention, so where an apostille is required it is issued by the competent authority (the Ministry of Foreign Affairs) — the FÜD does not issue apostilles — and we tell you in advance whether it is needed.

Use cases

Japanese to German translation: three typical cases from practice.

Scripts, era-dates, target country and readings decide terminology and form of certification. Three common jobs — from the starting point to the result.

Registry office & family

Family register (koseki) Japanese → German

Starting point
For a marriage or naturalisation, a Japanese family-register extract (戸籍) is needed in German — with era-year dates and the name in kanji.
Process
An authorised translator renders the record, converts the era-dates to Gregorian and matches the name reading to the passport; the certification note makes it ready for the authority.
Result
A certified translation the registry office accepts — dates converted, name reading matching the ID, no follow-up query.

Business in English

Contract & technical file Japanese → English

Starting point
A company working between Japan and Germany needs a contract and technical documentation in English, with terminology kept consistent across the set.
Process
The register is set for the document type, katakana terms fixed once, and terminology handled by a specialist in the field with a native-speaker review.
Result
Documents an English-speaking partner can rely on — consistent terms, correct tone, no ambiguity.

Law & trade

Power of attorney German → Japanese

Starting point
A German company grants a power of attorney to a partner in Tokyo; legal form, register and terminology must be precise in Japanese.
Process
Legal terms stay demonstrable, keigo is set to the right level, scripts are used in their correct roles; a legal specialist checks the terminology.
Result
A document that is legally readable in Japan without replacing German legal institutions with foreign ones.

FAQ

Japanese translation – frequently asked questions.

Do you translate both Japanese to German and Japanese to English?

Yes. Japanese ⇄ German is the usual pairing for German authorities, courts and business partners; Japanese ⇄ English covers international business – contracts, technical files and documentation exchanged in English. A native-speaker specialist is assigned to each direction.

How do you ensure the right politeness level (keigo)?

The register is chosen deliberately for the document type and the relationship — a contract, a court statement and a company letter each call for a different level. A native specialist sets it and a second native speaker reviews it.

Do you convert era-dates (Reiwa, Heisei) on documents?

Yes. Japanese official documents count years by imperial era. We convert 令和/平成 years to the Gregorian calendar and cross-check them, so births, deadlines and validity are correct.

How do you write Japanese names — order and reading?

We handle the surname-first order and match the reading of the kanji to your passport, since one kanji name can be read several ways. The romanised name in the translation agrees with your ID.

Can you provide a certified Japanese translation recognised in Germany?

Yes. For certificates, diplomas and official documents an authorised translator (ermächtigter Übersetzer, authorised by a German court under state law) issues a certified translation with a certification note, recognised by German authorities and courts nationwide. Japan is a party to the Hague Apostille Convention; the apostille is issued by the competent authority, not the FÜD.

What does a Japanese translation cost?

The price depends on volume, field, direction and deadline. After a brief review we name a binding fixed price; standard certificates are usually a flat fee per document, from € 1.09 per standard line.
Our koseki extract was translated with the Reiwa dates correctly converted and my wife's name read exactly as in her passport. The registry office accepted the certified translation without a single question.

Work with us

Already a native Japanese speaker? Become an authorised translator.

Our Japanese translations are produced by native-speaker specialists — the reason German authorities, universities and courts accept them without queries. Beyond the language itself, that rests on German at C2 level, a specialist field the translator can defend, and — for certified work — court authorisation. If you bring that combination rather than bilingualism alone, we work with Japanese translators employed and freelance, and the way in is also open through an internship.

The path

German to C2, plus a field

Native Japanese is your starting capital; the market rewards what you build on top. German at C2 — the level at which you read a German ruling or medical report without hesitation — is the real gate, because certified work means rendering official German with precision, not just understanding it. Add a field you can defend (law, medicine, engineering, patents) and its terminology. That combination, not language alone, is what a registry office or a business partner actually relies on.

Why it holds up

Authorisation, and the expertise behind it

For certified translations you apply to the competent Regional Court (Landgericht) to be authorised under state law. And Japanese is exacting, specialist work: keigo register, era-date conversion and kanji readings that must match a passport. Careful human work here is what the receiving authority requires.
