Japanese Translation Services
Expert Japanese translation with mastery of keigo politeness levels, kanji precision, and cultural nuance. Specialized in technical, automotive, gaming, and business documents.
Japanese is the language of the world's third-largest economy and a critical gateway to one of Asia's most sophisticated consumer and business markets. Japan's influence spans automotive, electronics, gaming, anime, and precision manufacturing — industries where translation quality directly impacts business success.
Japanese is among the most challenging languages to translate accurately. Its three writing systems (kanji, hiragana, katakana) each serve different functions, and the complex system of politeness levels (keigo) requires translators who understand not just language but social hierarchy and business etiquette. Machine translation consistently fails with Japanese, producing text that ranges from awkward to incomprehensible, especially in formal business and legal contexts where keigo mastery is non-negotiable.
iTrex's Japanese translation team consists of native speakers based in Tokyo and Osaka, many with decades of specialization in automotive, technology, legal, and entertainment translation. Our translators understand the unspoken rules of Japanese communication — from the correct level of formality in a business email to the cultural adaptation needed for game localization — ensuring your content meets Japanese standards of quality and professionalism.

What Our Clients Say
Translating Japanese business correspondence requires an understanding of keigo honorific levels and formal register that most agencies get wrong. iTrex's Japanese linguists consistently produce translations that read naturally in the target language while preserving the appropriate level of formality from the source.
We localized our SaaS platform into 12 languages with iTrex, including UI strings, help documentation, and API error messages. They worked natively with our .json and .xliff files, which meant no reformatting on our end and a smooth integration with our CI/CD pipeline.
When we acquired a company in Brazil, iTrex translated the full due diligence package — shareholder agreements, financial audits, and regulatory filings — from Portuguese into English and French. Their legal translators caught nuances in Brazilian corporate law that a generalist agency would have missed.
