Japan is the world's third-largest economy and one of the most demanding translation markets in the world. Japanese is not merely a different language — it operates through a fundamentally different communication logic, written in three interlocking scripts (hiragana, katakana, and kanji), and governed by an elaborate system of formality registers collectively known as keigo. For business, legal, and technical translation, correctly calibrating the formal register — whether sonkeigo (respectful language) or kenjōgo (humble language) — is not optional. It is the difference between a document that reads as professional and one that signals cultural unfamiliarity. Auerbach International has delivered professional Japanese translation services since 1991.

Our Japanese translation services are particularly strong in the domains where Japan excels globally: technical manuals and patents for automotive, robotics, and precision manufacturing companies; pharmaceutical and medical device documentation for PMDA (Pharmaceuticals and Medical Devices Agency) submissions; software and video game localization; legal contracts under Japanese law; and marketing content adapted for Japan's distinctive consumer culture. Japanese technical writing is famously detailed and precise — our translators bring that same precision to every project.

We use AI along with — not instead of — language professionals. AI translation tools have improved significantly for Japanese, but the three-script writing system, context-dependent kanji selection, and formal register system still require the judgment of a native Japanese-speaking expert. Our human translators review every document to ensure correct kanji usage, appropriate formality, and culturally accurate rendering of concepts that don't map directly between Japanese and English.

Every Japanese translation project at Auerbach is supported by dedicated project management, rigorous terminology consistency across large document sets, and a quality assurance process refined over three and a half decades of Japanese translation experience.
