About Us

EIYAKU was founded to provide a dedicated, specialist JA > EN Language Service Provider, operating in the Legal, Medical and Technical domains where expert linguistic and domain knowledge are essential.

Unlike generic agencies where the Project Manager oftentimes has no knowledge of the source language, never mind expert domain experience, EIYAKU provides a superior , tailored service based on our decades of translation experience.

Founded by Christopher Spencer, a 20+ year veteran of the translation industry – we are able to deliver unparalleled service, quality and cost-effectiveness due to our hands-on, can-do approach.

Trusted by many of Japan’s leading corporations, as well as government ministry’s such as JETRO, METI and MEXT – you can be sure your project is in safe hands.
