For over 20 years, Crimson Japan has helped businesses communicate across borders, supporting Japanese companies expanding overseas and global companies entering Japan. What began as a translation service has grown into a full suite of multilingual solutions: translation, localization, interpretation, transcription, editing, and AI-powered language technology.
Every project draws on a network of 3,000+ contracted translators, editors, and linguists. This means we can assign a specialist who genuinely understands your subject matter, not just your language pair.
Four international certifications cover our translation processes, quality management, and data security, so you can trust both the quality of the work and the safety of your information.
We use Crimson Japan often, and the quality of their work is consistently outstanding. The translation style and accuracy never disappoint. They turned the quality level we were aiming for into reality.
