Senior EN-JA IT and software localization specialist with over 15 years of professional experience in translation,
review, LQA (Language Quality Assurance), and localization quality management.
I have been working in the localization industry since 2005 and as a full-time freelance translator since 2011,
handling high-value projects including software and web UI, AI and machine learning content, SaaS platforms,
game development tools, online training courses, and technical documentation.
My background includes working at a major localization vendor in Tokyo as a translator, reviewer, project manager,
and in-house evaluator responsible for screening and qualifying translators through trial tests.
This enables me to assess linguistic quality not only as a linguist, but also from a vendor-side quality control and delivery perspective.
In addition to translation and review, I also perform LQA (Language Quality Assurance) in real production environments,
acting as a third-party quality gate after translation and review processes to ensure release-ready quality.
I specialize in delivering Japanese that is not only accurate, but also clear, consistent, user-focused, and suitable for real-world products and services.
