Summary

Bilingual Japanese-English business consultant with 20+ years of experience bridging global companies and Japanese stakeholders across business communications, localization, market entry, strategic partnerships, and executive engagement.

Throughout my career, I have personally created, reviewed, localized, and adapted high-stakes professional materials for Japanese and international stakeholders — including business documents, contracts and commercial materials, executive and client presentations, investor materials, market research, operating spreadsheets, and customer-facing communications.

Having served as a Co-Founder, Vice President, Japan Lead, and Asia Sales Director, I understand not only whether language is accurate, but whether a professional deliverable is commercially clear, culturally appropriate, internally consistent, and ready to be used with real clients, partners, investors, or executives.

My recent project work also includes AI and LLM evaluation, including rubric-based grading, response ranking, fact checking, rewriting, instruction-following and reasoning evaluation, hallucination detection, style and tone assessment, safety evaluation, localization-related review, and L2/final quality checks.

I currently advise international technology companies on Japan market entry, localization, GTM strategy, and strategic partnerships. Earlier in my career, I co-founded and built Rightsmith’s Japan business into a profitable multimillion-dollar operation and helped scale T3Media Japan from launch to approximately $3M in annual revenue.
