Native Japanese Localization, AI/LLM Training & Marketing | English

Native Japanese AI training, localization, and marketing specialist. I help global companies and publishers reach Japanese audiences with content that feels truly local — not translated. Most notably, I've contributed to book marketing and localization efforts that sold 600,000+ copies, and I train LLMs for accuracy, tone, and cultural nuance in the Japanese market. I combine native-level bilingual fluency with data-driven strategy and precise language execution — helping clients enter new markets, scale sales, and build products Japanese users trust. ━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT I DO BEST 🤖 AI / LLM Training • Prompts, instructions & dataset descriptions • Text classification & sentiment labeling • Chat/messaging annotation • Content moderation • LLM Japanese correctness & tone tuning • Model behavior guides • User testing for Japanese users 🌏 Localization & UX • Website, app & product localization • UX/UI text & onboarding flows • Japanese cultural adaptation • Help center & documentation localization • API documentation 📈 Marketing & Strategy • Book & product marketing for the Japanese market • Audience research & go-to-market localization • Project management experience (Lingble) ━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHY CLIENTS CHOOSE ME ✔ Native fluency in BOTH Japanese and English ✔ Proven results — 600K+ copies sold, 44 jobs, 100% success ✔ Cultural nuance most translators and AI tools miss ✔ Reliable, fast communication and clean project delivery Whether you're training a model, launching a product, or entering the Japanese market, I'll make sure it lands exactly right.
