Specializations
💳
FinTech & Payment Systems
Payment processing, banking APIs, remittance, compliance documentation, and financial UI. Knows the vocabulary that Japanese finance professionals expect — and what sounds wrong to a native ear.
⚙️
SaaS & API Documentation
Developer docs, API references, SDK guides, and product changelogs. Balances technical accuracy with natural Japanese phrasing — because "correct" machine output is still unreadable to real developers.
🤖
AI Translation Review
Reviewing AI-generated Japanese for unnatural patterns, overly literal phrasing, register mismatches, and cultural missteps. Trained to spot what DeepL and GPT consistently get wrong in business context.
📱
UI Copy & UX Writing
In-app messages, error text, onboarding flows, dashboard labels, and help center content. Small words carry big trust — and bad UI copy is why Japanese users abandon products.
🌏
Cross-Border Communication
20+ years living and working internationally — including 10+ years at a Bangkok-based Japanese tech company serving clients across Asia. Understands both the Japanese user mindset and the expectations of English-speaking product teams. Bridges the gap between "what the source says" and "what will land in Japan."

Why I Started Hiraki Localization

AI translation made it cheap for global companies to publish Japanese content — but cheap Japanese is not trusted Japanese. Japanese users are sensitive to unnatural phrasing, wrong register, and culturally tone-deaf copy. They leave. They don't complain, they just don't convert. Hiraki Localization exists to fix that gap: a quality partner who can review what AI produces and turn it into content Japanese users actually trust.

"I help global companies turn AI-translated Japanese into natural, accurate, business-ready content that Japanese users trust."
