Japanese Localization QA Specialist — 15+ years of Japanese–English translation experience across IT, FinTech, payments, SaaS, and AI tools.

Japanese Localization QA — Native Expertise, Actionable Reports

I'm Munehiro Hiraki, a Japanese Localization QA specialist helping foreign SaaS, FinTech, and AI companies make their Japanese content natural, accurate, and business-ready for the Japanese market.

My work covers language quality, technology, and cross-border business communication. I don't just correct translation errors — I help companies understand what it takes to earn trust from Japanese users, and I deliver every finding in a format any team can act on, even without reading Japanese.

Background & Experience

With 15+ years of Japanese–English translation experience, I have built deep specialization in IT, FinTech, payment systems, APIs, SaaS products, and developer tools. My background is rooted in real-world business translation — not academic or general-purpose work — which means I understand the terminology, the industry conventions, and the standards that Japanese business users actually expect.

I spent more than a decade working with a Bangkok-based Japanese IT and FinTech company, where I was deeply involved in cross-border product localization, payment system documentation, API content, and internal technical communication between Japanese and international teams. This experience gave me a rare combination: native Japanese language instinct, FinTech domain expertise, and a genuine understanding of what foreign companies need to succeed in Japan.

Global Project Experience

Why I Started This Service

AI translation has made it cheap and fast to produce Japanese content — but it has also created a new problem for foreign companies entering Japan: content that is technically understandable, but not natural, not consistent, and not trusted by Japanese users. I've seen this pattern first-hand across FinTech, SaaS, and AI products.

Hiraki Localization exists to fix that. Not by replacing AI translation — but by making it reliable. I work as a quality partner, not just a translator. Every engagement produces findings your entire team can read and act on, whether or not they read Japanese.

My Commitment

"I help global companies turn AI-translated Japanese into natural, accurate, business-ready content that Japanese users trust. Every engagement produces clear, visual output your entire team can read and act on — whether or not they read Japanese."
