Japanese Localization & Proofreading | Websites, Apps, AI Products
Top Rated | 49+ Upwork jobs | Native Japanese localization for websites, apps & AI products I help global companies make their Japanese read as if it was written in Japanese from the start, not "translated." ■ RECENT PROJECTS - Hotel booking website: reviewed the Japanese booking interface (EN → JA) for natural, consistent wording - iOS puzzle game: Japanese App Store description and in-game text - AI company: Japanese website localization and event materials - Company website: English-to-Japanese translation review - Documentary videos: proofread Japanese narration scripts, fitted them to the video timing, and produced the Japanese AI voiceover in ElevenLabs - AI training: evaluated 700+ pairs of AI voices, wrote 200+ Japanese scripts, and scored AI summaries and answers - Other work: card game manuals, online casino event copy, and SEO articles on FX trading ■ WHAT I DO 1) Website & app localization review: UI text, buttons, headlines, booking flows, App Store listings 2) Proofreading of human, machine, and AI translations 3) Marketing localization and transcreation 4) Japanese AI evaluation and AI voiceover scripts ■ HOW I CHECK QUALITY - I compare every line with the English source: meaning, numbers, names, and links - I keep terms and tone consistent across all pages (with a glossary if needed) - I check that headlines and buttons fit the layout and read naturally - I use standard Japanese wording for pricing, legal, and cookie notices - I leave a comment when something is unclear, instead of guessing - I do a final read-through before every delivery ■ FILES & TOOLS Google Docs / Sheets, Excel, Word, PDF comments, ElevenLabs. Happy to learn your CMS or localization platform. ■ LARGE-VOLUME & RUSH PROJECTS Feel free to ask about large-volume or urgent projects. I sometimes use AI tools (ChatGPT, Claude) with data-training turned off to work faster, and every line is checked and finalized by me. Human-only work is also available. ■ HOW TO START Send me a page list or a short sample. For bigger sites, I'm happy to start with a small paid test so you can check my work first. Hiromi
