What I Review &
How I Work

01
🔍
Japanese Website Localization Audit
A thorough QA review of your entire Japanese website — from homepage to pricing, help center, and checkout flow.
Who This Is For
Foreign SaaS, FinTech, AI, and payment companies that have a Japanese website but are unsure whether the Japanese content is natural, consistent, and trustworthy for Japanese enterprise users.
What I Review
  • Homepage, pricing page, and key landing pages
  • UI copy, button text, navigation labels, and form fields
  • CTA copy for natural Japanese phrasing
  • Terminology consistency across all pages
  • English strings left untranslated
  • Trust signals: company profile, legal pages, contact info
  • Error messages, validation text, and notification copy
  • Overall readability and natural flow

What I Review & Improve
  • Website pages, blog posts, and landing pages
  • Product documentation and API reference content
  • Release notes, changelogs, and announcements
  • Marketing and campaign copy
