Localized 2FA app for Japan

Build a Japanese-language alternative to Google Authenticator with regional UX patterns. Serves privacy-conscious users who prefer local software.

Why now

Global 2FA apps often ignore local UX norms—Japan's top ranking shows strong demand for auth tools.

Who for
Japanese business users
Business model
Enterprise licensing
Effort
A few weeks

Japanese users need 2FA but may distrust foreign apps. A locally-built authenticator could offer:

  • SMS fallback for older users
  • Bank/business integrations
  • Minimalist UI matching Japanese design

Start with TOTP support and one bank integration. Partner with local security auditors for trust.

Risk: competing with Google's brand recognition.
