InsideOutJapan

InsideOutJapan is a Tokyo-based tour operator running walking and food tours in Japan, with over 5,000 walking tours a year.

Context

InsideOutJapan is a brand of MTJ Co., Ltd, a Tokyo-licensed travel agency running over 5,000 walking tours a year across Tokyo, Kyoto, the Japanese Alps and the Hiroshima area. Its guides are called Travel Storytellers. The digital project spans five different products, all built and maintained over time.

What I built

  • Traveler app (iOS and Android): walking tour catalogue, booking and card payment, trip access via booking number, support chat and self-paced audio tours.
  • Travel Storytellers app (iOS): where guides receive and accept job offers, access tour itineraries, support customers and get paid directly into their bank account.
  • Tour operator web platform (Travel Agent Hub): the area where partner agencies browse and book tours.
  • Internal admin dashboard: managing tours, bookings and content.
  • Public website: showcase and purchase of tours and services on insideoutjapan.com.

Outcome

  • Traveler app: 4.7 stars on Google Play (26 reviews) and 4.8 on the App Store, with 1,000+ downloads.
  • Ecosystem live and continuously updated since 2023, with the latest app release in July 2026.
  • Figures verified on 2026-10-02.

The store and website links are live. This is the traveler app listing:
