For Travelers

Bespoke Onsen Retreats

A bespoke journey that brings the Japanese practice of Toji into a contemporary stay. Through consultation, we clarify the purpose of your trip, preferences, timing, companions, and desired pace, then shape spring characteristics, stays, meals, and routes into one itinerary. AI and data help compare options; the final recommendation is refined through 15 years of field notes and human judgment.

  • Route and stay allocation

For Business & Investors

AI Market Research

We organize public information about Japan’s onsen industry together with the assumptions you provide, then analyze an agreed research question such as ryokan M&A opportunities, onsen-district revitalization, or inbound demand. AI supports information organization and comparison; a person verifies sources and assumptions in the final report.

Why NAPU

  • 15 Years of Field Notes
  • One-to-One Consultation

  • Human Final Judgment
