JAPAN'S FINEST ONSEN & SAUNA
The Finest Onsen & Sauna in Japan
57 SELECTIONS
Most of what we surveyed never even made it onto this site. This book is a further cut from what did. Our editor bathed in every onsen and sauna in it, and wrote only what they confirmed on the ground.

Feb 20–23, 2026 / 3 nights, 4 days
This marks my first visit to the Kanto region in about two months, since last December. I had been planning this trip well in advance, carefully selecting the finest facilities from a wealth of onsen and sauna options before finally setting off. Naturally, I arrived on-site Friday night and decided to kick off the journey at Shinagawa Sauna in Oimachi. An extraordinary trip, one destined to be deeply etched in my personal sauna history, is about to begin.
Every stop on this itinerary was visited in person by the Editor-in-Chief.
