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.

Even in the world of sauna, there exist places known as sacred grounds — destinations that sauna lovers across Japan dream of visiting at least once in their lifetime. This journey begins at Kobe Sauna & Spa, one of Kobe's most revered sites, and continues through Ogaki Sauna, Sauna Shikiji, Fujisan Natural Water SPA Sauna Takanoyu, Suruga Health Land, and Well-Be Sakae — six legendary facilities in total. It is an outrageously spectacular route. When the itinerary was finalized, my entire body trembled with excitement. And a once-in-a-lifetime experience was waiting for me.
Every stop on this itinerary was personally visited by our editors.
