Obihiro Sauna Complete Guide｜An Ultimate Sauna Journey in Tokachi, the Sanctuary of Relaxation

Tokachi proudly brands itself as the “Sauna Kingdom” of Japan. At its heart, Obihiro offers the perfect routine to relax and rejuvenate: warm your core in moor hot springs, sweat it out with Finnish-style löyly, cool down in crystal-clear water from mountain streams, and finish with a refreshing outdoor breeze under Tokachi’s blue skies. From luxury resorts to hidden gems at public bath prices, this guide explores six outstanding sauna spots. Whether you’re a beginner or a seasoned enthusiast, this is your go-to navigation for a sauna journey in Obihiro.

Four Reasons Why Obihiro is Called the “Sauna Kingdom”

1. Pre-sauna Effects of Moor Hot Springs— Natural humic acid creates a moisture barrier and boosts perspiration.
2. Authentic Sauna Rooms Using Tokachi Materials— Featuring bakuhanseki stoves and birch vihta, just like in Finland.
3. Exquisite Cold Baths from the Satsunai River and Groundwater— Maintains 10–15°C year-round with soft, chlorine-free water.
4. Refreshing Outdoor Air under Tokachi Skies— Over 70% sunshine rate, crisp and dry even in midsummer.
