Japan's top acidic hot spring, a therapeutic accommodation for health and wellness, with on-site nurses and meals tailored to your condition.
A therapeutic Property at the foot of Mount Yake. With a pH of 1.2 and a source temperature of 98 degrees, it offers Japan's most acidic Onsen directly without any additives. Designed for healing and relaxation, with a nurse always on-site. This Facility focuses on physical and mental health rather than tourism. Breakfast is a buffet, lunch is ordered with meal tickets, and dinner is cafeteria-style to promote health from within. For those wishing to enjoy the Onsen as a tourist attraction, please use the affiliated facility, Shin-Tamagawa Onsen.
It was an Onsen I wanted to visit at least once in my lifetime.It was wonderful.The water quality was astonishing—my first time experiencing anything like it.I can see why people say it can even help cure cancer.The food was delicious, too. The kiritanpo was simple yet full of flavor.The meal focused mainly on vegetables, but there was such a wide variety that I was very satisfied.
Yahoo!トラベルユー... 9/23/2026Breathtaking views with rising steam and a wonderful Onsen.I was very satisfied.You can also adjust the meal portions to your liking.I also enjoyed a day-use bath at Shin-Tamagawa Onsen using the guest-only ticket.If possible, a Shuttle Service bus from Tazawako Station would be a huge help for someone like me who doesn’t drive. I’d be happy to pay for a shuttle bus service.

Introduction of the Accommodation
Experience the comprehensive qualities of abundant water, spring quality, benefits, nature, and onsen culture.
A rare hot spring with hydrochloric acid as its main component, containing radium. The low-radiation hormesis effect, noted in the medical field, promotes natural healing abilities and revitalizes the body. This source boasts the highest discharge rate in Japan, ejecting approximately 9,000 liters per minute, known as "Obuki." The sight of hot water gushing, white smoke rising, and the accompanying sounds is truly spectacular.
The birthplace of Ganbanyoku, "Tamagawa Onsen," is a power spot where you can experience the energy of nature. Just a 5-minute walk away, there is a geothermal rocky area along the Tamagawa Onsen Nature Research Path. Ganbanyoku, or hot stone therapy, involves absorbing geothermal heat from the rocks into your body. It also contains trace amounts of radiation and abundant negative ions, which are known to promote metabolism and provide pain relief.
