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.
This is our second stay at the accommodation following last month, as part of my mother's therapeutic visit. Everything is absolutely perfect. The staff, the people we pass by in the facility, and even other guests staying for similar purposes all exude kindness and warmth. The bath, in particular, has a unique and charming atmosphere. Unfortunately, due to work commitments this year, it will be difficult to visit before it closes for the season. However, once it reopens next year, I am determined to bring my mother back here again.
Yahoo!トラベルユー... 10/13/2025It was a warm November, and I wondered if it was too early, but just in case, I used winter tires. The weather in the mountains can change quickly, and the next day it snowed. It was safe, so on the way back, I enjoyed the last autumn leaves while descending. The bath was relaxing and allowed me to fully enjoy the season. I'm looking forward to visiting again next spring!

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.
