Indulge in one of Japan's finest Onsen at a mountain resort near Lake Tazawa.

Surrounded by beech forests, the Property features a warm, barrier-free design, ensuring a comfortable stay even for elderly guests.

I had long had this Accommodation on my list to visit, and chose it for a trip to celebrate my retirement.With no worries about the weather, I thoroughly enjoyed visiting the baths. There was also a free Shuttle Service from Shin-Tamagawa to Tamagawa,and the vigorously bubbling Onsen was truly impressive.Both the quality and quantity of the meals were excellent, and I was able to fully enjoy Akita’s local cuisine.
Yahoo!トラベルユー... 9/10/2026I finally visited this place I’d long wanted to see on a motorcycle trip. The food was delicious, the Room was clean and comfortable, and above all, the Onsen made me truly glad I came.

Introduction of the Accommodation
Experience the comprehensive qualities of abundant water, spring quality, benefits, nature, and onsen culture.
At New Tamagawa Onsen, we draw water from the same source as "Tamagawa Onsen." This water is a rare, strongly acidic spring with hydrochloric acid as its main component and contains radium. It promotes natural healing through the low-dose radiation hormesis effect, which has garnered attention in the medical field, helping to revitalize the body. The source boasts the highest single-point water output in Japan, gushing approximately 9,000 liters of spring water per minute from the grand spring (Ōbuki). The sight of it spewing hot water with white steam and sound is truly breathtaking.
The birthplace of Ganbanyoku, "Tamagawa Onsen," is a power spot where you can experience the energy of nature. It is about a 7-minute drive from Shin-Tamagawa Onsen. Along the Tamagawa Onsen Nature Research Path, there are geothermal rock formations. Ganbanyoku, or hot stone therapy, involves absorbing geothermal heat from these 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.
