Tamagawa Onsen
Tamagawa Onsen is one of Japan's premier hot springs, located in the mountainous area of Senboku City, Akita Prefecture. This onsen boasts two "number one" features. The first is its overwhelming flow rate of 9,000 liters per minute, and the second is its highly acidic hot spring water with a pH level of 1.2. This level of acidity is more potent than household vinegar or lemon juice, earning its reputation for treating various ailments. The water emits a sulfurous odor and contains trace amounts of radium radiation, truly allowing visitors to feel the power of nature.
There is only one accommodation facility, designed as a genuine onsen retreat for healing and recuperation. Nurses are on-site, and there are both ryokan (inn) and self-catering options available. Additionally, near the accommodation, there is a natural rock bath where guests can spread out blankets or mats on the grassy area to relax. The adjacent "Tamagawa Onsen Nature Research Trail" is about a 1 km walking course where you can experience the remnants of volcanic activity, including the source "O-Datsu," "rock formations," and "fumaroles."
This area is within the Towada-Hachimantai National Park, allowing visitors to enjoy the beautiful nature of all four seasons, particularly the breathtaking views during the fresh green and autumn foliage periods. Tamagawa Onsen offers the ultimate healing experience for those seeking solace for both body and mind in harmony with nature.
