Overview (history, characteristics, attractions)
Tamagawa Onsen (Kazuno City, Akita Prefecture) is a hot spring that springs up in the mountains near Towada-Hachimantai National Park, and is known as one of Japan's most highly acidic springs. It has a history of being used as a therapeutic hot spring since the Edo and Meiji periods, and the highly acidic waters are said to be effective against skin diseases, chronic eczema, and joint pain, so many people visit for medical purposes. The waters can appear milky white to brown due to the presence of iron and sulfur, and are attractive for their distinctive sulfurous smell and rugged natural scenery.
Highlights

- Bathing time: Because the bath is very stimulating, avoid bathing for long periods of time and take frequent breaks in short bursts (please follow the facility's instructions).
- Handling of metals and clothing: The highly acidic water may damage metals, some clothing, and accessories. Please remove any jewelry or ornaments before bathing.
- Crowds: It can get crowded on weekends, consecutive holidays, and during the autumn foliage season. It is best to make reservations in advance for public facilities and accommodations.

- Manners: Please follow the rules of the hot spring (pouring water over yourself, handling towels, areas where photography is prohibited, etc.), bathe quietly, and be considerate of other bathers and other nearby users.
