Tamagawa Onsen Ryokan

Ryokan in Tazawa-ko

This very local onsen resort is affordable and fun, especially for those well versed in Japanese custom (or those happy enough to bumble along!). The long rows of baths are known for their high acidity, which is supposed to detox internal organs. The dining area is cafeteria-style, and the rooms are remarkably spacious, many with Western beds.
