Akakura Onsen, Myoko, Niigata Prefecture
Akakura Onsen Taki-no-Yu Open-Air Bath
A good-value seasonal pick from spring through autumn if you want to try one of Myoko's best-known large outdoor baths. It is closed in winter and is not a fixed-facility spa; choose somewhere else if you need a guaranteed summer pool or extensive indoor amenities.
