A hilltop front-row seat to spectacular night views and a tea-brown moor spring
Yamanashi Ichikawamisato Town
Located on a hill at an elevation of 370 m, this bathing facility offers sweeping panoramic views of the Kofu Basin and famous peaks such as the Yatsugatake Range. Its scenery is exceptional — it was the first hot spring facility to be selected for Japan's "Top 100 Night Views" — and the nightscape is particularly memorable. The water is a tea-brown moor spring containing ancient plant-derived organic matter, and its alkaline simple hot spring quality gives it a soft, smooth feel on the skin. You can enjoy the spectacular views from the sauna and the cold plunge bath as well, and cooling-off sessions outdoors while gazing at the vast landscape provide a blissful totonou experience.
