黄金温泉 カルデラ温泉館

Ogon Onsen Caldera Onsenkan is a small village-run day bath near Hijiori onsen (肘折温泉), a hot spring village in the mountains of Yamagata. The indoor bath is warm and faintly salty, with a touch of cloudiness to the water, while the outdoor bath alternates between men's and women's use through the day and tends to run cooler, easy to sit in for a while and watch the clouds roll through the valley. Wash up in the indoor bath first, since the outdoor one has no washing area of its own. One corner of the indoor bath is set up for drinking: a stone basin fed by cold, naturally carbonated spring water, rare enough to have its own following, and it also doubles as a spot to cool hands and feet between hot soaks. There's a resting room, but no restaurant on site; meals are next door at Hijiori Ideyu-kan (肘折いでゆ館).
