751. Shiroganeyu, Ginzan Onsen, Yamagata An onsen for ¥500. The stated hours are 08:30 to 15:00 (except Wed). Admission is limited to 30 minutes. No change is given, strictly. One staff member was a very unpleasant man who refused to give change from ¥1000, and aggressively shoved the rules at me, acting rather rude overall. Shiroganeyu was designed by Kuma Kengo, but there is nothing particularly special about the design, and the condition of the facility itself is very poor. There is an indoor bath on the first floor. The water is a little cloudy, with a slight greenish tint. The temperature is 44.5. It is easy to breathe inside, even though it was very steamy. A strange facility, for me it is a mystery why its condition is so bad and the staff are so negative. 09.01.2026
