*CLOSED* Small. Very small. That said it has the highest quality well of all the Yamato no Yu chain supersento that I’ve been to. The water has a good silky feel to it that stays with you well after getting out of the bath. Sadly the locker room and bathing areas are small. So are the entrance and lounge areas—this is common for the Yamato no Yu chain however. When I went the heater for the main shallow indoor bath was broken it was being filled with the spring water at its natural temperature of about 37 degrees and I loved it. Mia had a ton of fun in the warm water. It is a great contrast to the heated spring water in the outdoor baths. So again, it is small. Too small. try to go on a normal weekday and not a holiday night like we did. If you live in the area, be happy you have pretty decent supersento near by.
