Very small bath house with only about 10 lockers on each side. Single natural spring filled bath with two washing areas. There is a door leading to an outdoor sitting area but sadly no outdoor bath. Hopefully in the future. Built in 2018 this is brand new and has that new, fresh feeling to it. The connected soba restaurant looks delicious, but we arrived to late in the evening to also have dinner. Spring water is decent and noticeable but nothing too amazing. If you can get the tub to refill while you are in it, the spring water coming from the spout feels great.
