Hot spring facility is very good. We lived in main building & there are one public onsen & 3 private onsen available. Private onsens are very good, family can use one by locking inside & putting a board to show “occupied” on the entrance, then to enjoy your private time. 3 private onsens are different size & I think the large one can be available for 4 slim ladies. Private bathroom & washroom attached to our room without warm air, it is too cold to take a bath or to use washroom in winter with only few celsius degree outside. As we don’t like to eat uncooked food & fish, we hadn’t taken dinner there. If menu for more cooked food can be provided, it would be much appreciated. Overall, it is a nice place to state. Fee parking, attractive decoration and wonderful onsen. Staff are polite even we only bought room accommodation.
