Don't go

Room and beds were fine; great shower. The onsen bath was overrun with unsupervised children from a school trip. The food was absolutely terrible - the photographs made the food look enticing, but the quality was absolutely terrible. This was probably built as an up market resort, which then fell on bad times.

The hotel is very clean and well kept. However their dinner buffet option is expensive @ ¥6,000 but the quality is worth ¥800. The food is put plainly, lower than average. It’s much better spent taking a taxi and going into town. In addition one of the bath facilities was under construction making women and men hours timed. They still charged us “nyutouzei” which is bath tax. They should be lowering this or ridding it during the inconvenience. Otherwise the rooms are very clean.

Firtst room we got was far from the one that looked like on their advertising. So we got back to the front desk to complain and we received another room. The new room we got was slightly better and we kept it. However the room was decorated without any coziness and the accommodations were average and very poor for a japanese Hotel and the price we paid. Bathroom was nice though and it was clean. We paid almost 700€ in total for two nights which was a complete ripoff. Would never come back again!

According to the neighbor and the staffs, they opened April 2024 from previous old hotel with minor renovation. Very beautiful location and spacious property, but unfortunately the place needs improvement. 1 The carpet, specially, spa area smells as fungus. 2 So many steps are very dangerous for all people. For example, inside room bath have to step up around 10 inches, and public spa entrance also has big step when we enter. If the hotel in US, it will be not pass safety reason and ADA. No dining option besides around 9,000JPA buffet at night. The buffet was superb, including alcohol and fine deserts, but I don’t drink so the price is unreasonable for me and vegetarian. You need rent a car, other wise you can not go out from the area. A shuttle bus to go to the high way bus station is available. A souvenir shop available, but it is not convenient store, so if you need snacks and other things, highly recommend to get in town before go to the hotel. Good luck!

子連れが過ごしやすい宿です。 キッズスペースやラウンジ等、子供達が楽しんで過ごせました。 お部屋も開く清潔で過ごしやすかったです。 温泉は露天もあり広々して気持ちよかったですが、地下一階に内風呂と露天それぞれ1つで、温泉目的だと少し物足りなく感じるかもしれません。
