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!

3世代旅行でした。2部屋を近くの部屋にしてほしいとリクエストしたら、コネクティングルームにしてくださいました。お風呂も気持ちよく、ラウンジ、卓球、将棋ととても楽しい時間を過ごさせていただき、感謝しています。難点はスタンダードルームで3人仕様だったのですが、エキストラベッドではなく、お部屋のソファーにシーツをかけお布団が置いてあったこと。フルフラットならともかく、背もたれのあるソファーで大人が寝るにはとても無理があり、結局1つのベットに2人入る羽目になりました。スタンダードルームでなければ、エキストラベッドを入れてもらえたのでしょうか(T_T)?3人でお泊まりの際はホテルに確認するか、もう1部屋おさえることをオススメします。
