Onsen felt like it wasn't real onsen and all the baths were lukewarm and not hot. Room was non smoking but smelt like cigarettes real bad like somebody was just here a day ago chain smoking. Actually bought room deodorizer for cigarettes and left it there. Parking was infested with weeds that sticks to your clothes took me 20 min to remove. Meal was part of the reservation but that wasnt communicated clearly to me. They ended up calling me asking me if im coming down for dinner twice even when i told them i dont need meal since already had plans. Not a big deal but stay tax could only be paid in cash. Out of all the hotels i stayed at japan this place is the only place that said cash only. I wonder what they would have said if i told them i dont have cash. With that in mind i dont think they were being truthful and was just being lazy. The hotel seems like it has some history but the proper investment is not being made. Could be better if they have the right mindset.

夕食のお料理がかなり薄味でした 朝食のカレーは甘口でしたが美味しかったです。 お風呂は表示より少しぬるい気がしました。 長く浸かるのが目的なのかな？ 日帰りで入浴されている方がかなりいらっしゃるようです。大きくタトューが入っている方もいらっしゃいました。お子さんもはいるのて、そこは強く明示してくれると助かります。

掛け流しの温泉、私の身体にとても合う温泉だった。 また、従業員の手作りの、朝焼けの富士山と、ダイヤモンドご来光が独り占めできる、貸し切り露天風呂。 　好みの浴衣を着て、一日に何度も温泉へ入り、すべてのストレスを洗い流せる。 　 　建物は、昭和時代のまま。 昭和のひとには懐かしくて、帰る頃には令和の行き過ぎた便利さを残念に思うようになっていた。 　とても貴重なお宿だった。

設備は古く、ビジネスツインには鏡や洗面所・トイレがありませんでした。しかし、大浴場のすぐ前なのでそこを代わりに使うことができます。 値段がお安いのでこれでもいいかと思いました。 事前支払いの金額を見ると、税金が割と高めに設定されているように感じるのですが、どういう明細なのでしょうか。それとは別にチェックアウトの時に、入湯税を150円現金で支払う必要がありました。

ビジネスプランの割安価格で宿泊させてもらいました。 元々が寝るだけの予定で予約してたので、部屋に不満は無し、防音なのかロビーで卓球を楽しむ親子の声も気にならず、それよりも気に入ったのが150円の入湯料で大浴場やプライベート露天風呂が利用できた事。 そして大好きな昭和の風情が残るこのホテルに年内にまた宿泊する事だろう。

Outdoor onsen is unforgettable..

Stunning view of oceanfront atop cliff and, the view from outdoor onsen (gender separated) was absolutely breathtaking.. seeing the ocean splashing against rocks just few feet away as you bathe watching the sunset.. a must experience for any avid hot spring fans. Area doesn’t offer many eatery choices, but if you’re driving a rental, there will be more options in both directions on highway 136. Convenience store within walking distance, a lifesaver for last minute food shopping for families with younger children
