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

This is a classic Japanese hot springs property with excellent hot springs water. You will get the full “ryokan” experience: Japanese tatami mat rooms, futons to sleep on, yukata to wear in and out of the bath, and even traditional wooden sandals to wear outside of the hotel. I loved the classic little touches - sweets and hot tea plus wet towels to greet us, hand written greetings from the hotel “kamisan” (owner) on our car each morning. The negatives were: WiFi extremely slow and accessible only in the lobby, limited and very creative English signage, and per person vs. per room charges making it a little expensive for families.

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。

温泉施設がいくつもあり、良かった。 特に温度の違う湯船が良かった。 また大浴場の他に貸切露天風呂や、有料貸切風呂もあり、次回はそちらも楽しみたいと思いました。連泊したので、料理は初日の方が良かった様に感じました。品数は多いですがもう少し工夫が欲しい様な。後朝食は洋食も欲しかったですね。

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。
