First time of a ryokan

Very friendly staff and exquisit food on top of that. First time visiting a ryokan and was not disappointed! Three private onsens that i could use and very foreign friendly overall. Highly recommend to visit if you want a taste of ryokan life on your trip and worry of your tattoes forsbid you from using the onsen - it is totally ok att this place!

Staying at Shima Onsen was a real delight. I would highlight the incredibly friendly and gracious staff, who made me feel very welcome and looked after as a solo traveller, and made the beautiful dining experience even better. I enjoyed walking through the lovely nearby streets and forests - it felt very secluded and tranquil. And there was nothing better than coming back from a big walk to relax into one of the onsen - either public or private, depending on what you preferred. I wish I had more time to stay, but even two nights was enough to feel very rejuvenated.

I really enjoyed my stay at Kashiwaya Ryokan. Although it was long to get to without a car, it was worth the travel. The 2 days there didn’t feel like it was enough time. I will return again for sure. The room was comfortable, the private onsen were beautiful and amazing. The kaiseki served at dinner were delicious and perfectly balanced. The traditional Japanese breakfast (there were Western styled breakfast and brunch at the cafe in Shima Onsen town) was incredible as well. I want to thank the dedicated staff members I interacted with during my stay. They were kind and patient. I don’t recall all their names but I want to thank Hitomi, Yuho and Andrew for their help. I will recommend this ryokan to my friends.

Room was clean, only had one bug come into the room and was easy enough to put outside. Staff were friendly, I forget there names but the people who waited on me and at reception were friendly, polite and helpful. Nice and peaceful and onsen was great. Loved the food here, it was the best food I ate in my month long trip to Japan and would 100% come back here

年輕人現代化的管理，人員英文流利，但保持温泉旅館的傳統，非常好！有關山中小昆蟲的處理方法很可愛，餐膳口味比較傳統偏甜，周邊沒有便利店補及零食，入去中之条前要買好。

いつ訪れても変わらず素敵な宿です。

7年ぶりに宿泊しました。とても静かな中で川のせせらぎが聞こえてくるので本当に癒されます。お風呂も貸し切り温泉が3つあり、好きな時に入れるので大満足です。食事もとても美味しく、あゆの炊き込みご飯が絶品でした。朝食のパンと、リンゴジャムが本当に大好きです。一番大好きな温泉宿です。少し離れた場所にある柏屋カフェも大好きで、イタリアンラーメンがとても美味しくて毎回必ず行きます。今回久しぶりにいただきましたが、お店の雰囲気も変わらず素敵で、イタリアンラーメンも美味しかったです。最近は海外ばかりで気づけば7年も訪れていませんでしたが、またぜひ宿泊させていただきたいです。
