Historical onsen ryoken

The onsen Ryoken is a famous one in Japan as the Japanese Emperors had stayed at the estate for a few times. We stayed at a room with private onsen which is excellent. The food was also great and we had a great time.

Beautiful property. If you’re looking for a traditional Japanese experience, this is the place. FYI, if you have tattoos, you will not be able to use the public Onsen, but book a room with a private Onsen and you’re all set.

外観、内装が素晴らしいと思い、予約しました。予め『外観なし』と記載されていたので、期待はしていませんでしたが、あまりにも荒れ果てた庭？だったので、一緒に旅行した母親は文句タラタラでした。旅館に泊まると、売店での買い物が楽しみの一つですが、17時閉店の為、行こうと思ったら『終わりました』と言われ、がっかりです。お食事処や、大浴場までの距離も長く、老齢の母には辛かったようです。部屋風呂にも温泉がひいてあり、ゆったりした浴室だったのが、救いでした。

なかなか良い体験でした

広くて快適な部屋、散歩にちょうど良い庭、スタッフの気配りが心地よく、5月に続き、2度目の訪問です。今回部屋風呂が前回に比べて広かったので良かったです。食事も前回同様、美味しく、量も多過ぎず我が家には丁度良いです。食事の質を上げて更なる高級路線を目指すか、今のまま、親しみやすい高級感を楽しめる路線にするのか、中途半端な感じはします。
