岩手県花巻市の藤三旅館に行ってきました。湯治の宿としてもとても有名です。立ったまま入浴するお風呂もあります（撮影禁止）。
自炊場もあって自分で料理も出来ます。冬に行ったのですが、とても風情があって素敵でした。
I went to Fujisan Ryokan in Hanamaki City, Iwate Prefecture. It is also very famous as a hot spring inn. There is also a bath where you can bathe while standing (photography is prohibited).
There is a self-catering area and you can cook by yourself. I went there in winter and it was very atmospheric and lovely.
