We went there for a day. The owners were super friendly and generous. The room is cozy and simple and the lounge area is very traditional.

旅館主人非常用心經營，非常舒服有回到家的感覺(*ﾟ∀ﾟ)早餐簡單好吃，語言溝通無礙，很棒的住宿經驗(^^♪

Japanese young owners and staff are very kind. They give absolutely outstanding services! Rooms were a bit small but very clean. Rooms were all private rooms. 2 private shower rooms in the first floor. No toilet in the guest room. We have been to Hakuba many times, and regret that we should have known here.

Koji-sans guest house was incredible. The owners went out of their way to make our stay amazing. They drove us to the ski mountains, translated for us, had a piano concert for all the guests, cooked us an amazing lunch, and genuinely enjoyed just talking with us. The rooms were very comfortable, the breakfast was great, and we could not have picked a better place to stay. We will definitely be back next year!
