The Fours rooms (61 sq m) for up to 4 guests sit one at each end of the building on every floor, and each has an open-air onsen bath and an infinity-design terrace. There are also Fours rooms (55 sq m) for up to 4 guests and Triple rooms (55 sq m) for up to 3, both with an infinity-design terrace and an open-air onsen bath, so a family of up to 4 can stay in the same room.

The Twin (50 sq m) for 2 guests has comparatively few steps or changes in floor level, and there is one on each floor, though it is not a barrier-free room. Room equipment includes a humidifier, a hair dryer, an electric hot-water kettle, a refrigerator and a toilet with a washing function, and yukata, samue (a two-piece Japanese work outfit) and bathrobes are provided. The entire property is non-smoking, and all rooms, including their terraces, are non-smoking. On the adjacent site, a new inn, Bettei Ezo Fuji, is under construction from April 2026 to late December 2027 (planned).
