Owned by Omi Brotherhood Co., the Waterhouse house remained closed to the public until March 2023 when it was converted into a lodging facility. Up to seven people in the same family or group can lodge in this three-story Vories house.

The 1st floor has the kitchen, living and dining rooms and toilet. The 2nd floor has three bedrooms, meeting room, and bath/toilet. (The 3rd floor is closed.) Lots of windows make it bright and warm. Wi-fi, towels, toiletries, TV, and kitchen appliances provided.
At ¥132,000 per night to rent the entire house for up to 7 people, it's not cheap. Make reservations with the official website's contact form (in Japanese): https://waterhouse-kinenkan.com/
