Both the western-style and Japanese-style rooms have a bath where water flows directly from the hot spring, providing the luxury of fresh hot water at any time of the day. You will realize that you are embraced by nature when you have a view of the beautifully shining lake through the trees from the bedroom, living room, and from the bathroom.

The inn is located on the shore of a lake, which is covered with splashing waves on windy days. The name "RERA" (which means "wind" in Ainu) comes from the fact that nothing stands in the way of the inn and strong winds blow against it. The view from the bedroom windows and the indoor bath windows could not be more beautiful. RERA's own boat can be taken directly to the lake from just outside the inn, and fishing and other activities can be enjoyed at any time of the year when the lake is not frozen over.

FURE (meaning "red" in Ainu), named after the place Akayu, is a two-story inn with two bedrooms and a Japanese-style room space. With a sandy beach in front of the house, guests can go fishing on FURE's private boat anytime from spring to fall, and in winter, they can play in the snow on mountain skis or snowshoes. While soaking in the 24-hour hot spring, guests can enjoy the magnificent view of the lake from the front window and the marshy meadows from the north window.
