Udon Restaurant
The Rai Yumeto no Ie Onsen (meaning Dreamers House in English) is a small hot spring building located across from Nakatoya Hot Springs Campground. During the summer this onsen is a popular spot for the campers there. On the off season, its quieter and still a great place to freshen up, relax in the onsen waters, or to fill up on bowls of udon noodles at the restaurant there. The building itself has a rustic feel. The wood used to make this onsen comes from two hundred year old Finnish pine imported along the Siberian railroad and shipped across.

The onsen has seven washrooms and is segregated. They also have hairdryers, shampoo, body soap available. Towels are also available to purchase and there is a massage machine that can be used. Everything to clean up and relax. There is a small udon restaurant in the building. Here you can order a variety of hot udon noodle dishes which will satisfy hungry customers. The onsen also has information and pamphlets on what to do around the Toya area, so it acts as a tourist site as well!
Rustic settings
From its humble and early beginnings, Boyotei Restaurant has become a popular spot to enjoy a nice lunch or coffee in the surroundings of Lake Toya. Originally starting out as a small coffee shop in 1946, it has become a cozy, tavern like restaurant that serves up some delicious Western fare. There is plenty of seating in the rustic setting for couples and groups (for larger groups it is better to book ahead). It is located near a few of the sightseeing spots south of the lake, such as the Mt. Usu Memorial Park, and the G8 Summit Memorial.
