About
Hotel Sonia Otaru sits right by the canal, and its top-floor bath looks out over the water. The men's bath is indoor only, while the women's side adds an open-air tub. The spring water is the kind that keeps you warm well after you step out. Downstairs there's a casual sushi and grill restaurant. It's a straightforward city hotel, more about the view and the location than a resort experience.
