House rules
Tamagawa Onsen (玉川温泉) is a therapeutic hot spring inn (toji ryokan) for recuperation. Many guest rooms do not have toilets, TVs, or refrigerators. Due to the highly acidic nature of the spring water, it may cause pain if it comes into contact with wounds or mucous membranes such as the eyes.
