Kobo no Yu Honten

This day-use hot spring bathhouse also used as a hot spring health spa is located about a four-minute drive from the Izu-Nagaoka Station on the Izuhakone Railway. Guests can enjoy bedrock baths made with ample amounts of Bad Gastein stone of Austria and hokutolite, a mineral from Tamagawa Onsen in Akita Prefecture designated as a Special Natural Monument, as well as mist saunas and other bathing facilities. The bathhouse's Radon no Yu baths are fed entirely by free-flowing hot spring water from Kona Onsen. The alkaline simple hot springs are said to aid recovery from fatigue and to help with conditions including nerve pain, lower back pain, and stiff shoulders. The bathhouse's nearly 5,000-square-meter garden features an 80-year-old weeping cherry tree that is truly a sight to behold when in full bloom.
