Drawing source water seeping from the deposits of the former Kosan Mine, we have been heating it as mineral spring water and offering it to locals and visitors from outside the prefecture for over 60 years.Currently, we operate as a hot spring called 'Onseki-sen,' where the mineral deposits (ores) are laid at the bottom of the bathtub and heated. It warms your body thoroughly to the core, enhancing blood circulation and revitalizing the body.The water retains warmth well, promotes sweating, and is excellent for improving health. You can check the facility overview on our inn's website.Additionally, there is an Instagram icon at the bottom of the website, where you can view meals such as dinner and banquet dishes.
