MountainsAbout
Sekisuitei is a large hotel-style ryokan with its baths split across two separate wings: an indoor bath hall on the 8th floor of Kobushi-kan (辛夷館), and another on the 7th floor of Ginkyo-kan (銀杏館) that opens onto a rooftop bath overlooking the mountains. Both wings have a sauna, and five reservable private baths are available for a quieter soak. The spring water has a faint sulfur note. Day-use bathing is offered daily alongside overnight stays.
