A secret bath near the summit of Mt. Hachimantai that only opens in late spring, once the snow-locked winter has passed. Three open-air baths — masu, taru, and iwa — sit scattered across a steam-shrouded geothermal field, where you can soak in pale-gray sulfur water flowing for 400 years and take in the stillness of the mountaintop.
