Seiryukaku is unique within Hachimantai, because it’s the only chloride in the region. The ancient waters Seiryukaku uses flow from deep underground, and are twice as salty as the ocean!  The result is a bath that’s very warm even compared to other hot springs.  It’s a perfect choice during the winter after an adventurous day outside!
