Hot springs in Mikuriga-ike

Japan's highest natural hot spring inn, perched at 2,410 meters above sea level on the Murodo Plateau of the Tateyama Kurobe Alpine Route in Toyama Prefecture. The water is a milky white acidic sulfur spring, 100% free-flowing and undiluted, drawing from the volcanic Jigokudani crater below. Open only from mid-April to late November. Getting here is an adventure in itself.
