Volcanic healing escape

Tucked between Lake Mashu and Lake Kussharo in Akan-Mashu National Park, Kawayu Onsen is a quiet hot spring village known for its distinctive, naturally acidic waters said to have powerful therapeutic properties. Set against volcanic landscapes and dense forests, it’s an ideal retreat for those seeking rest and reflection. Visitors can enjoy peaceful walks through steaming sulfur vents at Mount Iō, soak in outdoor baths surrounded by nature, or explore the crystal-clear lakes nearby. With its deep connection to the land, Kawayu offers a raw, elemental side of Hokkaido.
