Goshogake Onsen

Goshogake Onsen is a remarkable volcanic hot spring complex deep in the mountains of Akita Prefecture in northern Tohoku, Japan, located within the Towada-Hachimantai National Park in an active geothermal zone characterized by boiling mud pools, fumaroles, steam vents, and vivid volcanic deposits. The bicarbonate-rich and highly acidic thermal waters, emerging at high temperatures from the active hydrothermal system, are used in a traditional onsen facility that allows visitors to experience some of Japan's most powerfully concentrated geothermal energy in a wild mountain setting. The adjacent 'natural greenhouse' — a self-guided boardwalk trail through the active geothermal field with its bubbling mud calderas and steaming hot spring pools — is a rare opportunity to observe raw volcanic hydrothermal activity at close range. Goshogake Onsen is one of Tohoku's most extraordinary natural thermal experiences, combining powerful geothermal bathing with the haunting landscape of an active volcanic wilderness.
