History

Chatsubomigoke Park, formerly called the Kusatsu Mine, operated as a mine extracting limonite and iron alum stone precipitated through the volcanic activity of Mount Kusatsu-Shirane. Located in a former village now part of Nakanojō, the site continued after mining ended as a place where a mineral spring remains and Jungermannia vulcanicola moss grows naturally under the area's distinctive water conditions.
