Limestone cave where you can sense the heartbeat of the Earth

Gujo Hachiman is located in the deep mountains of Gifu, where is famous as a famous water town. Water supply of the town is from the karst topography of the limestone layer spreading in the mountains. There are many limestone caves in the town from the Nishi-wara area to Akuda. Hundreds of millions of years ago, surrounding area was a shallow tropical seabed. Coral breeding on the seabed created hundreds of meters of limestone. Limestone layer was melted by the inflow of rainwater and groundwater due to repeated crustal movements, resulting in the formation of complex limestone caves divided into multiple layers.
