A natural lava cave where ice remains even in the peak of summer
This lava cave was formed by eruptions from Mount Fuji and is a mysterious space where ice never melts even under the blazing summer sun. The temperature inside the cave stays consistently low throughout the year, and water that seeped in during winter remains frozen until summer arrives.
