Hidden beneath the dense canopy of the Aokigahara forest, Narusawa Ice Cave is a fascinating natural lava tube formed over a millennium ago by Mount Fuji's volcanic eruptions. Visitors can navigate winding, low-ceilinged tunnels that maintain sub-zero temperatures even during peak summer months. Marvel at glistening icicles and towering ice pillars that naturally form from dripping groundwater. It offers an exhilarating and refreshingly cool underground adventure for explorers touring the Fuji Five Lakes region.
