Narusawa Ice Cave

Overview

Narusawa Ice Cave is a lava cave located in Narusawa Village, Yamanashi Prefecture, and designated as a national natural monument. It was formed over 1150 years ago, in 864 AD (Jogan 6), by the cooling lava flow from the eruption of Mount Fuji's parasitic volcano, Nagao-yama. The cave maintains a low temperature year-round, offering a refreshing experience even in summer. At "Kinos Ike" (the Pond of Trees), 21 meters underground, you can see ice pillars and basalt lava formations. Narusawa Ice Cave is not only a place to experience the natural beauty sculpted by Mount Fuji's eruption but also a geologically significant site. In summer, many tourists visit seeking coolness, enjoying a refreshing space while experiencing the grandeur of Mount Fuji's nature. Narusawa Ice Cave is a recommended sightseeing spot where you can feel the history and nature of Mount Fuji.
