Narusawa Hyoketsu Ice Cave

This is a cave located at the eastern entrance to the “Aokigahara Jukai” (sea of trees) forest, and is one of the sightseeing spots within the Fuji Five Lakes area. In 864 A.D., when Mt. Nagao, a flank volcano of Mt. Fuji erupted, the red hot lava flow descended down between the ancient parasitic volcanoes creating this cave. The average temperature within the cave is as low as three degrees, and it is covered with ice year round. It was designated by the Ministry of Education as a Natural Monument in 1929.
