Narusawa-mura, Japan

Narusawa Hyoketsu (Ice Cave)

A 70-foot-deep ice cave formed by lava from Mt. Fuji on the edge of Japan's "Suicide Forest." . 

All throughout Aokigahara, Japan’s so-called Suicide Forest, are underground caves that were formed by volcanic activity from the nearby Mount Fuji. If you ever go exploring, you may just fall into one.

One of the largest and most impressive of these lava caves is the Narusawa Hyoketsu, or Ice Cave. There are stairs leading down into the 70-foot-deep cavern and areas where you must crouch to get through. Once you reach the bottom, the ice is crystal clear and stunning, catching the color-changing light beautifully. 

The ice is there year-round, with large icicles growing throughout the cave sometimes up to 3 feet long. Located on the edge of the Suicide Forest, also called the Sea of Trees, Narusawa Hyoketsu is designated a Natural Monument of Japan.

Know Before You Go

Very easy to reach using the "sightseeing buses". Maps and affordable bus passes are available at Kawaguchiko station. Discounted entrance fee if you've purchased a bus pass (instead of paying for each ride separately). Very easy and cheap to visit if you were already planning to visit Aokigahara, as it is literally on the edge of the forest.
