The Narusawa Ice Cave lies about 1 kilometer east of Fugaku Wind Cave. It is a vertical, ring-shaped lava cave formed by lava flows during a Mt. Fuji eruption. The cave is about 150 meters long and forms a circular route. The average temperature inside is around 0°C, and ice pillars and ice walls can be seen year-round. It is designated a National Natural Monument. The route descends steep stairs to about 21 meters underground. Along the way is a low passage only about 91 centimeters high, which requires bending over or even crouching to pass through. The tour also passes sights such as the Ice Pond and Jigoku-ana (Hell Cave). The whole visit takes about 15 minutes. Admission is about ¥500, and a combined ticket with Fugaku Wind Cave is available. From Kawaguchiko Station, take the Lake Saiko Loop Bus for about 30 minutes to the Ice Cave stop. The cave floor is icy and slippery, so wear non-slip shoes and bring a jacket. Those with back or leg problems should consider skipping it.
