Reviews Summary

Visitors find Narusawa Ice Cave a unique and memorable stop near Mount Fuji, offering a refreshing escape from the heat with its impressive ice formations and lava tube passages. While short, the adventure through narrow, slippery tunnels is a highlight. Some note the limited ice in warmer months and the need for caution due to the terrain.

"Cheap but cheerful cave experience amongst beautiful naturescape.
Visit during winter to see ice pillars. We visited in autumn & signs pre-warned ice pillars had melted, so we knew what to expect. Still went for the experience!
Steep but short climb down 21m. Cold, so prepare accordingly. Watch your head for low hanging rocks. A short section where we had to pretty much crawl through - a unique experience! Take as long as you like, but approx 10min round trip.
1.4km trail walk (30min) to Wind Cave - can purchase combo tickets. Well worth it for something different and a bit of a nature walk. But you can also drive there."

"A unique and memorable stop near Mount Fuji. The Narusawa Ice Cave takes you through narrow lava-tube tunnels with impressive ice formations that stay frozen all year. It’s short (so take your time and make the most of it) but fascinating, about a 20-minute walk through chilly, dim passages that feel like an underground adventure.

It can be slippery and tight in spots, even a section to almost crawl, so wear good shoes and a light jacket. The staff are friendly, and signs are available in English and Japanese. Great to pair with the nearby Fugaku Wind Cave for a full experience. Easy to access by car, plenty of parking onsite and leading into, or local bus, and well worth the visit if you’re exploring the Fuji Five Lakes area.

There is a gift shop attached where you can also purchase food items.

We also visited the Wind Cave, this experience was a little more comfortable, ticket entry can be purchased for both caves at each site."

"Located in the Aokigahara Forest at the northwestern foot of Mt. Fuji, Narusawa Ice Cave is a small lava tube formed about 1,150 years ago during one of Fuji’s eruptions. The temperature inside remains around 0–3°C throughout the year, allowing impressive ice formations to persist even in summer.

The walking path is short — about 150 meters — leading down a narrow, slippery tunnel with solidified lava walls and a distinct chill in the air. Two main chambers display preserved ice: one illuminated with soft blue light, the other protected behind metal bars.

A full visit takes around 10–15 minutes, and while it’s interesting from a geological perspective, the experience can feel brief — essentially a short descent to view the ice and back. It’s best to buy a combined ticket that includes Fugaku Wind Cave nearby, for a more complete and rewarding visit to the Fuji Five Lakes Geopark area"
