Narusawa Ice Cave
Narusawa Ice Cave is located at the eastern entrance to the Aokigahara Sea of Trees and is one of the most popular sightseeing spots in the Fuji Five Lakes area, attracting tourists throughout the year. These two tunnel-shaped caves were formed more than 1150 years ago (864) during the eruption of Mount Nagao, a side volcano of Mt.

Let's go exploring in a cave!

The pit-shaped caves are rich in natural undulations. Down the stairs... It is an adventure world full of curiosity! I'm excited to see what kind of world is out there... ♪

Before exploring: ・・・・

Let's check the precautions before entering the cave.

Be careful overhead.
It is slippery and there are many stairs, so it is dangerous to wear heels.
It is a 21-meter climb at a stretch. Please be careful for the elderly.
Children should not be carried on their backs or in their arms.
Animals are not allowed in the cave.
Ice is not always available all year round. Please be aware of this.

It is important for safe exploration!
*Please check our website for more information.

Finally, departure!

The temperature inside is an average of 3 degrees Celsius, and the icicles formed by frozen drops of water seeping from the ceiling are especially spectacular: they grow the most around April, and some years they can be as large as 50 cm in diameter and 3 m in height.
The cave is a ring-shaped pit with a total length of 153 m, a width of 1.5 m to 11 m, and a height of 1 m to 3.6 m. Because of its ring shape, visitors can enjoy the various faces of the cave by circling it once.

How about a souvenir?

The store sells original Narusawa Ice Cave products. Please pick one up to commemorate your visit. It will surely be a memorable experience.

We also recommend visiting Fugaku-kaze Cave!

About a 15-minute walk from the Narusawa Ice Cave we introduced here is the Fugaku Fubon Cave, a representative lava cave at the foot of Mt. With an average temperature of 3 degrees Celsius, it was used as a "natural refrigerator" in the days when refrigeration equipment was not available. The cave is a "side cave" that is easy for children and the elderly to explore. Why not visit this one as well?
