Discovering the depths of the region
We should not forget that Mount Fuji is above all a volcano! Now dormant, Japan's tallest mountain has spawned numerous caves throughout its volcanic history. And although most of them are inaccessible today, some still delight tourists in the region. Discovery of three pearls hidden at the foot of the highest mountain in the country.
Narusawa Ice Cave
Located east of Aokigahara Forest , Narusawa Ice Cave is a natural ice cave that is over 1150 years old! Created following the eruption of Mount Fuji in 864 , it has long been used by the inhabitants of the region as a storage place for food or for medical equipment of the time.
With an average temperature of around 3°C , the Narusawa cave is now a popular tourist spot for caving enthusiasts. And many tourists come every day to admire its stalactites in the bluish light of the cavern spotlights.

FugakuFuketsu, the cavern of the wind
Located a stone's throw from Narusawa Cave, the Wind Cave is a pretty cave 201 meters long and 8.7 meters high. Like its neighbour, Fugaku Fuketsu Cave is a natural glacier born from one of Mount Fuji's eruptions.
Due to its very low temperatures (close to 0°C), it was still used until the 1950s as a storage place for silkworm cocoons that were produced in the area. These were then used to supply silk to kimono makers in the region.
