Fugaku Fuketsu is a horizontal lava tube, 201 m long, and the ceiling rises to 8.7 m in places, so most of the 15-minute walk is upright and fairly level. It stays at about 3°C, and ice pillars stand near the back even in August. The rock is dark basalt, with shelves along the walls where the lava level once stood. Until the early Showa period, people kept silkworm eggs here, where the cold held back their hatching. Like Narusawa, it has been a national natural monument since 1929. The cave sits in Aokigahara, the forest that grew over the 864 lava flow, and the Tokai Nature Trail passes the entrance; the operator runs guided walks through the forest that need booking. Without a car, timing is the catch: the Blue Line leaves Kawaguchiko only five times a day, and the last bus back from here goes at about 17:00. Narusawa Ice Cave is about 800 m east, and Saiko and Lake Shoji are a short drive west. ## FAQ ### Should I visit the Wind Cave or the Ice Cave? The Wind Cave is level and roomy, about 15 minutes, and fine for children and older visitors. The Ice Cave is shorter but almost all stairs with a 91 cm ceiling, and it turns away children under 4 or under 100 cm. They are 800 m apart and each costs 350 yen, so many people do both. ### How much is entry? 350 yen for adults and 200 yen for elementary school children and younger. Tickets can also be bought in advance on a smartphone through the link on the official site, which lets you skip the ticket queue. ### Is there anywhere to eat? Yes. The Mori no Eki Fuketsu building by the entrance has a food corner and a shop selling local food and souvenirs. --- Source: Fugaku Wind Cave — Japan Voyage
