Fugaku Wind Cave, Lava tube in Japan
The Fugaku Wind Cave is a natural monument featuring ice walls and lava shelves.
Formed over millennia, the cave was once used to store silkworm eggs and seeds.
The cave's name, Fugaku, is another name for Mount Fuji, deeply connected to Japanese art and spirituality.
Visitors can enjoy a cool retreat during summer months, providing relief from Japan's humidity.
The consistently low temperatures preserve delicate ice formations year-round.
