Saiko Bat Cave
Saiko Bat Cave[Psycho Bat Announcer]
The largest lava cave at the foot of Mt. Fuji
This cave has a relatively large branch cave, with a total length of more than 350 meters, and is the largest lava cave at the foot of Mt. Fuji.
Inside the cave, stalactites and rope-shaped lava were formed on the inner surface of the cave when the lava that flowed out from the eruption of Mt. Fuji touched the outside air and solidified while releasing explosive components (gas).
Unlike other caves, the temperature inside the cave is not so cold in summer and warm in winter, so in the past, many bats lived as hibernation sites.
