A full visit takes about 30–45 minutes. The interior route is 350 meters long with walkways, but the uneven ground and explanations may require extra time.

Formed by lava from Mount Fuji 1,150 years ago, it was used in the 19th century as a natural ice storehouse. Its name comes from the bats that lived there until the 1960s (they are no longer present today).

It is especially recommended in summer (June–September), when the inside stays at a cool 10°C. Avoid crowded weekends. Arrive before 3:00 PM to allow enough time.

It is not fully accessible: there are uneven stairs and narrow passages (minimum height 1.4 m). Wheelchairs are not allowed. Contact +81 555-72-0256 for specific needs.

A 5-minute drive away: Fuji Subaru Line 5th Station (views of Mount Fuji) and mysterious Lake Saiko with its twin caves.

Wear non-slip shoes, bring a flashlight (although there is lighting), and a light jacket (10°C inside). High heels are prohibited. There are no restrooms in the cave, so use the ones at the visitor center outside.
