小半鍾乳洞

This limestone cave in Mine City contains vast chambers and passages carved through rock over millennia. Visitors can walk through the interior on established paths with installed lighting to view the natural formations.

The cave gained official recognition in 1926 and later received designation as a Japanese Natural Monument. This status protected it as a site of national importance.

The cave has held regional importance for locals, who recognize its geological formations as natural landmarks central to the area's identity.

A visit is possible year-round thanks to stable conditions inside and good accessibility throughout. Wear comfortable shoes and bring a light jacket, as the interior stays cool regardless of the season.

The cave darkness is home to specialized animals that evolved without eyes or skin pigmentation over countless generations. These creatures offer a rare glimpse into how life adapts to extreme isolation and darkness.
