Hiraodai, Karst plateau in Kitakyushu, Japan
The limestone plateau extends across 320 hectares of land, featuring white limestone formations, underground caves, and numerous sinkholes across the landscape.
The limestone bedrock formed 340 million years ago from marine organisms near the equator before tectonic movements transported it to its current location.
The plateau houses the Hiraodai Nature Observation Center, which educates visitors about local geological features and traditional agricultural practices in the region.
The site includes three accessible caves - Senbutsu, Mejiro, and Ojika - with guided tours available from 9:00 to 17:00 throughout the year.
The plateau contains approximately 400 dolines, natural depressions in the limestone surface that local farmers previously used as agricultural fields.
