Kuroiwa Burial Caves

Kuroiwa Burial Caves is a rock-cut tomb complex with more than 200 chambers carved into tuff cliffs in Yoshimi. Each chamber features a small square entrance that opens to larger interior spaces designed for burial and ceremonial purposes.

The site originated during the Kofun period when families began carving tombs directly into cliffs rather than building burial mounds. Excavations in the late 1800s revealed artifacts including jewelry and mirrors that shed light on daily life from that era.

The chambers reveal how families in ancient times honored their dead through carefully arranged burial spaces with personal items. Walking through the caves, you notice the raised platforms where coffins once rested, showing deep care in funeral customs.

The caves are reachable on foot from the nearest train station and can be explored without special equipment. Bringing a flashlight is helpful since some chambers are dark, and sturdy shoes are recommended for walking on uneven ground.

A rare yellowish-green moss grows around the cave entrances and glows faintly in dim light. This special plant was so valued that the entire site received protected status in 1928 as a Natural Monument.
