Sandanbeki, Coastal cliff in Shirahama, Japan
The Sandanbeki cliff extends for 2 kilometers along the Pacific coast, rising 60 meters above the ocean with three distinct rock layers.
During the Heian period, the Kumano naval forces utilized the caves beneath the cliff formation as concealed harbors for their vessels.
The cliff area contains designated viewing platforms where local fishermen traditionally monitored incoming ships and observed fish movements in ancient times.
Visitors can access the underground caves via an elevator that descends 36 meters below ground level to explore the marine-eroded caverns.
The cliff features a designated romantic spot with pink mailboxes and metal locks attached to heart-shaped monuments by couples expressing their commitment.
