芥屋の大門

The Keya no Ohto basalt cave stretches 90 meters deep into the cliff face, with a height of 64 meters and an entrance width of 10 meters.

The columnar basalt formations of Keya no Ohto developed through volcanic activities millions of years ago, creating distinctive hexagonal and octagonal patterns in the rock.

Local fishermen from the Keya port maintain maritime traditions by operating sightseeing boats that allow visitors to experience the cave's grandeur from March to November.

Visitors can reach the cave by taking a bus from Chikuzen-Maehara Station to Keya bus stop, followed by a 10-minute walk to the boat departure point.

The cave structure represents one of Japan's three largest basalt caves, featuring natural geometric patterns that extend from the sea level to the cave ceiling.
