Ukon Danchi is a calm, shallow reef site located in the Kabira Area of Ishigaki Island. Suitable for beginners and snorkellers, the site features depths ranging from 8 to 14 metres with no current. Visibility typically spans 10 to 30 metres, allowing for clear observation of the reef structure. Access is exclusively by boat, and local facilities provide equipment rental and air fills. Divers should exercise caution regarding buoyancy to avoid contact with the substrate, as sharp coral and well-camouflaged stonefish are present. Jellyfish may also be encountered in the water column, so maintaining awareness of surroundings is essential throughout the dive.

Keep your eyes on the substrate and avoid contact with the bottom entirely, as stonefish are well camouflaged against rocky reef surfaces and pose a real risk to divers who are not yet confident with buoyancy. Booties with a hard sole are worth wearing for the boat entry and exit.
The site is not inside a marine protected area, making access straightforward.
