Geometric formations of countless hexagonal rocks spreading across the coastline

About this spot

This is a rare natural phenomenon where countless hexagonal rocks, formed when lava cooled and solidified, spread across the coastline like a laid-out tatami mat. At low tide, you can walk on the rocks for a close-up view, and the regular geometric patterns are designated as a Natural Monument of Okinawa Prefecture. It's conveniently located along with other northern Kumejima tourist spots like Meefugaa.

Tips

The appearance changes significantly depending on the tide. It's recommended to check the low-tide schedule in advance. Rock surfaces are slippery, so wear sturdy shoes rather than sandals.
