About Sakieda Big Arch
Sakieda Big Arch is a boat-access topography dive on the western Ishigaki side, built around a large natural arch that throws sunbeams through the ceiling cracks when the light is right. Gentle currents, a shallow coral fringe, and schools of snapper make it a comfortable choice for newer and experienced divers, while winter-spring shrimp spawning adds a seasonal reason to plan the trip.
