Saburoiwa, Ama.

This draincover from the island of Ama in the Oki Islands shows a rock formation known as Saburoiwa. The design around the circumference shows dancers performing at the island's Kinnyamonya Matsuri.

Iwa means rock, and Saburo is a name traditionally given to the third son (Ichiro means first son). All of the Oki Islands have spectacular coasts, with many rock formations and towering cliffs.

On neighboring Nishinoshima Island are the basalt cliffs and formations of the Kuniga coastline that are part of the Daisen-Oki National park.

Tour boats explore many parts of the coastline in the Oki's, and there are also glass-bottomed boats to see the abundant sea life that inhabits the area.
