Oni no Sentakuita Rocks

The beautiful Unosaki Beach has been designated as one of Japan’s Hundred Best Beaches. Because the coast is so shallow, you can see the winding shape of the sea floor when the tide is out. The shape we see today was formed 10 million years ago when the geological stratum on the sea floor rose out of the water and the softer layer was worn away by the waves, leaving only a hard layer behind. Because of this, you can find fossilized fish bones and scales here. The shape of the sea floor gives the beach its nickname, Oni no Sentakuita Rocks.
