Okoshiki Kaigan Beach, located in Uto City, Kumamoto Prefecture, is famous for its beautiful tidelands and causeway, and it is considered one of the most picturesque beaches in Japan. The beach is very flat, which results in ripple-like patterns in the tideland sand during low tide. During sunsets, the twilight glow shines on the ripples, creating breathtaking scenery popular among photographers and couples.
