Okoshiki Beach, located in Uto City, Kumamoto Prefecture, is one of the most picturesque beaches in Japan famous for its beautiful mud-flats and vanishing causeway. Being a very flat beach, the patterns left by the ocean at low tide cause for an almost rippling effect on the sand which along with the sunset in the background makes for breathtaking scenery. So make sure you have your camera at the ready for this beautiful beach spot!
