Beaches near Tokyo

Tokyo offers a few beaches along its coast, but the water quality in the city is rather low, although it has been improving steadily over recent decades. Many more beaches are located within a 1-2 hour train ride in nearby Chiba and Kanagawa prefectures and on the Izu Peninsula. The beaches around Tokyo allow for sunbathing and swimming, and many are also good for surfing and windsurfing. Unlike the beaches in Okinawa, most beaches around Tokyo are not ideal for snorkeling and diving except for a few on the Izu Peninsula.
