Sea bathing until evening on a shore facing the Pacific
About this spot
Ohara Beach (大原海水浴場) opens on the Ohara coast in Shinden, Isumi City, and in 2026 it runs from Saturday, July 18 to Sunday, August 23, with swimming hours from 8:30 to 16:30. Its open sandy shore faces the Pacific Ocean, so families can spend their time freely, from splashing at the water line to playing in the sand. Being close to Ohara Fishing Port, it is also easy to combine sea bathing with port cuisine, which is part of its appeal.
