Hagushi bay was the primary unloading point for American supplies during the invasion of Okinawa during World War II. The bay, at the mouth of the Bishi River (now called Hija River), was the dividing line between the First and Sixth US Marine divisions, which landed on the Hagushi beaches to the north, and the Seventh and Ninety-sixth US Army divisions which landed south of the river's mouth. In the seven-day campaign of aerial and naval bombardment which preceded the 1 April 1945 landings, Japanese beach defenses and shipping at the Bishi River's mouth were heavily bombarded, and US Navy frogmen swept the Hagushi beaches of thousands of mines and nearly 3000 wooden posts. The beach landings were unopposed by the Japanese Army aside from scattered artillery and sniper fire, and by nightfall on 1 April 1945, 60,000 American troops were ashore. [1]
It is located in Yomitan, Okinawa. The north side of the mouth of the river is now a public beach called Toguchi Beach.
