The name means great tide. Oshio was an Asashio-class destroyer. Maizuru Naval Arsenal laid her down on 5 August 1936, launched her on 19 April 1937 and commissioned her on 31 October 1937.
At Pearl Harbor she was in Destroyer Division 8, Destroyer Squadron 2, escorting Kondo's Southern Force main body out of Mako as distant cover for the Malaya and Philippines landings. She escorted a Malaya troop convoy to Singora, put into Hong Kong on 5 January 1942, and then escorted convoys to Davao and the Ambon, Makassar and Bali and Lombok landings.
On the night of 19 February 1942 she was guarding the transport Sasago Maru off Bali when an Allied force attacked in the Battle of Badoeng Strait. She is credited with helping sink the Dutch destroyer HNLMS Piet Hein with a torpedo and with gunnery hits on the cruiser HNLMS Tromp and USS Stewart. She took medium damage and seven of her crew were killed. She was repaired at Yokosuka until the end of 1942.
In January 1943 she went to the Shortlands and made three runs to evacuate troops from Guadalcanal in early February. On 20 February, with her sister Arashio, she was attacked by USS Albacore. A torpedo flooded her engine room and killed eight crewmen. Arashio tried to tow her, but her keel was fatally damaged and she sank about 70 nautical miles northeast of Manus. She was removed from the Navy List on 1 April 1943.
