JS Oyashio (SS-590) is the lead boat of the Oyashio-class submarines. She was commissioned on 16 March 1998.

Construction and career

Oyashio was laid down at Kawasaki Heavy Industries Kobe Shipyard on 26 January 1994 and launched on 15 October 1996. She was commissioned on 16 March 1998 and deployed to Yokosuka.

From 11 January to 10 April 2006, she participated in RIMPAC 2006.

On 10 January 2009, during a performance test 4.6 kilometres (2.9 mi) southwest of the Maritime Self-Defense Force Kagoshima Laboratory in Kirishima City, Kagoshima Prefecture, the Maritime Self-Defense Force's fishing boat 28th Kamemaru came into contact with the mast. A part of the stern of the fishing boat was damaged and dropped, but no one was injured. The fishing boat was chartered by the Maritime Self-Defense Force and was wary of other vessels from approaching during the performance test of Oyashio. On 8 December of the same year, the Kagoshima Maritime Security Department sent documents to the captain and three others on suspicion of the risk of a possible traffic incident. Furthermore, at around 0:15 pm on 17 June, the same year, during training on the Pacific Ocean about 28 kilometres (17 mi) east of Shiriyazaki, a cable for resource exploration (4.8 km) towed by the Agency for Natural Resources and Energy research vessel Shigen (10,395 tons) of the Ministry of Economy, Trade and Industry causes an incident that left some of the crew injured.

On 6 March 2015, due to the removal of the training submarine JDS Fuyushio, Oyashio's designation was changed to a training submarine on the same date, and the first training submarine under the direct control of the submarine fleet. After joining the corps, the submarine's fixed port was transferred to Kure.

From 19 March to 27 April 2016, she participated in the open sea practice voyage (flight) with the escort vessels JS Ariake and JS Setogiri. On 3 April, she entered Subic Bay on Luzon Island, Philippines, facing the South China Sea.
