The Yūshio class was a Japanese diesel-electric submarine class operated by the JMSDF. It was a second generation submarine, a development of the Uzushio class, incorporating a teardrop hull, with a resulting increase in underwater performance on the Uzushio class. Ten were built under the fourth defense plan in 1975 fiscal year. All vessels were retired with the decommissioning of Yukishio on March 7, 2008, and the completion of the Harushio class. JDS Akishio is on display at the JMSDF Kure Museum.
