JS Ōyodo

[1] Ōyodo was laid down at Hitachi Zosen Corporation Osaka Shipyard on 8 March 1989 and launched on 19 December 1989.

[2] On 20 June 1991, the 39th Escort Corps was newly formed under the Sasebo District Force and was incorporated with JS Sendai.

In response to the 2011 Great East Japan Earthquake off the Pacific coast of Yokosuka caused by Tōhoku Earthquake, Ōyodo departed urgently to dispatch a disaster.

[3] On the morning of 20 March 2019, the high seas of the East China Sea (about 410 km, 250 mi south of Shanghai), North Korean-registered tankers Yu Son and Qinhuangdao confirmed that a small vessel with an unknown flag, which was labeled as Qinhuangdao City, North Korea, was performing what appeared to be a ship-to-ship transfer banned by a UN Security Council resolution.

Yu Son is a vessel designated by the United Nations Security Council North Korea Sanctions Committee as a target of asset freezing and port entry bans in March 2018.
