JS Wakasa (AGS-5104) is a Futami-class oceanographic research ship for the Japan Maritime Self-Defense Force.

Construction and career

[edit]

Wakasa was laid down on 21 August 1984 and launched on 21 May 1985 by Hitachi Zosen Corporation Maizuru Shipyard. She was commissioned on 25 February 1986 and was incorporated into the Marine Service Corps and deployed in Yokosuka.

The fishing boat Kiyotoku Maru (7.3t), whose hull was cut off after colliding with JS Atago on 18 February 2008, was towed by Muroto.[relevant?]

On 18 September 2009, Naoko Matsuo, 3rd class Kaisa (at that time), was appointed as Wakasa's captain, becoming the first female captain of the Maritime Self-Defense Force.[1]

In response to the Great East Japan Earthquake caused by the 2011 off the Pacific coast of Tohoku Earthquake, Wakasa departs from Yokosuka for disaster relief. At 2:42 pm on March 21, she shipped relief supplies to the Ishinomaki City Oshika General Branch. She returned to Yokosuka on 28 March.

On 1 December 2015, the Oceanographic Command Group was reorganized into the Oceanographic Command and Anti-submarine Support Group. Wakasa was incorporated into the 1st Oceanographic Observatory, which was newly formed under the same group.

Wakasa is planned to be decommissioned and replaced by JS Akashi once the latter is commissioned in March 2026.[2][3]
