'''JS ''Wakasa'' (AGS-5104)''' was a [''Futami''-class](/source/Futami-class_oceanographic_research_ship) [oceanographic research ship](/source/oceanographic_research_ship) for the [Japan Maritime Self-Defense Force](/source/Japan_Maritime_Self-Defense_Force).
== Construction and career ==
''Wakasa'' was [laid down](/source/laid_down) on 21 August 1984 and [launched](/source/Ceremonial_ship_launching) on 21 May 1985 by [Hitachi Zosen Corporation](/source/Hitachi_Zosen_Corporation) [Maizuru](/source/Maizuru) Shipyard. She was [commissioned](/source/Commissioned_(ship)) on 25 February 1986 and was incorporated into the Marine Service Corps and deployed in [Yokosuka](/source/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 {{JS|Muroto|1979|2}}.{{Relevance inline|date=October 2025}}
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.[{{Cite web|date=2009-10-22|title=朝雲ニュース|url=http://www.asagumo-news.com/news/200910/091015/09101504.htm|access-date=2021-05-22|archive-url=https://web.archive.org/web/20091022171636/http://www.asagumo-news.com/news/200910/091015/09101504.htm|archive-date=22 October 2009}}]
In response to the [Great East Japan Earthquake](/source/2011_T%C5%8Dhoku_earthquake_and_tsunami) 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](/source/Ishinomaki) 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.
When {{JS|Akashi}} was commissioned in March 2026 to replace ''Wakasa'',[{{cite news|url=https://www.ships-net.co.jp/%E2%96%A0%E4%BB%A4%E5%92%8C%EF%BC%94%E5%B9%B4%E5%BA%A6%E9%98%B2%E8%A1%9B%E4%BA%88%E7%AE%97%E3%81%AE%E6%94%BF%E5%BA%9C%E6%A1%88%E6%B1%BA%E5%AE%9A/ |title=令和４年度防衛予算の政府案決定 |language=ja |date=24 January 2022 |trans-title=Government Decision on FY2022 Defense Budget |work=Ships of The World |archive-url=https://web.archive.org/web/20220529054737/https://www.ships-net.co.jp/%E2%96%A0%E4%BB%A4%E5%92%8C%EF%BC%94%E5%B9%B4%E5%BA%A6%E9%98%B2%E8%A1%9B%E4%BA%88%E7%AE%97%E3%81%AE%E6%94%BF%E5%BA%9C%E6%A1%88%E6%B1%BA%E5%AE%9A/ |archive-date=29 May 2022 |access-date=24 October 2025}}][{{cite news |url=https://trafficnews.jp/post/551745 |title=16年ぶり！ 新たな自衛艦「あかし」進水 ミサイルも大砲もないけど超重要な存在 どこに配備？ |date=29 May 2025 |language=ja |trans-title=First in 16 years!
