'''JDS ''Chihaya'' (ASR-401)''' was a [submarine rescue ship](/source/submarine_rescue_ship) of [Japan Maritime Self-Defense Force](/source/Japan_Maritime_Self-Defense_Force).

== Development and design ==
The [Japan Maritime Self-Defense Force](/source/Japan_Maritime_Self-Defense_Force) (JMSDF) did not own a [submarine](/source/submarine) at the time of its inauguration, but in January 1955, it was announced that a submarine would be rented as an addition to the Japan-US Ship Lending Agreement signed in May 1954. The {{sclass|Gato|submarine|2}} {{USS|Mingo|SS-261|6}} was transferred to Japan and was recommissioned as JDS ''Kuroshio''. The JMSDF had been researching rescue ships from other countries, conscious of the need for rescue ships that can handle incidents from the time of acquisition of the submarine, but the first domestically produced ship {{ship|JDS|Oyashio}}. The construction of one ship was approved in the 1959 plan when (31SS) was under construction and ''Chihaya'' was ordered.<ref>{{Cite book|last=Mori|first=Tsunehide|title=12. Submarine Rescue Mothership and Rescue Ship, Continued Ship Mechanism Picture Book|publisher=Grand Prix Publishing|year=1991|isbn=978-4876871131|location=|pages=292–317}}</ref>

==Construction and career==
''Chihaya'' was [laid down](/source/Keel_laying) on 15 March 1960 at [Mitsubishi Heavy Industries](/source/Mitsubishi_Heavy_Industries), [Tokyo](/source/Tokyo) and [launched](/source/Ceremonial_ship_launching) on 4 October 1960. The vessel was [commissioned](/source/Commissioned_(ship)) on 15 March 1961. On 1 August 1962, the 1st Submarine Corps was newly formed and incorporated under the [Kure District Force](/source/Kure_Naval_District).

On 1 February 1965, the 1st Submarine Group was newly formed under the Self-Defense Fleet and was incorporated as a ship under direct control.

On 27 March 1985, due to the commissioning of {{ship|JS|Chiyoda|1983|6}}, the vessel's designation was changed to a special service ship, the ship registration number was changed to ASU-7011, and ''Chihaya'' was transferred to the Kure District Force as a ship under direct control. She was [decommissioned](/source/Decommissioned_(ship)) on 28 February 1989.
