History

Background

With the surrender of Japan on 2 September 1945, the Japanese army was disarmament and dissolved. In the Navy, the Imperial Japanese Navy General Staff was dissolved, and the Ministry of the Navy, which was the military administration department, was reduced and reorganized into the 2nd Ministry of Demobilization, which took over some operations such as demobilization and route enlightenment. Furthermore, with the progress of demobilization, in 1946, it was integrated with the 1st Ministry of Demobilization (Ministry of the Army), and the Demobilization Agency (2nd Demobilization Agency), which is an external agency of the Cabinet, and later under the direct control of the Prime Minister's Office. After that, it became a part of the Ministry of Health and Welfare (Demobilization Bureau).

However, even after the war, the need to open the route for mines laid by both the US and Japanese forces during World War II was serious. For this reason, the Navy's minesweeping unit, which once stopped the minesweeping work and dismantled, but was immediately reorganized as the Minesweeping Division of the General Affairs Bureau of the 2nd Ministry of Demobilization on September 18, and the work was resumed. After that, it changed to the Minesweeper Division of the General Affairs Department of the 2nd Demobilization Agency and the Minesweeper Division of the Demobilization Agency. On the other hand, as the deterioration of offshore security became more serious due to the demobilization of the Japanese Navy, in 1946, the Japan Coast Guard became a law enforcement agency under the Ministry of Transport, incorporating these former Navy-derived sweeping units. It was installed. However, at the time of its establishment, in response to instructions from the GHQ Civil Affairs Bureau in consideration of the backlash from the Far Eastern Commission against the armed Japan Coast Guard ships, strict restrictions were imposed on displacement, armament, and speed in order to clearly indicate that the patrol boat was not for military use.

In October 1950, after receiving an informal consultation regarding the (PF) loan from the US Far East fleet, former Admiral Kichisaburo Nomura, former Admiral Zenshiro Hoshina, and former Demobilization Agency Second Rehabilitation Bureau, an informal study of the Navy's revival was undertaken, centered on Navy personnel. On 19 October 1951, at a meeting between Prime Minister Shigeru Yoshida and General Matthew Ridgway, Supreme Commander for the Allied Powers (SCAP), 18 frigates (PF) and 50 landing support crafts (LSSL) were proposed. The lending proposal was officially made, and Prime Minister Yoshida accepted it on the spot. Then, in order to accept these vessels and establish an operation system, the Y Committee was set up as a secret organization under the direct control of the Cabinet and examined it. The members of the Y Committee were appointed by former Navy personnel and the Japan Coast Guard Officer, and were in close cooperation with the US side. As a result of the examination by the Y Committee, these vessels will be centrally operated by a dedicated department set up within the Japan Coast Guard, separately from other patrol vessels, just before the San Francisco Peace Treaty comes into effect. On 26 April 1952, the Coast Guard was established at the Japan Coast Guard.

Equipment

Originally, the predecessor Coastal Safety Force was an organization that was established to centrally operate the ''Tacoma''-class frigate (PF) provided by the United States, but it took time for diplomatic and political procedures and ship maintenance. The official delivery was not in time for the Coastal Safety Force era, and the ship was only undertaken for storage (borrowing) after the maintenance was completed. At the time of the inauguration of the Coastal Security Force, there were only 76 vessels, including 4 patrol frigates (PF), 2 Landing Craft Support crafts (LSSL), and minesweepers under the jurisdiction of the Japan Coast Guard.

The US-Japan Ship Lease Agreement came into effect on 27 December 1952, and the first delivery ceremony was held on 14 January 1953. Since then, 18 PFs and 50 LSSLs have been lent 11 times until December 23. These were called guard ships and were all named after flowers. In April 1953, the 1st Fleet Group was formed by these ships.

In order to solve this shortage of ships, a new domestic ship construction plan was drafted in the 1953 plan, and construction of two A-type guard ships (later ''Harukaze''-class escort ships) and three B-type guard ships ( ''Akebono'' / ''Ikazuchi''-class escort ships). Has been decided.

However, because domestic ships were not completed immediately, the Japan-US ship loan agreement was signed on 14 May 1954, and () and () were signed. (), (), etc. would be rented. Although it was not until the Maritime Self-Defense Force received these rented ships, it became the core of the Maritime Self-Defense Force's strength at the time of its establishment, and it was in a position as a de facto navy.

The aircraft first received was a Bell-47D helicopter at the Susaki Heliport on 6 August 1953, and then received a total of four aircraft. They also bought three S-51s and two S-55s. These rotorcraft were deployed to the Tateyama Air Group. For fixed-wing aircraft, they purchased a training aircraft and deployed it to the Kanoya Air Group.

The guard ships were supposed to display the national flag and the guard flag, but the guard flag was enacted on 8 November 1952 and was hoisted until the self-defense ship flag was enacted.
