In 1951, General Matthew Ridgway, Supreme Commander of the Allied Forces, proposed to lend a patrol frigate (PF) and a landing support boat (LSSL) to Japan under Allied occupation. In response to this, on April 26, 1952, the Coastal Safety Force was established within the Japan Coast Guard to serve as a receiver for these warships and as the base of the future Navy. Then, with the establishment of the National Safety Agency on August 1, the same year, the Coast Guard absorbed the route enlightenment department of the Japan Coast Guard and was reorganized into a security force, and together with the National Police Reserve (later the National Safety Force), which is a land unit, of the National Safety Agency.^[1]

Of the rented vessels, all 18 PF vessels were delivered in 1953 and commissioned as comb-type guard vessels, which later became the starting point for the development of the Maritime Self-Defense Force escort vessels. In the budget for 1952, which is the year when the guards were established, the construction of support vessels (water vessels, heavy oil vessels, etc.) to improve the operational base of these guard vessels was prioritized, and the construction of combat ships was not carried out. Although domestic construction of security vessels began in 1953, the construction in the same year was two 1,600-ton instep security vessels (Harukaze class) and 1,000-ton B-type security vessels (JDS Akebono and Ikazuchi class) It was fastened to 3 ships.^[2]

After that, the US-Japan Ship Loan Agreement was signed on May 14, 1954, and two Livermore-class destroyers and two Cannon-class destroyer escorts were to be rented. This type is the one that recommissioned this Cannon class. The Livermore class became the Asakaze-class destroyer.
