On March 16, 1958, she was transferred to the 8th Escort Corps, which was newly formed under the control of the Yokosuka District Force, together with JDS Uranami. Since August of the same year, she has participated in the second Maritime Self-Defense Force practicing voyage.

She also participated in the 5th practicing voyage in 1961 and the 12th pelagic practice voyage in 1968.

On October 25, 1958, the 8th Escort Corps was reorganized under the 1st Escort Corps group.

On April 1, 1959, she was transferred to the 9th Escort Corps, which was newly formed under the 1st Escort Corps group, together with JDS Uranami.

During the special repair work from 1962 to 1963, the equipment was modernized, and the unequipped radio wave detector (ESM) NORL-1 was put in the back. Replaced equipment and search sonar with OQS-12 and attack sonar with OQY-2.

In July 1965, two depth charge projectors on the rear deck and two depth charge drop rails were removed, and equipped with Variable Depth Sonar (VDS) OQA-1.

On March 15, 1969, the 9th Escort Corps was reorganized under the 3rd Escort Corps group.

In 1970, the short torpedo launcher was removed, and work was carried out to strengthen the anti-submarine attack capability with two 68-type triple short torpedo launchers.

On February 1, 1971, the 9th Escort Corps was reorganized under the 4th Escort Corps, which was newly formed under the escort fleet.

On October 19, 1979, the Norwegian cargo ship Berge Oder moved northward in Tokyo Bay while typhoon No. 20 was evacuating off Kisarazu, about 16 km north of Futtsu Misaki. She broke 2 meters wide and 10 meters long 2 meters above the waterline on the side, but her crew was not damaged and returned to Yokosuka base on her own.

On March 30, 1983, she was changed to a special service ship and her ship registration number was changed to ASU-7004. She was transferred to the Kure District Force as a ship under direct control and her fixed port was transferred to Kure. In addition, she removed the 4-unit long torpedo launcher and VDS during the renovation work to the special service ship.
