The Harukaze-class Destroyer was the first indigenous post-World War II Japanese destroyer class. Its main mission was anti-submarine warfare.

Almost all equipment was supplied from the United States according to the U.S. and Japan Mutual Defense Assistance Agreement. Sensor systems on-board was standard equipment in the U.S. navy at that time, for example, the AN/SPS-6 air-search radar, the AN/SPS-5 surface-search radar, the QHB search sonar, the QDA attack sonar.

Three 5"/38-caliber Mk.12 guns were mounted on Mk.30 single mounts, and controlled by a Mk.51 director. But the JMSDF wasn't satisfied with performance of the director, so latter, Mk.51 was replaced by the Swedish advanced GFCS developed by Contraves (Harukaze) or American Mk.57 (Yukikaze). At the same time, K-guns and depth charge racks were reduced by half and replaced by Mk.32 lightweight torpedoes with two Mk.2 over-the-side launchers.
