With the start of the Korean War in 1950, the base was turned over to the Japanese Coastal Safety Force, the immediate predecessor to the JMSDF. With the final withdrawal of American forces from Hachinohe in 1956, the base was officially designated JGSDF Camp Hachinohe.
The Japan Maritime Self-Defense Force (JMSDF) established a presence from 1957, and the JMSDF Hachinohe Air Wing was renamed Fleet Air Wing Two in 1961. The wing was initially equipped with LockheedP-2 Neptune, later transitioning to Kawasaki P-2J Neptune aircraft.
In 1963, American authorities banned civilian air traffic to Misawa Air Base, citing safety and security reasons, and commercial air operations were transferred to Hachinohe. In 1963, Air Patrol Squadron 2 was established and reequipped with P-2J Neptune aircraft in 1971. The squadron transitioned to the P-3C Orion in 1985. With the re-opening of Misawa Airport in 1975, commercial operations were transferred back to Misawa. In an administrative reorganization in 2008, UH-60J helicopter operations were transferred to JMSDF Ōminato Air Station.
