The Japanese Phantom story started in 1968 with the order of 140 F-4Es all weather air defense fighters. Designated F-4EJ to identify the Japanese modification. The modifications included the absence of inflight refueling, ground attack capability and the possibility to carry the AGM-12 Bullpup. The aircraft were built in license by Mitsubishi Heavy Industries (MHI). Amongst the Phantoms build were 14 unarmed RF-4E reconnaissance aircraft.

As of 1984 a modification program was started to upgrade 96 F-4EJs to the F-4EJ Kai standard. (改, modified) The first F-4EJ Kai flew 17 July 1984 and was accepted by 306 Hikotai some 5 years later. 14 RF-4Es were also upgraded to the RF-4E Kai standard. The F-4EJ Kai modification included updated avionics, AN/AGP-66 pulse radar and ground attack capability. Also the ASM-1 anti-ship missile could be carried.

The JASDF also decided to convert 17 addition RF-4EJs as reconnaissance aircraft, these were also designated RF-4EJ Kai. The aircraft remained weapon capable, and also the under-nose Vulcan gun was still present.

The final phantom ever build, out of 5.195 aircraft, was a Mitsubishi build F-4EJ Kai 17-8440. It was rolled out of the factory on 21 May 1981.

The first two, American build, F-4EJs arrived at Hyakuri Air Base 25 July 1971. They were assigned to 301 Hikotai. During the F-4 peak, 6 squadrons operated the F-4EJ out of four air bases. 301 till 306 Hikotai. 1997-2001, 8 Hikotai also operated F-4EJs. 501 Hikotai was the sole squadron operation the RF-4EJs.

With the introduction of the F-35A into the JASDF, the days of the F-4EJs were numbered. 42 F-35As were bought and pilot training started at Misawa Air Base. 301 (and 302) Hikotai would take up the F-35 and will move to Misawa as well. 501 Hikotai ceased operations March 2020.
