Development

In June–July 1975, the Japan Defense Agency (JDA, now Ministry of Defense) examined the McDonnell Douglas F-15 Eagle as one of the 13 candidates for the replacement fighter of the F-104J/DJ Starfighter and F-4EJ Phantom II. A single-seat F-15C and a twin-seat F-15D were evaluated at Edwards AFB, and by December that year, the F-15 was announced the winner, with the government intending to purchase 187 F-15J/DJs. By April 1978, Mitsubishi Heavy Industries was designated as the primary contractor and licensing for the F-15C/D was achieved.

 for its first flight on 4 June 1980, and a subsequent cruise on 15 July to Japan. Additionally, 8 F-15Js were manufactured in large components and shipped to Japan for final assembly by Komaki of Mitsubishi, the first of these making its maiden flight on 26 August 1981 (serial number 12–8803). Companies divided the remainder share and produced it under license from 1981, with final assembly of aircraft performed by Mitsubishi.

In 1980, the Japanese government applied for access to advanced technology through the U.S.-Japan Forum (S&TF) but was rejected. The JDA and the DoD held an annual meeting about relaxation of the regulation after a program was started. In these meetings, the DoD official gave an answer that permitted access to initially prohibited technology of various types including composite material

Mitsubishi received F-15C/Ds MSIP and began with 1987 on F-15J/DJs to produce. Improvements included an uprated central computer, engines, Armament control set and added J/APQ-1 countermeasure set. Even the JASDF F-15s which already went into service caught the Japanese MSIP at the time of repair (IRAN). F-15J MSIPs were replaced from 1992 to F100-PW-220 (Also IHI-220 as); from 1996 to F100-PW-220E (Also IHI-220E as) was replaced. The difference in the appearance includes J/ALQ-8 ICS which an ICS antenna mounted under the intake. The J/APQ-4 RWR antenna position of F-15J/DJs is the same as F-15C/Ds, but the lens of F-15J/DJ MSIPs are black for white F-15C/Ds.

 follow-on with distinctive "barbed" forward fins. Japan has been trying to obtain an Advanced fighter (F-22 Raptor) to replace the F-15, but the search has been troublesome, and so the F-15J fleet is now being generally upgraded to keep the aircraft in fighting trim. In 28 July 2003, examination F-15J of the modernization did first flight (#928), and it was delivered to the JASDF Air Development Test Wing on 21 October 2003.

In 10 December 2004, the Japanese Government approved a Mid-Term Defense Program (MTDP) to perform modernization of F-15J MSIPs in five years by the cause of a new National Defense Program Guidelines. It appears the upgrade is being implemented in phases, but ultimately the refits will include a new ejection seat; replaced IHI-220E engines; more powerful processor; uprated electrical generation and cooling capabilities to support more avionics and the Raytheon AN/APG-63(V)1 radar.

As for the new MTDP approved on 17 December of the next year, the modernization retrogressed to 16 F-15Js. The MoD reduced it and they submitted 10 F-15Js modernization plan and restrained it.
