A few places that
might be potential targets...just suggestions...there's no canon list that I'm aware of, so it's pretty much up to each individual GM how they want to play it.
Mitsubishi Aerospace, Nagoya and Komaki (Manufactures licence built F15's and F2's (Japanese F16 variant))
Various shipbuilding facilities e.g. Nagasaki, Kobe (Japan was a major shipbuilder in the late 80's, building tankers, warships, container ships, etc)
Space Launch Facilities (I just had a quick skim of those but they all seem to have been operational in the late 90's)
