Japan has a defense complex, it has different names. Anything labled "Heavy Industries" is often defense or aerospace related.

Mitsubishi Heavy Industries, Hitachi Heavy Industries, etc.

Airplanes made of aluminum aren't that heavy....

Japan also has 900 tons pf plutonium from reactors. Now, almost all of this is unusable a weapons material because of excessive Pu 240, but it is likely that there is some weapons grade material somehwere. Japan also enriches uranium, usually to the 20-40% U235 level for reactors, but it is easy to re-arrange the gas centrifuge cascades to produce the 90 %
level for weapons. There is enough enrichment capacity that Japan could produce enough 90% U 235 for many bombs each year.

Japan also has enough physiscs knowledge to produce both boosted fission devices, taking yield to the 50-100 kiloton level, and very likely simple thermonuclear devices, with yields in the 100 kt to 1 megaton range (maybe ?)

Airplane, rockets, electronic guidance , and system integration and testing are all within thier capability.

Biggest missile technology gap might be re-entry vehicles knownledge - hard to acquire without some VERY obvious tests.
They have extensive knownledge of high temperature ceramics.

They can buy much military technology from Russia, Israel, UK, France, South Africa, Germany and possibly China.
