The Japanese were instrumental in helping to liberate China and ensure the creation of a unified China, India and Indonesia, and note that the development of Pan-Asianism allowed for the gradual independence of Korea and the souring of UK-Japanese relations. Having the militarists in power could actually see the creation of an Anglo-French-Japanese alliance.
With that in mind, the Korean independence movement may become more militant and aggressive if we see a militarist Japan. Possibly even some assassinations and car explosions. Good thing it didn't, so we only have the demonstrations in OTL history.
