We have all heard about German, French, Italian, etc. resistance groups forming after the coming of Facism and/or invasions of their countries. However, I've never heard about any real resistance in Japan, China or Korea. It's easy to imagine there were groups in China and Korea, but were there any such groups in Japan?
Clarification, Are we talking active in combat type of resistance (IE free France)? Or are we talking about more subtle resistant groups that were more typical of German resistance (eg Die Weiße Rose)? I know that there were a few communist who were arrested before and during the war, but they would fall into a more passive resistance.
The Japanese Communist Party opposed the war but they were not militant about it. The party itself was banned in Japan at the time and many members were already in prison, due to the banning of labor unions and opposition of the Sino-Japanese war. A small number of Japanese communists worked as propagandists with aid of the Chinese communists.
