Japan and Germany were allies, they were called Axis.
I think Japan did good back then, but what the most of the soldiers did was awefull, they raped women, killed children.
But if 朝鮮民主主義人民共和国 wants to attack then i hope 日本 will blast them untill
朝鮮民主主義人民共和国 finally stops and come to the consideration that Japan is still a mighty country if they want with/without help from US.
