I can see how North Korea copied Japan's militarism and called it "Songun" as a North Korean version of it.
But Japan is much more superior to North Korea in terms of being cool and having good songs, especially Imperial Japan.
I thought it just had Battotai and thats it, but now I see that Imperial Japan had lots of songs which are just awesome, so no wonder people wanted to fight for the Emperor.
I think Imperial Japan could have won WW2 if it didnt surrender, but it chose the more peaceful way to conquer world by anime.
It was a brilliant strategy approved by the Emperor.
