Japan and Germany, two of the war criminal nations of WWII, are very different. Unlike Germany that apologized for their crimes to the international community and built their trust through honesty, Japan is denying to repent for their shameful test and rationalizing their distortion of the history.
Japan is restoring the use of the Rising Sun Flag, a symbolism of invasions by Imperial Japanese Army. This is basically the equivalent of Germans using the Nazi Germany Flag. This is proof that Japan still craves the desire for the failed Japanese imperialism. It's almost as if Japan is reenact the past invasions anytime soon. We can see Japan's fascism from their arguments that Korea's Dokdo is Japanese territory.
Japan still covets for other country's territory. Japan will not be welcomed in the international community if it persists its efforts to distort the past and refuse to apologize for its past crimes.
