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's Rising Sun Flag symbolizes Japan's imperialism that led to the massacre of 20 million people during the invasions by Imperial Japanese Army. The Japanese waved the flag and used the design in the athlete's uniforms at the Olympic games, which symbolizes world peace. This is the equivalent of Germans waving the Nazi Germany Flag during the Olympic games. This is an insult to human dignity.
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, revive imperialism, and refuse to apologize for its past crimes.
