Very true. Japan committed tremendous atrocities against the Chinese during WWII. The Japanese made Hitler look like a choir boy, but people only remember Hitler. I’m sure that grudge hasn’t cooled one bit.
The Japanese decimated rebellious areas and conducted a number of post-battle atrocities. I'd say that's quite different from the Nazi policy of systematically seeking out Jews, Gypsies, Slavs and other disfavored groups for extermination. Life under Japanese rule was pretty simple - in any area that did not offer resistance, life went on as usual, subject to the privations of a war economy. This was why the civilian body count under Japanese rule was far lower than that under Nazi rule. The reason Japanese atrocities keep coming up in the news is because of the squeaky wheel principle - contrary to the stereotype, Europeans are stoic, whereas Asians are vocal. Japanese-style atrocities were pretty common among Asian armies. For instance, the massacre at Nanking was the third such city-wide massacre there - the first was in the 15th century during the Ming Emperor Yongle's usurpation of his nephew's throne and the second was in the 19th century during the Qing Emperor Xianfeng's recovery of the city near the end of Taiping Rebellion.
