"Japan-bashing" (in the case of foreigners) or "self-flagellation"

[GoodTaste]

In 21st century Japan, the Nanjing Massacre touches upon national identity and notions of "pride, honor and shame". Yoshida argues that "Nanking crystallizes a much larger conflict over what should constitute the ideal perception of the nation: Japan, as a nation, acknowledges its past and apologizes for its wartime wrongdoings; or ... stands firm against foreign pressures and teaches Japanese youth about the benevolent and courageous martyrs who fought a just war to save Asia from Western aggression."[157] Recognizing the Nanjing Massacre as such can be viewed in some circles in Japan as "Japan-bashing" (in the case of foreigners) or "self-flagellation" (in the case of Japanese).

In addition to the valid interpretation provided by jutfrank, it may also imply that Japan is often mistreated in that way.
