(日本の歴史授業が無視するもの)
There was one page on other events leading up to the Sino-Japanese war in 1937 - including one line, in a footnote, about the massacre that took place when Japanese forces invaded Nanjing - the Nanjing Massacre, or Rape of Nanjing.
There was another sentence on the Koreans and the Chinese who were brought to Japan as miners during the war, and one line, again in a footnote, on "comfort women" - a prostitution corps created by the Imperial Army of Japan.
There was also just one sentence on the atomic bombings of Hiroshima and Nagasaki. (quote BBC)
