Nanking Massacre Memorial Day

The National Memorial Day for the Victims of the Nanjing Massacre is a national memorial day observed in China on 13 December annually in honor of the Chinese victims of the Second Sino-Japanese War. The observance draws attention to Japanese war crimes during this period. It was established in 2014 by the Standing Committee of the 12th National People's Congress.

Starting on 13 December 1937, soldiers in the Imperial Japanese Army carried out the Nanjing Massacre in Nanjing, the capital of the Republic of China. The massacre lasted into January 1938 and killed numerous people (hundreds to hundreds of thousands according to Japanese publications, or over 300,000 according to most Chinese historians). This constituted a crime under international law, for which the perpetrators were tried in the International Military Tribunal for the Far East and the Nanjing War Crimes Tribunal after World War II.
