The January 28 incident or Shanghai incident (January 28 – March 3, 1932) was a conflict between the Republic of China and the Empire of Japan. It took place in the Shanghai International Settlement which was under international control. Japanese army officers, defying higher authorities, had provoked anti-Japanese demonstrations in the International Settlement following the Japanese invasion of Manchuria. ^{[citation needed]} On January 18th, five Japanese Buddhists in Shanghai belonging to the Nichiren sect allegedly shouted anti-Chinese, pro-Japanese nationalist slogans in Shanghai.^[5] In response, a Chinese mob formed killing one monk and injuring two.^[5] In response, the Japanese in Shanghai rioted and burned down a factory, killing two Chinese.^[5] Heavy fighting broke out, and China appealed to the League of Nations. A truce was finally reached on May 5, calling for Japanese military withdrawal, and an end to Chinese boycotts of Japanese products. It is seen as the first example of a modern war waged in a large city between two heavily equipped armies and as a preview of what was to come during the Second World War.^[6]

The episode helped undermine civilian rule in Tokyo; Prime Minister Inukai Tsuyoshi was assassinated on May 15, 1932.^[7]
