From August to September 2012, a series of anti-Japanese demonstrations were held across more than 100 cities in China.^[1] The main cause of the demonstrations was the escalation of the Senkaku/Diaoyu Islands dispute between China and Japan around the time of the anniversary of the Mukden Incident of 1931, which was the de facto catalyst to the Japanese invasion of Manchuria, culminating in a humiliating Chinese defeat and a decisive Japanese victory vis-à-vis total consolidation and annexation of Manchuria. Protesters in several cities later became violent and local authorities began arresting demonstrators and banning the demonstrations.

The Senkaku Islands (Diaoyu Islands) are offshore islands near Taiwan, and have been a subject of territorial dispute between the governments of China, Taiwan and Japan.^[2] Prior to the demonstrations, there were many cases of protests over the sovereignty of the islands, most notably those in China in 2005. September 18 marks the anniversary of the 1931 Japanese invasion of Manchuria, the memories of which fuel anti-Japanese sentiment in China.^[3]

After the 2010 Senkaku boat collision incident, China stopped exporting rare earths to Japan.^[4]

On 16 April 2012, Tokyo's prefectural governor Shintaro Ishihara publicly announced his decision to let Tokyo Municipality purchase the island from its private owner.^[6]

On 4 July 2012, three Japanese coast guard boats made an official inspection of a Taiwanese ship near the disputed island.^[5] After the inspection, Japanese coast guard and Taiwanese coast guard stood face to face.^[5]

On 7 July 2012, Japanese prime minister Yoshihiko Noda expressed his consideration for the Japanese government to buy the disputed islands. The Chinese government angrily protested; Ministry spokesman Liu Weimin retorted "No one will ever be permitted to buy and sell China's sacred territory".^[7][8]

On 15 August 2012, activists from Hong Kong sailed to, and landed on one of the disputed islands, but were stopped by the Japan Coast Guard. Seven activists jumped from the ships to swim ashore, five of whom reached the island; the other two turned back to the ships. The activists and their ship were detained by Japanese authorities.^[9] The detained activists were deported two days later.^[10]

After the detainment of Hong Kong activists by the Japanese Coast Guard, netizens in mainland China called for a nationwide protest against Japan on 19 August.^[12][13][14]

In Beijing, citizens began protesting in front of the Japanese embassy on 15 August. On the morning of 19 August, a crowd of demonstrators gathered and held placards bearing phrases such as "Return us the Diaoyu Islands" and "Japan must confess her crimes".^[14]

In Shenzhen, protesters marched down the streets chanting slogans such as "Defend the Diaoyu Islands" and "Smash Japanese Imperialism", called for the boycott of Japanese goods and for the government to retake the islands.^[15][16] In the process, many protesters tore up Japanese flags, smashed Japanese-branded cars^[17] and vandalized shops selling Japanese goods;^[18] rocks were hurled at a Ramen shop.^[19] The protests lasted until about 2pm.^[20] According to Sing Tao Daily, the government sent in large numbers of armed police, who called for an end to the violent protests, began driving the protesters away and detaining several over-reacting protesters.^[21]

The anti-Japanese protests were occasionally exploited by protesters who sought to criticize the Chinese government. Such demonstrations included marching with posters of the late Chinese leader Mao Zedong—perceived to be more assertive on issues of sovereignty than current leaders, as well as signs about corruption, food safety, and income inequality.^[22] Supporters of the ousted anti-capitalist leader Bo Xilai also had a showing during the protests.^[23]

There were also protests of varied intensities in other major cities such as Jinan, Qingdao, Guangzhou, Taiyuan, Shenyang, Changchun, Harbin, Chengdu and Hangzhou. There were police officers maintaining order at the scenes to prevent incidents of violence.^[14]
