Chinese fans subjected the Japanese team to intense booing at the Asia Cup Games held in China in August. They also made their disgust evident when Kimigayo, the Japanese anthem, was sung. Chinese fans vandalized Japanese Embassy cars in Beijing after the final match. These events sent shockwaves through Japan and the incidents were taken up by the foreign media.

The impact was not limited to the attention given to the radical actions of the Chinese fans by the Japanese media. Japan's China experts also categorized the violent behavior of the Chinese fans as a product of the nationalistic anti-Japanese education that young Chinese receive. Some like Professor Kojima Tomoyuki of Keio University harshly criticized China. “The anti-Japanese bias in their education has gone too far,” he wrote in The Asahi Shimbun of August 31, 2004. Television news and variety “Wideshow” Programs went as far as to assert that if China continues to drag politics into sports, it is not qualified to host the 2008 Olympics. An August 8 editorial of the Asahi Shimbun states, “[The actions of Chinese fans] at the final match between China and Japan gave us an opportunity to see the mindset of the Chinese who will be welcoming us at the Olympics in four years.”
