The Japanese air force started let flying its fighters after a Chinese intrusion into the japanese airspace. The Japanese media reported that the F-15 took off after a Chinese aircraft had been intercepted by the radar while flying over the Senkaku Islands, which Beijing calls instead Diaoyus, shortly after 11 am (local time). This would be the first violation of airspace reported from Tokyo to China. The government, said spokesman Osamu Fujimura, has mobilized the F-15 as soon as the Chinese air has been located.
The voltage was increased as early as four hours before departure of the air force, when four Chinese vessels patrol had entered the waters of the Senkaku / Diaoyu, a move seen at least 15 other times in the last three months. A Japanese Coast Guard has ordered them to leave the area, but in response, according to the Kyodo news agency, has been told by the vessels that the waters are Chinese “since immemorial time”.
The Japanese Foreign Ministry has lodged a formal protest with the Chinese ambassador in Tokyo. The new incident comes on the day when Beijing recalls the Nanking Massacre, in which thousands of Chinese were killed by the military of the neighboring country in 1937. It ‘s the first time in the dispute over the islands that is officially claimed ownership the corresponding airspace.

But Beijing reacted with fury, with observers saying the riots that erupted across China had at least tacit backing from the Communist Party government.
