The newest flare up in a long-running territorial dispute between Asia's largest economies follows a similar incident on May 24, when Japan said Chinese aircraft had come within a few dozen metres of its warplanes.
"I would like the Chinese military authorities who allow this kind of dangerous behaviour to take place to behave morally."
China lays claim to Japanese-administered islets in the East China Sea, known as Senkaku in Japan and Diaoyu in China. It is also pressing its claim to almost all the South China Sea, brushing aside claims by several southeast Asian states.
Japan's Defence Ministry said the Chinese fighters came "abnormally close" to a Japanese OP-3C surveillance plane and a YS-11EB electronic intelligence aircraft between 11 a.m. and 12 a.m. (0200-0300 GMT).
The ministry's statement did not say how close the planes came to each other but added that neither the planes nor the Japanese pilots suffered damage or injury.
Japan scrambled fighter jets against Chinese planes 415 times in the year ended in March, up 36 percent on the year, while in waters near the disputed islands, patrol ships from both countries have been playing cat-and-mouse, raising fears of an accidental clash.
Japanese land, sea and air forces joined last month to simulate the recapture of a remote island, underscoring Tokyo's concerns about the security of the islets.
Tensions between China and its neighbours have also risen sharply in the South China Sea in recent weeks, following the deployment of a Chinese oil rig in waters also claimed by Vietnam. The deployment sparked anti-Chinese riots in Vietnam.Last Mod: 11 Haziran 2014, 13:50
