Japan took action in emergency situations a record high 306 times in fiscal year 2012 (through March) in response to Chinese intrusions of its airspace, according to the Japan Times.
The scrambles against the Chinese surpassed those against Russia for the first time.
Scrambles by Air Self-Defense Force jets against Chinese aircraft rose due to heightened tensions over the Japanese-administered Senkaku Islands in the East China Sea following Tokyo’s effective nationalization last September of the islet chain. […]
The latest figure is almost double the previous record for scrambles against Chinese aircraft, at 156, and marks the highest level since the office began announcing figures by country in fiscal 2001.
The Japanese Defense Ministry’s Joint Staff said it will keep tabs on Chinese actions.
