Thanks to David Cenciotti for the heads up on this story.

Apparently in 2010 the ASDF launched 386 Quick Reaction Alert sorties against Chinese and Russian aircraft.

The Daily Yomiuri reports:

The number of Air Self-Defense Force sorties to intercept foreign aircraft flying near Japanese airspace jumped to 386 last fiscal year, up 29 percent from fiscal 2009, according to the Defense Ministry.
In the past two decades, the 2010 figure was the second-largest after the 488 sorties in fiscal 1991.

ASDF jets were scrambled to ward off planes from China 96 times, an increase of about 2.5 times from the previous fiscal year, and Russian aircraft on 264 occasions, an increase of 30 percent.

This probably explains a lot of the Russian Military Naval Aviation morse nets that get reported on UDXF so frequently.

An example of what can be heard on HF from the Ruskies:
