What's behind Japan's massive military build-up plan

Japan is arming itself like it never has before. The Defense Ministry has now asked for a nearly 12% budget increase this year, to finance the acquisition of warships and long range cruise missiles. If approved, it would be the second straight year of the new five-year military build-up plan that was approved in December last year. The request to increase the defense budget as part of that plan, came a day after Japan's top uniformed officer, General Yoshihide Yoshida warned that the neglected state of the country's Self-Defence Forces had put it's very sovereignty in jeopardy.
