Japan has the fifth highest military spending in the world. That's a lot of money. Further, military spending for the majority of the world is related to the real threat that they endure. What threats did Japan face? There was no chance of a Chinese invasion, and among the rest of the Asia Pacific countries things are relatively civil. The powder keg of India/Pakistan has nothing to do with Japan. As a second further, when you start dumping money into the military you generally just create a problem as everyone around you will start doing the same.
