From that link we sees Japanese military expense rise on to 5th in year 2003. Few years ago I read in my newspaper article that China military expense is actually less than the Japanese even.
I also read an article few days ago which written that Japan have become the country that have the highest military expense in Asia this year.
The Japanese every says that they need to become proper country by having troops and blablabla. But we see their military developement, we know that their military power have become more than a Defending troops should be.
Also, the Japanese military r actually more powerful than many other countries in Asia. No one in South East Asia can beat them, Korean cannot beat them. Even for China, it would have been a myst.
