Wrote about the Japanese "defence forces" for my masters dissertation...
Here's a few facts for you...
The Japanese are forbidden to have offensive armed forces in their constitution (which was written by the Americans after WW2)
Back in the mid nineties they had the second largest "defence" budget on the planet (after the US)
They had around 90 MPA (not sure what it is now, but more than us
)
They have had the most modern SSK fleet on the planet (they keep circa 16 SSK and build news ones all the time, retiring the "old" to keep the number stable)
With the American's they have the best theatre missile defence (TMD) going (both land-based and shipborne).
I could go on, but you should be pretty jealous by now. If not how about another fact...non-military this time.
They have zero immigration.
