OK. I'll give you that one.
Tokyo always intimidated me, even though I grew up just south of NYC. I like the area around Hiroshima, especially Miyajima. Those dog-sized deer are just too irresistable. I spent so much on deer food I almost didn't have enough left for oyster donburi.
Comparison
Japan

Population : 127,463,611
US
Total Area : 9,826,630 sq km

In absolute figures US looks a long way from over populated...Density of population does not necessarily mean deterioration in life style ...
