Never been on a Japanese subway but I have been on a Chinese one. Pretty scary. I got packed into a Chinese train one time for an hour and half trip back to Shanghai. It was the middle of summer and it was about 90 degrees outside, warmer in the train. Fortunately, even if you were to pass out from the heat, you wouldn't fall down. You'd just stay packed in, like a cigarette in an unopened pack.

My wife was born and raised in China and the first time she came to the U.S. she was 27. We live in San Jose, CA, the 9th largest city in the country with over a million people. One of her first comments when she got here was was "where is everybody?"
