I will personally vouch for Shinjuku being the busiest train station. After several years of being pushed by old ladies, packed like a sardine by door attendants I couldn't disagree.

I think I did see the story about the dead man's remains on the BBC website a few months ago. I thought it was one of most fascinating articles I read recently.

I've just been here for two weeks and everyday I used the shinjuku station to get to Hatagaya and everywhere I look there's people and when I went out for a walk or to eat there's the same kind of scene daily. I wonder if the people in Shinjuku really sleeps at all??
