http://www.ivebeenthere.co.uk/ Welcome to Been there. Your tips on the places you know - that you love, live in or have just visited - are what make this guide. http://www.ivebeenthere.co.uk/tips/2634
My advice would be to take no prisoners and try to manoeuvre yourself into a positon in front of the seats where the crush is not quite so intense, then take in the sheer lunacy of it all (meanwhile sparing a thought for those people who do this every day of their working lives). Discretely take a few photos so you can convey the experience to your friends. If you don't fancy getting up close and personal with dozens of "salarymen" inside the train, then you can always just observe from the platform.

One tip I have is to avoid travelling with bulky luggage during the rush-hour periods, especially the morning, for obvious reasons.]]> http://www.ivebeenthere.co.uk/tips/2634
