It's a fun experience just being in the absolutely packed rush hour Tokyo trains. Although I don't have to worry about claustrophobia since I'm 6'3 tall and I'm able to look out above the heads of everybody else.
Yeah, I travel to Japan frequently (in fact, my next trip is next week!) and I'm also tall. I love Japan, and I love Tokyo's public transportation. However, one of the things I don't like are the jammed-packed rush hour trains in Tokyo. It could be very uncomfortable. I try my best to plan my itineraries in such a way where I could avoid that commute as much as possible.
Complaints aside, I love Tokyo's train and subway network! I can get around easily, with most places being no more than a 20-minute walk away from the nearest train/subway station, and many of the lines that connect central Tokyo to its neighbors have express routes that skip many stations along the way. Some lines even have special cars with reserved seats that cost extra. I sometimes take them whenever they are available; they make for a very comfortable ride.
