If you are claustrophobic, don't ride the trains in Japan.People with this fear of closed in spaces would not do well in this situation. This takes crowded train to a whole new level if you ask me.

During January I was in New York City and had to ride the subway at rush hour. I thought I was going to die. There were more people in one train car than there are people in Estherwood. This makes my face in the back of the person next to me ride look like a walk in the park.

The guys in uniforms are actually paid to help load the train. The literally push more and more people into the car until there is simply no more room. Maybe this is one of the reasons you don't see so many fat people in Japan. There is no room for them. The Japanese have an entirely different view point of subway behavior than Americans do.

I personally would rather walk or just have a bullet in my brain before I would get on a train that was this crowded.
