...when you squish onto a train and every part of your body is touching against another human being...with the exclusion of your face if you are lucky...and then you get pushed off the train at a station you really don't want to get off at so other passengers can get off the train and then you jump quickly back on...not realising in your blind panic that this is the way the train works in peak hour...happy memories

I love Japan...can't wait to return.

so will the crowd be GREATLY reduced after say about 9, 10am?

You will be fine around 9.30 ish and certainly by 10 am. We try to start our Tokyo days around 9.30 usually and while the trains may still be busy ie not guaranteed a seat, they are not the horror crush of rush hour

I just got back from Japan today and I think the tokyo rush hour is exciting! The yamanote line is so packed but you never get stuck in a station that you don't want to be. I went through rush hour with my backpacing bag on my way in and out of japan and its just fine if you can get a seat when the big rush of people off to a station.
