That, and the annoying foot rest which takes up most of the space in front of you whether you need it or not were the only negatives. Awesome train (although the styling of the modern noses doesn't appeal to me at all) ride. Super smooth.
If you're going to be riding, don't dawdle getting off. You're expected to be at the door ready to get off when the train stops, if you wait, you'll be encountering passengers getting on, and the train doesn't stop long at the station.
p.s. Please don't get offended that I said Japan was a tick too small for me. It doesn't have to fit me, I don't live there. I was just making an observation. :)
