Totally worth every cent you pay for the green pass in order to ride this baby. Super quick, clean, punctual and safe. Make sure you get to the station with plenty of time to spare because it really does leave exactly on time. You can see quick snippets of Japan through the Shinkansen windows, even better when another train goes past and you realise just how quickly you're going in comparison. Definitely not your average train trip at home.
The only thing is that if you're on a longer trip, buy a warm meal/snacks from the station or convenience store beforehand. There wasn't much of a selection from the trolley on the train.
