The train number and destination are always shown in Japanese and in Latin characters. On many platforms,
floor markings show where the train doors are located. The trains stop exactly at the door markings.It is a good idea to queue to access the door as the trains do not stop for long. Additionally, seats are not booked in advance on local trains and the sooner you board, the better your chances of getting a seat.
Don't hesitate to ask a traveller on the platform if the train you are waiting for is going to your destination. Finally, be careful
not to take a 'Nozomi' train on the Tokyo-Nagoya-Kyoto-Hiroshima line. You must board the 'Hikari' or 'Kodama' which make a few extra stops.
