How to board the Shinkansen
You will receive two distinct tickets to board the Shinkansen: one is your basic fare ticket, and the other is a super express (Limited Express) ticket. If you have reserved a seat, your super express ticket will have your specific carriage and seat number printed on it.
Go to the Ticket Gates:
Once you have your physical tickets in hand, proceed through the automated ticket gate indicating a green arrow. Insert both the basic fare ticket and the super express ticket into the machine simultaneously, then remember to collect them from the other side.
Your platform number is clearly displayed on the large electronic departure boards. Locate the number and head straight up to the platform. Platforms for the Tokaido line, which takes you to Nagoya, Kyoto, and Tokyo, are usually 20 to 27.
Find your Carriage:
On the platform, look for the digital signs indicating exactly where each carriage will stop; you can also look for painted numbers on the platform floor that correspond to the carriage number printed on your ticket.
Boarding:
Once you are settled comfortably into your seat, the train conductor may walk through to inspect your ticket.
