Reading the platform floor: car numbers, door marks, and where to stand in Japan

On most Japanese platforms, the floor tells you where to stand before the train pulls in. Numbered plates, painted door outlines and small colour codes do the work, and once you can read them, boarding stops being guesswork.

Numbers under your feet

Near the platform edge you will find markers reading 1号車 (ichi-gōsha, car 1), 2号車 and so on, with the door positions outlined beside them. The numbers match those printed on the train, and on limited express services they match the car number on your reserved-seat ticket.

Shapes and colours by train type

Where several kinds of train share a platform, each stops in a slightly different place. The markings are coded by colour or shape, a circle for one service and a triangle for another, with a key on a nearby pillar or overhead sign. Check the departure board for the train type, then find its symbol.

Picking a car for the exit

Route apps such as Navitime and Jorudan can show which car stops nearest the stairs or transfer at your destination, and some stations post a similar diagram on the platform. With a suitcase, a car near the lift saves more time than a faster connection.

Pink markings reading 女性専用車 (josei sen'yōsha) indicate women-only cars on certain lines, usually during weekday morning rush. The hours are printed on the sign.

How the queue works

At each door marker, people line up in two columns on either side, leaving the centre clear for passengers getting off. Joining the back of a line, not its side, is the whole rule.
