The idea for Navit Co. was born out of its president's own experience of getting stuck in the labyrinth of a Tokyo subway station. The station map maker is now looking to expand its services nationwide, capitalizing on its data-gathering know-how.

The Tokyo-based company makes railway route maps as well as graphics of station and airport layouts. The subway car ride-spot guide posters were Navit's product that first grabbed the attention of many passengers.

The posters are designed to help train riders find the quickest way out of the station after they get off a train. They show the best car of the train to ride on to get off at the spot closest to the exit of each station.
