Tokyo Michi Terrace is a light-up event that has happened for the last few years on the Marunouchi side of Tokyo Station.
What happens?
Early versions featured projection mapping directly on to the newly restored facade of the station and the event was so popular that it was cancelled on one night due to the traffic disruption. Since then, it has been a lot tamer with more conventional illuminations and decorations along the promenade leading towards the Imperial Palace.
Organizers may cancel events, alter schedules, or change admission requirements without notice. Always check official sites before heading to an event.
