●Inside the station
When a train is delayed by 15 or more minutes or is suspended, a notice will be made on the Ticket Gate Display installed near the ticket gate of each station in English, Chinese (traditional Chinese, simplified Chinese) and Korean. When there is a temporary suspension of operation, we also make announcements in English in stations.
●Outside the station
If a train on any line of Tokyo Metro is or is expected to be delayed for 15 minutes or more, it is announced on the Tokyo Metro PC and mobile websites. (Japanese only)
