In the urban areas of Japan, the transportation networks are well established with railways that allow a means of commuting or going shopping by train, with less delay than driving a car. This situation is unique among the Asian countries.

The users of Tokyo Metro, which connects areas in the city of Tokyo, include various people such as business people, students and tourists.

Tokyo Metro is a closed environment of train interiors and train stations that are underground where the scenery is blocked. Therefore, advertisements tend to be seen easily and media contact rate is high.

Tokyo Metro operates 9 lines of subways and a total of 6.84 million people use Tokyo Metro every day. Because Tokyo Metro's network runs through central Tokyo with office districts such as Marunouchi and Kasumigaseki, shopping areas such as Ginza and Shinjuku, tourist districts such as Asakusa, Ueno and Roppongi, it is used by many people coming and going day and night for shopping and leisure, many traveling from the suburbs to central Tokyo.

Tokyo Metro utilizes the seamless central city network to provide a more precise and smooth transport service with the safety of the customers as its top priority.
