The project area is located to the west of Roppongi-itchome Station on the Tokyo Metro Namboku Line. On the east side of the station, the Roppongi 1-chome Western Area redevelopment project—which encompassed Izumi Garden Tower and other developments and was completed in 2002—in which the Company participated, and other urban development projects had already been underway. However, on the west side of the station, there were no ticket gates and the traffic flow to the station was inconvenient. Additionally, the roads and sidewalks were narrow and there were problems with pedestrian safety. Furthermore, there was also a large difference in elevation within the project area, which failed to take advantage of being located in front of a train station, with both small and aging buildings standing adjacent to one another.

To solve these problems, the office building Sumitomo Fudosan Roppongi Grand Tower was built as the core of highly disaster-resilient buildings, and new ticket gates were constructed at the west exit of the station. Additionally, we developed a plaza in front of the subway station and a subway passageway connecting Roppongi-dori Street to the station, widened the surrounding roads, and created several plazas that serve as temporary evacuation areas in the event of a disaster. We divided the area into two zones, north and south, taking advantage of its topographical characteristics with elevation differences, while maintaining the continuity and harmony of the townscape with the Roppongi 1-chome Western Area. Through these efforts, we successfully performed urban development that added new aspects of convenience and disaster prevention that are befitting for a station-front location, with the district now housing various functions and serving various purposes such as business, commerce, and housing.

Development of a comfortable pedestrian traffic flow connecting the station and the area

As a base in front of the station on the west side, new ticket gates were built at the west exit of Roppongi-itchome Station to increase convenience for the local community. In addition, a subway passageway connecting Roppongi-dori Street to the station and an east-west free passage were constructed to strengthen the pedestrian network between the east and west sides of the station.
Along the subway passageway, there are an about 750-square-meter subway station square and an about 530-square-meter connecting plaza, as well as retail stores to create a new space that attracts many visitors. And, to make the building barrier-free, several elevators have been installed.
