Mori Building recently announced that it plans an extensive redevelopment of the area around the existing Toranomon Hills building which will involve the development of three new mixed-use towers tentatively called Toranomon Hills Business Tower, Toranomon Hills Residential Tower and Toranomon Hills Station Tower. Already under construction is a new station for the Hibiya subway line being developed by Urban Renaissance Agency.
At 52-stories, Toranomon Hills is one of Tokyo’s premiere mixed-use complexes and the second tallest building in Japan by building height (247 meters, 810 feet) and was built in 2014. The top six floors are occupied by the Andaz Tokyo Toranomon Hills, a luxury boutique lifestyle hotel with a spa on the 37th floor.
Vertical Garden Cities Integrated with New Stations
Mori envisions this project as a harmonious complex that will be smoothly integrated with all transportation options, transforming Toranomon into a gateway to Tokyo and a hub for international business.
When completed, the Toranomon Hills complex will reach about 7.5 hectares in floor size, including the four Toranomon Hills towers, new transport stations, roads and green space.
There will be about 800,000-square meters of total floor space, approximately equivalent to that of Roppongi Hills, including about 300,000-square meters of office space and 26,000-square meters of retail space.
The site will also house a new subway station on the Hibiya Line and a new Bus Rapid Transit (BRT) station that will connect central Tokyo and the bay area. As such, it will play a key role in shuttling athletes and tourists back and forth between central Tokyo and many of the 2020 Olympic venues planned for Tokyo Bay.
Toranomon Hills Business Tower
This building will generate some 94,000-square meters of office space by 2019. The 36-floor tower will house the Innovation Center, offering office space, salons and seminar venues for venture capitalists and top companies’ new business development divisions.
New Airport Connections
The tower will house the new BRT station connecting central Tokyo, the bay area and various venues for Tokyo 2020 Olympic and Paralympic Games, as well as a new Airport Limousine bus terminal that will connect Toranomon to Tokyo’s international airports. BRT will be able to carry some 3,000 people per hour and is expected to serve as an important mode of transportation during the Games, carrying international athletes and audiences alike.
Toranomon Hills Residential Tower
This building will supply 600 premium residential units by 2019, bringing the total number in the Toranomon Hills complex to about 800. Responding to the needs of long-term foreign visitors, the 56-floor tower will offer large-scale residential units and serviced apartments with Western-style en-suite bathrooms, a spa and fitness center, childcare facilities and a 24-hour bilingual concierge on site.
Toranomon Hills Station Tower
This will be a unique redevelopment collaboration combining a multi-use high-rise constructed by Mori with a new subway station created by Urban Renaissance Agency.
Moving forward, Mori Building will undertake a total of ten large-scale redevelopment projects in Toranomon and surrounding areas, with these three towers at the nexus.
Impact on Toranomon Already Felt
Mori’s redevelopment projects in Toranomon have already brought tangible results to the area, an impact which is expected to accelerate with these new projects.
Since the inauguration of existing Toranomon Hills, land prices have jumped by about 34.4 percent and the number of people using Toranomon Station has increased by 7 percent.
At Toranomon Hills complex alone, the large-scale office space to be created in this development is expected to triple the number of people working in the complex to 30,000. Meanwhile, projects by Mori and other developers in the larger Toranomon area are forecast to add more new office space over the next 10 years than was added over the last 30 years.
