AECOM, in conjunction with Skidmore, Owings and Merrill and Nikken Sekkei, served as master landscape architects to develop the former self-defense agency site in Roppongi, Tokyo.The 25-acre Tokyo Midtown Project is a world-class mixed-use complex that has become a landmark for the City of Tokyo, and the premiere address in Japan. The new development encompasses approximately six million square feet of office, residential, retail, and hotel space.The landscape design of the Tokyo Midtown Project marks a significant shift in Japanese development, as over 50 percent of the site's land is open or green space. The complex's diverse elements were designed to be in dialogue with the surrounding open-space and expansive greenery, creating a flow between the outdoor environment and the interior of the complex.One of the most notable features of the new landscape design is the more than 130 mature trees that were preserved and transplanted on the site to form a "greenbelt walkway." AECOM's design recalls the history of the site and the stream that once flowed across it, blending traditional Japanese influences with contemporary design elements in a series of gardens and fountains linked together by the braided walkway.The project opened on March 30, 2007, and was honored with the Urban Land Institute’s Global Award of Excellence in 2008.
