- Tokyo Mid-town Project (tentative name) -

Representative: Mitsui Fudosan Co., Ltd.
The consortium comprising of the National Mutual Insurance Federation of Agricultural Cooperatives, Meiji Yasuda Life Insurance Company, Sekisui House, Ltd., Fukoku Mutual Life Insurance Company, Daido Life Insurance Company and Mitsui Fudosan Co., Ltd. is proud to announce the construction commencement of "Tokyo Mid-town Project (tentative name)", the urban redevelopment project at the former Defense Agency site in Roppongi (Akasaka 9-chome Project). Takenaka Corporation and Taisei Corporation will head the construction with completion and grand opening expected in Spring 2007.
We are also pleased to announce that the Suntory Museum of Art, known for disseminating Japanese culture here and abroad will be relocated from Moto-Akasaka to be situated within our project site.
Recognized as an international center of Tokyo, Roppongi is home to a large number of embassies and foreign residents. This city which is lively around-the-clock all year round strikes a successful balance among work, life, entertainments and relaxation. With several large-scale developments currently under construction in the area, our project site has a great potential to become one of Tokyo's international gateways where new values would be created
Along with the adjacent Hinokicho Park which will be redeveloped as a vast open public space, the site provides 4 hectares of vast greenery in the heart of Tokyo. In prior to the commencement of construction, we transplanted to preserve approximately 140 existing trees including camphor trees, ginkgo trees, cherry trees and many others in order to "succeed the invaluable greenery".
Taking advantage of the greenery as a platform and under the slogan "Diversity on the Green", we are working to establish a community with a capacity to transmit new "Japanese Values" through the interactions among companies and people gathered from all parts of the globe. In order to create and achieve a fine urban landscape, U.S.-based firm, SOM (SKIDMORE, OWINGS & MERRILL LLP, Head Representative: Mr. David M. Childs) has been appointed as a master architect of the project for the development of a design guideline for the entire project. Subsequently, collaborations among several architects and designers, both domestic and foreign, have been realized to design respective sections of the site.
As previously announced, the world-renowned luxurious hotel chain "The Ritz-Carlton" will be situated at Tokyo Midtown. Aiming to become a new-age multipurpose compound, the project will not only integrate the separate functions of offices, hotel, residences and commercial facilities but also generate "something extra" by bringing about greater synergy among each function, placing a priority on the hotel as a principal function. For instance, enhanced values would be added through application of hotel hospitality/services to residences, and providing open green space as a business platform to workers at the Tokyo Midtown and so forth.. In this way, we are committed to a creation of a compound that produces new values through integration and interaction of functions.
Ever since its foundation in November 1961, the Suntory Museum of Art has "Art in Life" as its theme. Its fine line up of ancient & old Japanese arts/crafts, from painting, ceramics, lacquerware, dyed-fabrics, to glassworks has earned high reputation both home and abroad. The relocation of the Suntory Museum of Art (tentative name) is not a mere relocation but a realization of a "21st century type new-age museum". The museum plans expansion and we do not doubt that it will serve as cultural focal point and information center for this project.
Owing to the deep understanding and cooperation from the various relevant governmental agencies and local communities, city planning was decided in March last year and we are able to start construction works as a symbolic urban renaissance project only after two and half years of land purchase in September 2001 through open tendering. We are grateful and acknowledge the significance of the speedy progress of the project and pledge to continue to place all our efforts in creation and promotion of a safe and comfortable space that contributes to urban renaissance of Cosmopolis Tokyo.
