Reconstruction Plan for Shin-Marunouchi Building
~Marunouchi Redevelopment Continues-
Transition from Stage One to Stage Two~

Acting in response to the increasingly diversified demands of the growing global business environment in Tokyo, in June of last year, Mitsubishi Estate Co., Ltd. (MEC) announced plans to reconstruct the Shin-Marunouchi Building. Since that time, extensive discussions have been held with the Tokyo Metropolitan Government and Chiyoda Ward among others, and we are pleased to announce that an agreement has been reached regarding planning details.

In April 1998, MEC announced its plan to revitalize the Marunouchi District including the reconstruction of six (6) buildings in the area. The opening of the reconstructed Marunouchi Building in September of last year marked the first step toward culmination of the project. This was followed by completion of the Industry Club of Japan / Mitsubishi Trust And Banking Building. Current activities include the Marunouchi 1-chome, 1Area (tentative name, located in front of the Marunouchi north exit of Tokyo Station) Development Plan, and reconstruction plans for the Tokyo Building, Hibiya Park Building and Shin- Marunouchi Building. The complete renovation of these six sites by fiscal 2007 will mark the completion of “Stage One” of the Marunouchi District reconstruction.

As an extension of the abovementioned activities, based on the theme “A City of Global Interaction”, reconstruction of Marunouchi Naka Dori (Central Avenue) is underway. This corridor, connecting Marunouchi and Yurakucho, is being transformed into a place where people and information converge through the process of attracting commercial establishments and introducing new environments in which to create and promote business.

To bring “Stage Two” of Marunouchi reconstruction to fruition within the next 10 years, MEC will continue to promote revitalization throughout the area. It is our wish to make a positive, lasting contribution to a rejuvenated Marunouchi that captivates and inspires all while elevating Tokyo’s competitive standing on the international stage.
