Environmental impact assessment for Marunouchi 2-2-1 and other blocks (Marunouchi Building / Mitsubishi Shoji Building)

Since Mitsubishi Estate announced the "Marunouchi Redevelopment Plan" in 1988, a redevelopment council composed of relevant landowners and governments has been organized to discuss the ideal way of urban development, and the momentum for redevelopment of the Marunouchi area has increased. Under these circumstances, the decision to rebuild the Marunou Building and the Shoji Building became the first assessment application in the area.
The Marunouchi Redevelopment Plan was groundbreaking in that it included environmental impact studies in the concept, and was a pioneering attempt at strategic assessment in that it was announced and questioned to the public. The Marunou Building and the Shoji Building as standalone businesses were also planned by a method of skipping the volume between city blocks by urban planning called a specific block, and it was groundbreaking as an urban plan.
This assessment is the first assessment in the Marunouchi area, which is being renewed as a city that can be proud of the world as the center of Japan, and as a pioneer in the assessment projects in the area that have continued one after another, such as the spirit of the "Marunouchi Redevelopment Plan" at the time of the announcement of the "Marunouchi Redevelopment Plan" and the promotion of the business while interacting with society based on information disclosure, and the fact that it was planned with the cutting-edge environmental considerations of the times at the forefront. The significance of this project is profound. The following summary is for Marunouchi Building.
