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 was organized by related landowners and the government, and discussions were held on how to develop the area, leading to increased momentum for redevelopment in the Marunouchi area. In this environment, the decision was made to rebuild the Maru Building and Shoji Building, marking the first time that assessment was applied in the area.
The Marunouchi Redevelopment Plan was groundbreaking in that it incorporated environmental impact considerations into its concept and presented and questioned the public, making it a pioneering attempt in strategic assessment. The Maru Building and Shoji Building as individual projects were also groundbreaking in terms of urban planning, as they were planned using a method of increasing the volume of land in specific blocks.
This assessment was the first of its kind in the Marunouchi area, which is undergoing renewal as a city that can be proud of around the world as the heart of Japan, and it is a significant project as it has been a pioneer in the numerous assessments that have followed in the area since, for example, it has utilized the spirit at the time of the announcement of the Marunouchi Redevelopment Plan to advance the project while promoting interaction with society based on information disclosure, and it has been planned with cutting-edge environmental considerations at the forefront.The following overview is for Marunouchi Building.
