In the creation of cities, Mori Building always pursues three missions: “Safety and Security”, “Environment and Greenery”, and “Culture and Art”.
“Safety and Security” The creation of communities that people will seek refuge in, not run away from in times of disaster.
“Environment and Greenery” We believe that cities and nature can coexist.
“Culture and Art” We build cities that will give birth to new creativity and possibilities.
Adopting the “Vertical Garden Cities” as our redevelopment concept, one of our primary missions is to build environmentally friendly cities rich in greenery, striving to maximize open space and “green” the cityscape. Through intelligent consolidation and redevelopment of densely developed areas and the building of high-rise buildings to free surface land for greenery and by taking proactive steps to “green” the buildings with roof gardens, we are able to create numerous corners of nature within the city. This approach to city building not only contributes to the beautification of the environment but also mitigates the heat island phenomenon.
- ARK Hills Roof Garden
Since the early 1970's more than three decades ago, Mori Building has been strongly advocating the greening of our urban environment as evidenced by our slogan “Building Cities Rich in Greenery and Light.” We have been endeavoring to create cities in harmony with nature by freeing open space in central urban areas through redevelopment and taking proactive steps to “green” rooftops of buildings. Among our many achievements, ARK Hills, with its garden on the rooftop of Suntory Hall, was a pioneering step in the greening of urban rooftops, and provided a model for our efforts to create of greenery through redevelopment in subsequent projects.
- Model of the ideal "Vertical Garden City"
Our ideal is “Vertical Garden Cities”. This concept aims at creating microcosms of nature in the city, using the open areas freed by the consolidation and vertical redevelopment of small land parcels. It also promotes the restoration of natural beauty to neighboring and suburban areas. Our approach to the “greening” of the city is not simply a matter of planting more flora. Carefully selecting trees and flowers that evoke the seasons and planting fruit trees and grains that recall the joy of the harvest, we recreate a pastoral landscape that touches Japanese sensibilities and recalls memories of an earlier time. These corners of nature lighten and refresh the hearts of the people who live and gather there, and provide a place of safety and relaxation.
- Hills Gardening Club members lend Mother Nature a hand.
By serving as venues for the activities of gardening clubs formed by private citizen volunteers, the pockets of greenery that we have created also play a part in the formation of communities in the city where people-to-people connections have grown increasingly weak. Also through various events held, we provide an opportunity for children to have fun while learning about the importance of caring for our natural environment.
- Lower temperature of the Roppongi Hills area is clearly evident
"Vertical Garden Cities" are also effective in reducing CO2 emissions and energy consumption as well as contributing to resource conservation. It is a key to achieving a sustainable city that places a reduced burden on the environment. For example, the high durability and high earthquake resistance of structures contributes to resource conservation by minimizing damage from earthquakes and other disasters. The large open spaces and rooftop “greening” mitigate the heat island phenomenon. In addition, the consolidation of functions in the city enables preservation of nature and greenery in the suburban areas while the mixed-use urban model brings the workplace closer to the residence, reducing energy expenditure to move both people and goods. Moreover, Roppongi Hills boasts its own high-efficiency power generation system and is evolving into a city that is self-sustaining in terms of energy.
Mori Building actively undertakes the greening of the open space and rooftop area created by the redevelopment of areas with a high building density and the construction of high-rise buildings to replace them. This approach to the redevelopment and greening of urban areas is on the rise.

Since the ARK Hills redevelopment project, rainwater is collected by all buildings in all development areas is utilized after appropriate filtering and processing. Also in the case of large-scale redevelopment projects such as Roppongi Hills, wastewater (exclusive of sewage water and rainwater) is recycled.
Exploiting the merits of comprehensive development, Mori Building has been able to introduce District Heating/Cooling systems to promote efficient energy usage throughout the entire service area. Also to further reduce the burden on the natural environment, we are introducing thermal storage systems and BEMS (Building Energy Management Systems).
