The Mitsui Fudosan Group is committed to preserving and creating greenery, which will enrich and comfort people and serve as precious habitats for living organisms, in urban areas as much as possible, while at the same time restoring the habitats for living organisms that have been lost due to development works.

Efforts are made to restore and preserve the habitat environment for living organisms that have been lost due to development works. This is pursued in a way suited to the surrounding environment and property characteristics.

Initiatives at Shibaura Island

Shibaura Island is an area that was redeveloped by the Tokyo Metropolitan Government, Minato-ku and Urban Renaissance Agency, as well as Mitsui Fudosan and eight other private companies, joining hands with the public. The “preservation and restoration of the natural environment that was lost due to development works” was raised as one of the concepts of this development project and Mitsui Fudosan pursued this together with the Japanese Government, Tokyo Metropolitan Government and Minato-ku.
The revetment of Shibaura Island used to be a revetment made solely by solidifying soil and the habitat of many Chiromantes dehaani (a species of mudflat crab) and other living organisms. Part of the redevelopment project was to turn the revetment into a quake-proof revetment. If covered in concrete, living organisms cannot live. For that reason, a quake-proof revetment featuring crab revetment panels and tidal pool revetment designed for coexistence with living organisms developed by Kajima Corporation (known by the name “crab revetment”) was introduced in an effort to restore and preserve the habitat environment for the crabs and other living organisms. During the construction, the crabs living there were captured to be cared for by elementary school children in the area and then returned once the revetment was completed. As a result, many crabs have established their habitat there. Gobies, eels, freshwater prawns and other living organisms have also been found to be living in the tidal pool.

In order to maintain greenery as much as possible in urban areas where there is little greenery, efforts are made to increase greenery in ways that suit the characteristics of the region and properties.

Initiatives at Fine Court LaLaCity

Fine Court LaLaCity (Misato-shi, Saitama Prefecture) is a district of detached houses located in one section of SHIN MISATO LaLa-shi, which was developed on the former site of Musashino Yard. Urban development based on “improving with age” of growing exquisitely with the passage of time is pursued. Tall trees were planted at each house as a “house tree” that grows together with the family and home, and the intersections, etc. in the district were also lined with tall trees. In addition, various planting work was conducted along a road that stretches across the town named "Yukyu no Michi" (path of long history). In this manner, a landscape of sustainable lush greenery has been created.

Initiatives at Aoyama OM-SQUARE

Aoyama OM-SQUARE (Minato-ku, Tokyo) is situated near Meijijingu Gaien Garden where there is vast greenery. Consequently, harmony with the greenery of surrounding areas was raised as one concept of the development project. Based on this concept, greenery on the ground, roof and walls were created, centering on an open space on the northern side of the site. Three zelkova trees were planted at the center of the open space as symbolic trees, and a block of green space featuring a mixture of low, medium and tall trees, grass, flowers and other flora was created in the western periphery. In addition, low and medium trees were planted on the roof of the low-rise tower facing the open space. Furthermore, wall greenery was created at the entrance to the underground parking lot. In this manner, a variety of flora was planted in three dimensions.

In urban redevelopment, existing trees and woodland are preserved in an effort to ensure a place where precious living organisms can take habitat and a place people can take comfort in urban areas.

Initiatives at Park Court Jingumae

Park Court Jingumae (Shibuya-ku, Tokyo) is a for-sale condominium that emerged from a joint public-private development project aimed at revitalizing Jingumae 1-chome through the participation of private enterprises. The district used to be home to the family of Marquis Ikeda (former Tottori feudal lord) and the homestead woodland from those times still remained. This homestead woodland is the habitat environment for previous living organisms of the region, and is an important green space for connecting the forest of Meiji Jingu Shrine and the greenery of Togo Shrine that are dispersed in the area. Consequently, with the exception of part of the woodland that posed as a safety hazard or was no longer growing, most of the woodland was kept as preserved woodland. Rather than just retaining the woodland, a walking trail of about 140m long was also established and seasonal flowers and trees newly planted around it to create “Mori no Naka no Mori” (forest within a forest) that transforms from “greenery of the city” to "nature of the hills” and was opened to the public (closed at night) so that it can be enjoyed as a refreshing place by non-residents, too.
Overall, the development project for revitalizing Jingumae 1-chome through the participation of private enterprises has secured about 7,000m² of green space (includes about 1,000m² of rooftop greenery).
