Protecting the precious environment
Pollution prevention and consideration for the local environment

Upon the development of condominiums, we give consideration to environmental pollution, noise, vibration, etc. and proactively propose the development of green areas.

Response to Soil and Water Pollution

In the acquisition of land, the Haseko Group investigates the usage history and conducts soil surveys by specialists if there is any doubt about soil contamination.

When soil contamination is confirmed, appropriate measures are taken including removal or containment of pollutants in accordance with the Soil Contamination Countermeasures Act and other relevant laws and regulations.

Similarly, we are responding appropriately to water pollution when problems are identified.

Consideration for the Local Environment

When constructing new condominiums or renovating existing properties, the Haseko Group makes efforts to give consideration to the local environment such as using low-vibration and low-noise construction vehicles and machinery.

For example, at the construction work site of the “Shibaura 2-chome, Minato Ward New Construction Project (tentative name),” we have been conducting cleanup activities on the surrounding roads before daily morning meeting since the start of construction in November 2018 as part of consideration for the local environment. In addition, we have taken measures to minimize the impact on the surrounding area such as installing soundproof sheets on top of temporary enclosures and taking measures to prevent noise during pile head processing.

Consideration for Biodiversity

Haseko acquires ABINC Business Site Certification


The Association for Business Innovation in harmony with Nature and Community (ABINC) evaluates and certifies the biodiversity-conscious development, management, use, etc. of green areas in companies’ facilities (e.g., factories, office buildings, commercial facilities, condominiums) under its ABINC Business Site Certification (ABINC Certification), with the aim of promoting harmony between nature and people in corporate activities.

In fiscal 2020, two of the properties designed and constructed by Haseko obtained ABINC Certification. Amid the growing social interest in biodiversity consideration, we will contribute toward the improvement of the natural environment in cities by making proposals that take biodiversity into consideration.

Examples: Creating a Space with Greenery in Harmony with the Environment

PROUD CITY KICHIJOJI, Musashino City, Tokyo

PROUD CITY KICHIJOJI is located almost 2 km from the Kichijoji Station, as well as from the Mitaka Station, of the JR Chuo Line, a tranquil place away from the busyness around the stations.
There is Inokashira Park in the neighborhood north of the property, and a longer walk takes you to locations that still maintain the appearance of the old Musashino uplands, such as Jindaiji Temple and Nogawa Park. Within the site of PROUD CITY KICHIJOJI—in the front zone where there is the entrance of the property—stand two Himalayan cedar trees, which are approximately 25m tall with the spread 18m wide and serve as a symbol of the neighborhood. It is estimated that these trees are about 80 years old. To ensure that they stay healthy, we had their root systems investigated by an arborist and identified the spread of their roots. Then we developed a plan that considered not only securing an appropriate space in the front zone but also protecting these cedar trees.
In the site, meanwhile, there are several courtyards surrounded by residential buildings, where we put in place dense vegetation that extends to the greenery in the front zone. In this green space, there is also a wooden communal building, which gives residents a sense of the warmth of wood.
The zone where this property adjoins OUKAS KICHIJOJI —a residential building developed by Nomura Real Estate for the elderly provided with home-care services—is designed to serve as an integrated, garden-like pathway where the residents of the two properties can interact.


THE GARDENS OTA TAMAGAWA is a 12-minute walk from the Yaguchinowatashi Station of the Tokyu Tamagawa Line. The property is faced with the Tama River on its south side and located in a place where people can enjoy the comfort of river water and greenery grown along the riverside while living in the metropolitan area.
Within the site of THE GARDENS OTA TAMAGAWA, we have created green spaces that are connected with the rich natural environment of the neighborhood to produce two kinds of effects, “value added as a place to live” and “improvement of the local natural environment.”
The site is composed of three areas: “Approach Garden,” where a tunnel of greenery welcomes residents and guests; “Community Garden,” a green space created with artificial turf and scrub where people can enjoy activities; and “Central Garden,” a courtyard where residents can feel as if they lived in the woods.
We have planted trees that were selected based on the result of an ecological environment survey of the surrounding area, the kinds of trees that can have ecological connections with the vegetation in the neighborhood while also attracting living creatures in the area. We have also developed “Rain Garden,” which temporarily stores rainwater and lets it slowly spread into the ground. We have incorporated the image of the flow of the Tama River in the design of “Central Garden,” while also featuring environmental friendliness in this project.
We have acquired the ABINC certification for the site of THE GARDENS OTA TAMAGAWA.
