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 contamination (brownfield redevelopment)

In the acquisition of land, the Haseko Group investigates the usage history and conducts soil surveys by third-party specialists if there is any doubt about soil contamination.
When soil contamination is confirmed, based on the survey results, we consider costs, scheduling, and procedures, which include the cancellation of designations of areas that require measures and of designations of areas that require notification for any intended change in characteristic s in accordance with the Soil Contamination Countermeasures Act and other relevant laws and regulations. We then choose the most appropriate method for dealing with the contamination backed by our abundant experience. We take measures to prevent the spread of contamination, including excavation and removal or containment of pollutants.
Some of the contaminated soil which is excavated and removed is transported to cement works and other facilities conforming to relevant laws and regulations, and recycled as raw materials.
General waste soil resulting from excavation work at construction sites is disposed appropriately in accordance with relevant laws and regulations.

Construction site effluent quality management

For each construction site, Haseko Corporation establishes effluent plans after confirming relevant laws and regulations for the area.
It thoroughly manages the quality of construction site effluent using the Company’s own environmental law and regulation check sheet.
Management status is confirmed via an environmental patrol by a specialist division, and no issues have arisen to date.

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.

At some construction work sites, we have taken measures to minimize the impact on the surrounding area such as intermittently cleaning up the surrounding area, installing soundproof sheets on top of temporary enclosures, and taking measures to prevent noise during pile head processing.

Consideration for Biodiversity

Haseko Corporation obtains a Japanese OECM Site Certification by the Ministry of the Environment


Haseko Corporation applied for and obtained the Ministry of the Environment certification of Haseko Technical Center as a Japanese OECM (other effective area-based conservation measures) site (as of October 6, 2023).
30by30 is a global biodiversity initiative aimed at effectively conserving healthy ecosystems of at least 30% of land and sea areas by 2030. Haseko Corporation has participated in an OECM site initiatives, which contribute to 30by30 targets in Japan, from the trial project in fiscal 2022, and the Company has now officially acquired the certification.
Through this certification, the Haseko Group plans to contribute at an even higher level to maintaining the value of and improving the quality of biodiversity, and to achieving Japan’s 30by30 targets.

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 2022, one 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.

Renai Tomio, Nara City, Nara

Renai Tomio is located a 5-minute walk from “Tomio Station” on the Kintetsu Nara Line, with high convenience, and nature can be felt close by.
New greenery has been created around the station, connecting the foliage of the Yata hills. The attractively designed “Promenade Garden” at the center of the site serves as a hallmark of the condominium complex. We strive to attract plenty of living creatures and create a future with a rich environment. In the “Forest of Symbiosis”, Kasumi cherry trees and Japanese snowbell trees found in the region’s hillsides are symbolically planted. Konara oak, Koba-no-gamazumi, Japanese photinia, Kojii, Nanami-no-ki trees and other native plants, a common sight in the Yata hills located on the west side of the property, are planted, creating green space that is in harmony with the natural surroundings. We are actively working to attract living creatures by selecting the great tits, Japanese white-eyes, oriental greenfinches and Japanese pygmy woodpeckers among birds found on the surrounding greenery areas, planting Japanese maples, red bayberry and Nanami-no-ki trees, which such birds like as food, throughout the site, and placing birdhouses and birdbaths.

Garden Cross Tokyo Oji, Kita-ku, Tokyo

“Garden Cross Tokyo Oji” is a ten-minute walk from the Oji Station on the JR Keihin-Tohoku Line in Tokyo’s Kita-ku, located within “the Next Generation Residential and Industrial Complex Zone” that is part of Kita-ku’s town development grand design. In light of its location, we made a plan that is open to the community, by building disaster prevention squares and walkways, and facilities that contribute to the community as a venue that connects residence and industry.
The condominium incorporated the historical background of the development of the Shakujii and the Sumida River water transportation system, and it was designed to look like a luxury cruise. In line with this theme, public space and the courtyard as the landscape are designed to resemble the deck of a ship, and benches and a stage square are placed against a backdrop of thick green shade, thereby creating a pleasant deck where one can enjoy the green shade of the four seasons in harmony with common facilities.
The site consists of four spaces: the “Grand Entrance Sakura Plaza”, an open terrace with “cherry blossoms” reminiscent of the Asukayama Park; “Central Garden”, a terrace where you can relax in a safe space within security; “Garden paths” with paths that mimic the flow of water and shaded green areas; and “Gate Entrance”, a shaded green gate with easy access from the station. These four spaces are designed to take pedestrians on a journey through rich greenery.
This site obtained ABINC Business Site Certification. Its aim was to restore local greenery by introducing potential natural vegetation and substitutional vegetation to the area, which was lacking in greenery, and create a town where residents could live in harmony with creatures living in the urban area. Community-building events are also organized as a part of the monitoring process. We are making use of a nature learning space to create an environment that connects people with each other.

This reduces the amount of atmospheric CO2 and helps to prevent global warming.
