Basic Approach & Policy

Haseko Group Sustainable Procurement Guidelines

The Haseko Group’s business activities are possible due to the support of our many partner companies and other business partners. We consider our business partners to be valuable partners in promoting sustainability.
The Haseko Group promotes procurement activities in accordance with the Haseko Group Sustainable Procurement Guidelines (hereinafter, “the Guidelines”) with the purpose of building a sustainable supply chain. The Guidelines establish basic matters in conducting procurement activities that are conscious of the environment and society. We ask all of our business partners, including subcontractors and agents, to adhere to the Guidelines when conducting business activities.

Initiatives

Implementation of the Sustainable Procurement Guidelines

To ensure the effective implementation of the Haseko Group Sustainable Procurement Guidelines, we obtain written consent on the Guidelines from the partner company organizations of our Group companies, which are our main business partners. In addition, to ensure that all business partners clearly understand the requirement to comply with these guidelines, we are working to include compliance clauses in contracts and to obtain written consent from them.
Furthermore, by conducting a questionnaire of our business partners since FY2022, we are working to confirm adherence to the Guidelines and promote understanding and permeation of our initiatives.

Overview of the questionnaire

Below is an overview of the business partner questionnaire conducted in FY2025.

In July and August 2023, we conducted a questionnaire on the traceability of timber and a questionnaire on the treatment of foreign technical intern trainees employed by partner companies. Please refer to “Respect for Human Rights” for details.

Activities through partner companies’ organizations

Framework of cooperation among "four bodies"

Haseko Corporation is in charge of building condominiums with a high degree of precision through the combined efforts of the four bodies (i.e., the construction divisions, design divisions, and technological promotion divisions of Haseko Corporation as well as Ken-ei-kai, an organization of business partners consisting of approximately 300 major partner companies). This cooperative relationship has continued for more than 25 years, and our quality control framework built on strong ties is a strength that no other company has.
Our activities in pursuit of growth are conducted together with organizations of business partners, namely: Koshokai and Koshokai Kansai at Haseko Community; Tokyo Juyukai and Kansai Juyukai at Haseko Reform; Tokyo Kenshokai and Kansai Kenshokai at Fuji Kensetsu; and Shinwakai at Hosoda Corporation.

HASEKO Value Enhancement Activities

Value enhancement activities are activities to provide high-quality condominiums with the aim of clarifying the responsible construction scope, saving labor, and improving work efficiency and improving the Haseko brand based on cooperation between the technology-related divisions and Ken-ei-kai. Activities that are currently being promoted include initiatives to improve operational efficiency through the utilization of cutting-edge technologies as well as initiatives to further boost productivity aimed at instilling activities toward Workstyle Reform, which may be regarded as an industry-wide challenge. The outcome of activities are shared at the Debriefing Session on Value Enhancement Activities held once a year, in pursuit of succession, widespread acceptance, and collaboration at a deeper level.
In FY2020, we prepared a video in celebration of the 30th anniversary of our Haseko Value Enhancement initiatives to look back on the history of the efforts and provide an overview of future prospects including DX.
In and after fiscal 2021, we have made further progress on digitizing analog data at construction sites and promoted activities for shifting the process itself to digital. In addition, we newly established the BCP Subcommittee to address matters such as natural disasters while the existing CSR Subcommittee actively promotes initiatives such as environmental conservation, SDGs, and decarbonization.

Engagement with foreign workers from partner companies Global Workers Meeting

The number of foreign workers from partner companies working at construction sites of the Haseko Group is increasing year by year. Based on this situation, HASEKO Corporation holds Global Workers Meetings with an aim to establish engagement with foreign workers and to create a working environment easy for foreign workers to work in.
HASEKO Corporation employees participate in these meetings and identify the work-related and other problems of foreign workers working on Haseko sites and work to resolve and improve them. The Meetings are also used as opportunities to improve skills through various kinds of information provided by HASEKO Corporation and to deepen solidarity in the workplace through interaction between foreign workers.

The atmosphere of the Global Workers Meeting

Hosting opinion exchange dialogues of female technicians

Haseko Corporation is holding opinion exchange dialogues between female technicians from work places and the staff (members of the Value Enhancement Committee and the Workstyle Reform Subcommittee) on a regular basis.
The dialogue, under the theme of “honest opinions about worksites from women’s point of view,” is held in a roundtable-style to exchange views in a positive manner and invite requests regarding worksite facilities and equipment and worries and difficulties specific to women, among others. Based on the valuable views presented at each dialogue, we hold consultations with relevant divisions, implement improvements, and apply it to other sections, and work towards the betterment of the work environment.

Promoting the Construction Career Up System to pass on the skills in the construction industry

The Construction Career Up System is a private-public scheme developed by the Ministry of Land, Infrastructure, Transport and Tourism, the Japan Federation of Construction Contractors, the Associated General Contractors of Japan, the Federation of Specialized Construction Contractors, and the National Federation of Construction Workers’ Union, among others. Haseko Corporation regards this system as an epoch-making infrastructure that improves the treatment of on-site technicians and allows them to envision future career paths, and is therefore actively promoting its introduction.
The system issues each technician a chip card (Construction Career Up Card) on which his/her employment history and other information can be stored following an industry-wide uniform rule, with the aim of creating a mechanism in which technicians are evaluated in a fair and appropriate manner.
Haseko Corporation introduced the system in April 2019 and has achieved a 100% registration rate among our work sites in August of the same year. In FY2025, we achieved nearly all items of the targeted goal set by the Japan Federation of Construction Contractors. We will continue working to achieve 100% rates in both company and technician registrations within FY2026.
