Building a company worth working at
Supply chain

We will continue working to create a safe and productive workplace built on the relationship of trust with our partner companies and other suppliers.

Haseko Group’s supply chain

The strength of Haseko Group’s condominium business lies in its unique business model based on exclusive contracts under which land is provided, as well as the Group’s collective capabilities in terms of identifying customers’ needs through sales, management, repair, etc., passing this information on in the form of feedback, and reflecting it effectively in business proposals, product planning, design and construction quality.

Development takes a long period of time, and involves diverse stakeholders. In particular, we have established a highly efficient and precise execution supervision system to pursue quality jointly with our business partners, i.e., cooperating companies with whom we build high-quality condominiums.


Haseko Value Enhancement Activities driven by framework of cooperation among "four bodies"

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 292 cooperating companies as of April 2020). 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, Inc.; "Tokyo Juyukai" and "Kansai Juyukai" at Haseko Reform, Inc.; and "Tokyo Kenshokai" and "Kansai Kenshokai" at Fuji Kensetsu Co., Ltd.


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.


Digital Utilization in Value Enhancement Activities

As part of our value enhancement activities, we are actively using ICT technologies in order to save labor and improve work efficiency.

Efforts are under way towards saving labor and improving work efficiency by employing a range of ICT technologies, such as adopting RFID tags in drainage testing and making effective use of apps for sharing digitalized drawings and construction photos.

Development of ball-passing test system using RFID (electronic tag) for drainpipes

Haseko Corporation developed a ball-passing test system utilizing RFID*1 for drainpipes, or “Drain Trace.”*2

A demonstration test was carried out in May 2018 for the purpose of increasing the efficiency of the ball-passing test for drainpipes*3, which had been conducted manually in facility inspections conducted before the completion of newly built for-sale condominiums. As a result, the inspection time and the time needed to prepare documents including inspection records were reduced.
The system is now in full-scale operation beginning with the facility inspection of newly built for-sale condominiums in the Tokyo metropolitan area and Kinki area that are scheduled to be handed over after April 2020, allowing us to gather evidence for the inspection results.

Going forward, we will also bring the system to the Chubu area and promote corporate-wide introduction of the system so as to enhance the efficiency of facility inspections and to help enhance productivity at construction workplaces.

*1 Radio Frequency Identification: an automatic recognition technology that enables non-contact reading and writing of electronic tag data through wireless communications
*2 Patent pending, trademark registered
*3 Ball-passing test for drainpipes that penetrate each unit. The test ball is put into the pipe from the rooftop air vent before running water, and is collected at the outdoor catch basin.

Promoting the introduction of “Construction Career Up System” to pass on the skills within 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 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. We will continue working to achieve 100% rates in company registration by March 2021 and in technician registration by March 2023.
