Social System-Related Business

Based on our engineering capabilities cultivated through the development of telecommunications infrastructure, we are working on the “three pillars” of infrastructure, electricity and telecommunications, and renewable energy to prevent and mitigate natural disasters, improve the DX, safety, and convenience of society, and achieve carbon neutrality.

Infrastructure

We perform construction for the transition to pole-free infrastructure, water and sewage and river improvement and undertake civil engineering projects such as paving and gas conduit construction. We are also moving forward with data center interconnection (DCI), demand for which is growing.

Electric and Telecommunications Facilities

We take on the construction of electricity, air-conditioning and sanitation parts of buildings and also engage in projects for data centers, airports, hospitals and other facilities. Furthermore, we undertake the construction of road lighting, telecommunications equipment and power companies’ power distribution equipment.

Renewable Energy

To achieve carbon neutrality by 2050, we propose and construct GX solutions, such as large-scale solar power generation, residential solar power generation, and grid storage plants in growing demand.

The COMSYS Group's advantages

Advantage 1

Being a group of one-stop, comprehensive engineering companies that operate nationwide

The COMSYS Group is active in a broad range of domains including civil engineering, telecommunications, electricity, air-conditioning, sanitation, renewable energy and domains that are a necessary part of social infrastructure development. One advantage it has is the cooperation between Nippon COMSYS Corporation which operates nationwide and the locally rooted COMSYS Group companies.

Advantage 2

Technical strengths accumulated over the long term and established construction track record

The companies of the COMSYS Group have accumulated high-level technological and construction management capabilities over their many years performing telecommunications, civil engineering and electrical construction for telecommunications carriers. Leveraging this track record, they also undertake projects from government offices and private construction projects and have earned a high degree of trust from customers.

Contributing to the realization of a sustainable society

Contributing to the increased safety and convenience of expressways

9 INDUSTRY, INNOVATION AND INFRASTRUCTURE
11 SUSTAINABLE CITIES AND COMMUNITIES
15 LIFE ON LAND

The COMSYS Group contributes to the increased safety and convenience of expressways through communications construction for NEXCO companies, Metropolitan Expressway Company, Nagoya Expressway and others (e.g., surveillance cameras, electronic toll collection systems, road message signs) and electrical construction (e.g. lighting equipment, substation equipment).
We are also involved in the construction of free flow ETCs (roadside wireless devices) for the promotion of ITS (intelligent transport systems), and contribute to the elimination of traffic congestion and the optimization of discount toll rates through wireless communication between roadside wireless devices and on-board devices.
