Business Details
Engages in the contracting of civil engineering works in Japan and related businesses. In addition to the parent company, consolidated subsidiaries Goei Doboku Co., Ltd. and Yosin Construction Co., Ltd. serve as key operators. Primary customers are government agencies (Ministry of Land, Infrastructure, Transport and Tourism, etc.), providing social infrastructure such as ports, revetments, tunnels, and roads. Steady public investment driven by disaster prevention/mitigation and national resilience measures underpins the business foundation, making this the reporting segment with the highest profit contribution to the overall group.
Recent Overview
Profit increased 44.8% year on year on steady progress of large-scale port works and improved margins
In FY2026 (ending March 2026), steady progress on backlog projects including large-scale port works expanded sales to external customers to ¥325,887 million (up 6.1% year on year). Improved project profitability from design changes and other factors also contributed, resulting in a substantial increase in segment profit to ¥40,200 million (up 44.8% year on year). Individual orders received approached a record high at ¥314,723 million (up 35.1% year on year), driven by strong government orders as well as contributions from large-scale private-sector projects. Year-end backlog also built up to ¥327,855 million (up 5.6% year on year), providing a solid sales foundation for the next fiscal year.
Key Products
Growth Drivers
- Continuation of steady public investment under disaster prevention/mitigation and the 5-Year Acceleration Plan for National Resilience
- Increase in large-scale government orders related to defense facility and infrastructure development amid strengthening of defense capabilities
- Expansion of orders for large-scale private-sector projects (logistics warehouses, data centers, etc.)
- Steady progress of backlog projects including large-scale works and improved project profitability through design changes, etc.
- Enhanced sales foundation for the next fiscal year from individual backlog of ¥327,855 million (up 5.6% year on year)
- Expansion on both fronts: domestic government orders of ¥225,453 million (up 31.2% year on year) and domestic private-sector orders of ¥89,269 million (up 46.1% year on year)
Risks
- Risk of rising construction costs due to persistently high construction material prices
- Risk of supply constraints and construction delays due to tight labor supply and worker shortages among partner companies
- Risk of order volume fluctuations due to government budget execution status and policy changes
- Impact on construction progress and profitability from changes in weather and marine conditions
- Risk of deteriorating profitability due to intensifying order competition
- Risk of surging crude oil and crude oil-derived material prices due to factors such as the situation in Iran
