Business Details

Handles paving, civil engineering, and construction work in general. Provides asphalt paving, concrete paving, civil engineering works and other services to expressway operating companies, the Ministry of Land, Infrastructure, Transport and Tourism and other public-sector clients, as well as private-sector customers. The company is promoting sales activities in the fields of aging infrastructure countermeasures and disaster prevention/mitigation, while also working to improve productivity and operational efficiency through the use of ICT technologies. It is focusing on strengthening its response capability for publicly ordered projects and on sales activities to expand its private-sector customer base.

Recent Overview

Both completed construction revenue and profit declined due to the reaction from the concentration of large-scale projects in the prior period, while contracts carried forward increased

Completed construction revenue for FY2026 (ending March 2026) was ¥74,658 million (down 7.1% year on year), and segment profit was ¥7,252 million (down 10.1% year on year). This reflects a decline compared with the prior period, in which large-scale projects were concentrated in construction. On the other hand, orders received of ¥75,765 million were roughly in line with the prior year, and contracts carried forward to the next period increased to ¥41,012 million (up ¥1,107 million year on year), maintaining the sales base for the next period. Notably, orders received for concrete paving expanded to approximately double the prior-period level.

Key Products

service
Asphalt paving works

The mainstay work type, accounting for the majority of construction business sales. Completed construction revenue for the period was ¥53,746 million (down 10.1% year on year). Renewal projects by expressway operators and repair/renewal works associated with national resilience measures are the main sources of demand. Orders received totaled ¥54,327 million.

service
Civil engineering works, etc.

Completed construction revenue for the period was ¥19,264 million (up 1.4% year on year), with orders received of ¥18,540 million (up 11.8% year on year). This accounts for 20.2% of completed construction revenue, the second-largest work type after asphalt paving. Orders are mainly from the Ministry of Land, Infrastructure, Transport and Tourism and local governments.

service
Concrete paving works

Completed construction revenue for the period was ¥1,647 million (up 6.0% year on year), and orders received increased substantially to ¥2,897 million (up 95.7% year on year). Contracts carried forward also increased by ¥1,250 million year on year to ¥1,783 million, suggesting a contribution to sales in future periods.

Growth Drivers

  • Continued orders for renewal projects (specified renewal works, etc.) placed by expressway operating companies
  • Steady trend in public investment supported by the government's promotion of national resilience measures
  • Expanding demand in the fields of aging infrastructure countermeasures and disaster prevention/mitigation (response to intensifying weather disasters and large-scale earthquakes)
  • Support for next-period sales from the accumulation of contracts carried forward, which reached ¥41,012 million
  • Sales activities aimed at strengthening the response system for publicly ordered projects and expanding the private-sector customer base
  • Improved on-site productivity and operational efficiency through the use of ICT technologies

Risks

  • Risk of rising construction costs due to persistently high raw material and energy prices
  • Risk of timing gaps in completed construction revenue and profit depending on the progress of large-scale projects
  • Impact on future sales from the declining trend in asphalt paving orders received (¥54,327 million for the period, down 6.2% year on year)
  • Chronic labor shortage risk due to the aging of technicians and declining entry of younger workers
  • Uncertainty in the business environment and elevated crude oil prices stemming from geopolitical risks such as the situation in the Middle East
  • Risk of rising labor costs in the construction industry
