Business Details
The construction business segment offers a diverse range of specialized civil engineering methods, including ground improvement work, pipe jacking work, diaphragm wall construction, underground obstacle removal, liquefaction countermeasure work, and slope reinforcement work. It operates in both the public and private sectors, targeting demand for various infrastructure renewal projects, including natural disaster prevention and recovery work. In Q1 of FY2027 (ending January 2027), net sales reached ¥2,267 million, accounting for 58.2% of total company sales, making it the largest segment and the primary driver of overall company profit.
Recent Overview
Both sales and profit increased substantially, but orders received declined 28.2% year-on-year, indicating weak order intake.
In Q1 cumulative of FY2027 (ending January 2027), net sales in the specialized civil engineering works business reached ¥2,267 million (up 24.5% year-on-year), and segment profit reached ¥276 million (up 89.5% year-on-year), achieving substantial growth in both sales and profit. This was due to steady progress in fulfilling the record-high order backlog from the end of the previous fiscal year. On the other hand, orders received in the current quarter were weak at ¥1,497 million (down 28.2% year-on-year), and the order backlog at quarter-end remained at ¥2,808 million (up 7.6% year-on-year), a decline from approximately ¥3,578 million at the end of the previous fiscal year. The share of total sales rose from 47.1% to 58.2%, leading the company-wide profit recovery.
Key Products
Growth Drivers
- Sustained expansion of public investment driven by national resilience policy and infrastructure aging countermeasures
- Continued demand for natural disaster prevention and recovery work
- Rising disaster prevention needs such as liquefaction countermeasures and ground improvement
- Diversification of revenue base through significant growth in private-sector sales (up 171.7% year-on-year)
- Improvement in segment profit margin through strengthened cost management and negotiation of settlement amounts at project completion
Risks
- Risk of future sales decline due to weak order intake (down 28.2% year-on-year)
- Constraints on construction capacity due to shortage and aging of skilled construction workers
- Cost increases from rising labor costs and construction material prices
- Tendency toward caution in private capital investment due to soaring construction prices
- Increased compliance costs related to overtime work hour caps
- Uncertainty in securing sales from Q2 onward due to decline in order backlog compared to the end of the previous fiscal year (from approximately ¥3,578 million to ¥2,808 million)
