Business Details

A segment mainly comprising Concrete Piles & Poles, Environmental Products (Concrete Blocks), Gravel Products, Wave-Dissipating Block Formwork Rental, and Technology Licensing Income. As a manufacturer providing foundation support capacity for structures, the company supplies high-quality concrete products together with construction and construction management technology. In the Pile division, revenue is recognized (using the input method) by treating product sales and contract construction work as a single performance obligation, with revenue recognized over a period of time accounting for the majority of sales. In FY2026 (ending March 2026), this core business accounted for approximately 83% of consolidated net sales.

Recent Overview

Amid declining demand and intensifying competition, orders for large-scale projects and enhanced sales efforts drove a 21.7% increase in net sales and a 39.7% increase in operating income.

In FY2026 (ending March 2026), the overall concrete pile industry's shipment volume declined 0.2% year on year (with private-sector demand increasing but public-sector demand decreasing), maintaining a challenging environment. The company worked to strengthen sales and improve construction efficiency, and secured orders for large-scale projects, resulting in an increase in sales volume. Net sales reached ¥83,159 million (up 21.7% year on year), and operating income reached ¥14,733 million (up 39.7% year on year), achieving substantial growth in both revenue and profit. Capital expenditures also increased 22.5% year on year to ¥4,998 million, continuing efforts to strengthen production and construction capacity.

Growth Drivers

  • Increase in private-sector construction demand (private-sector demand increased in FY2026, ending March 2026)
  • Expansion of sales volume through orders for large-scale projects
  • Strengthened competitiveness through enhanced sales efforts and improved construction efficiency
  • Strengthening of production and construction capacity through expanded capital expenditures (capital expenditures of ¥4,998 million)
  • Expectations for a recovery in industry demand toward FY2027 (ending March 2027)

Risks

  • Decline in public-sector demand (public-sector demand declined in FY2026, ending March 2026, with industry shipment volume down 0.2% year on year)
  • Risk of deteriorating profitability due to intensifying price competition with competitors (expected to continue into FY2027, ending March 2027)
  • Risk of rising costs due to elevated raw material prices remaining at high levels
  • Risk of construction losses arising from cost overruns relative to estimated construction costs (possible recognition of provision for construction losses)
  • Risk of fluctuations in revenue recognition due to design changes, schedule revisions, or construction delays
  • Risk of deteriorating performance, with the consolidated earnings forecast for FY2027 (ending March 2027) projecting a 7.9% decrease in net sales and a 19.3% decrease in operating income
