Business Details

Engages in precut processing, panel manufacturing, and sales of timber under the conventional (wooden post-and-beam) method and the two-by-four method. Has established an integrated system from lumber processing to delivery and erection work. Primary customers are homebuilders and construction firms, with the value proposition centered on quality stability, shortened construction periods, and cost reduction through machine processing. This core business accounts for approximately 65% of consolidated net sales in FY2026 (ending May 2026). Note that from the current period, CSL CAD VIETNAM COMPANY LIMITED was excluded from the scope of consolidation.

Recent Overview

Segment profit plunged 92.5% year on year amid the housing starts slump and intensifying price competition

In FY2026 (ending May 2026), the Precut Business saw new housing starts decline 5.3% amid a reactionary drop following the pre-revision rush ahead of the amended Building Standards Act enforcement and prolonged building confirmation procedures; profitability deteriorated sharply due to intensified price competition with industry peers. Net sales came to ¥14,430 million (down 5.4% year on year), and segment profit fell sharply to ¥55 million (down 92.5%). In February 2026, the company integrated the Conventional Method and 2x4 Sales Headquarters into a new sales headquarters and accelerated efforts to win orders for large-scale non-residential projects and to promote the integrated materials-and-labor initiative, but this did not lead to a recovery in performance.

service
Integrated Materials-and-Labor Service (Including Erection Work)

Accelerating the "integrated materials-and-labor" initiative that combines material supply with erection work and other services. Promoted as a measure to secure sales amid the slump in housing starts, this is also a value-added service that contributes to improving customer productivity.

product
Siding (Exterior Wall Material) Precut

Under the newly established sales headquarters formed in February 2026 by integrating the Conventional Method Sales Headquarters and the 2x4 Sales Headquarters, the company is actively pursuing customer development for the siding precut business. Sales activities are underway that are expected to lead to orders from the next period onward.

Growth Drivers

  • Enhancing added value and securing stable orders through integrated materials-and-labor provision (combined with erection work, etc.)
  • Diversifying revenue sources by promoting customer development in the siding (exterior wall material) precut business
  • Expanding orders for large-scale non-residential properties (wooden welfare facilities, nursery facilities, etc.)
  • Strengthening overall sales capability through the integration of the Conventional Method and 2x4 Sales Headquarters
  • Pursuing yield improvement and delivery efficiency by leveraging in-house lumber processing and delivery

Risks

  • The medium- to long-term downward trend in new housing starts (down 5.3% year on year on a cumulative basis for FY2026, ending May 2026)
  • Unit price declines and margin pressure from intensifying order competition with industry peers
  • Rising housing construction costs and weakening homebuyer sentiment due to soaring building materials and labor costs
  • Further cooling of housing demand due to concerns over rising mortgage rates following the Bank of Japan's policy rate hikes
  • Price increases and supply constraints for petroleum-derived building materials (paints, insulation, adhesives, etc.) amid heightened tensions in the Middle East, and resulting construction delays at job sites
  • Labor shortage risk stemming from the aging of the carpenter workforce
