Consolidated subsidiaries Kurimoto Shoji Co., Ltd., Yamatogawa Co., Ltd., and Hokkaido Kanzai Co., Ltd. serve as authorized distributors handling sales, while Kurimoto Pipe Engineering Co., Ltd. handles water pipeline design, construction, and management. This is the core segment, accounting for approximately 52% of consolidated net sales.
Recent Overview
Solid pipe shipments offset the drop-off effect in valves, resulting in a ¥3,754 million increase in net sales and a ¥703 million increase in profit year on year
In the Lifeline Business for FY2026 (ending March 2026), although net sales in the Valve Systems Division decreased due to the drop-off effect from large-scale projects recorded in the same period of the prior year, solid shipments of ductile iron pipes for waterworks in the Pipe Systems Division led to net sales to outside customers of ¥65,960 million, an increase of ¥3,754 million year on year. Segment profit increased by ¥703 million year on year to ¥4,732 million, driven by higher profit from increased sales. Capital investment aimed at reducing CO2 emissions and rationalizing ductile iron pipe production at the Kagaya Plant is underway, and the increase in tangible fixed assets, etc. reached ¥4,946 million, a substantial increase year on year.
Key Products
Growth Drivers
- Continued expansion of demand for renewal and seismic resilience upgrades of aging waterworks infrastructure
- Expanded response to lifeline renewal projects in the agricultural water, sewerage, defense, and private markets
- Enhancement of added value through the shift to a solutions business including pipeline design, construction, and maintenance
- Expansion of projects for electric power and steel applications and overseas projects in the Valve Systems Division
- Strengthened competitiveness through investment in CO2 emission reduction and production rationalization at the Kagaya Plant
Risks
- Risk of order volatility for large-scale projects in the Valve Systems Division (drop-off effect occurred from large-scale projects in the same period of the prior year)
- Risk of profitability deterioration due to rising prices of materials, equipment, and labor costs
- Long-term risk of declining waterworks demand due to population decline
- Uncertainty in progress estimates for construction contracts (impact on revenue recognition)
- Risk of rising raw material procurement costs due to geopolitical risks such as the Middle East situation
