Business Details
Designs and constructs instrumentation, electrical, and maintenance work for new and existing buildings, and sells automatic control equipment and environment-related equipment. This core business accounts for 64.4% of consolidated net sales. Consolidated subsidiaries such as Furuno Electric Industry, Doto Autec, and Intercentral handle contracting and construction, targeting demand from urban redevelopment, labor-saving investment, and carbon-neutrality initiatives.
Recent Overview
Sales and profit both grew substantially on higher completed construction revenue from existing-building work and a surge in new-construction orders
In FY2026 (ending March 2026), the Environmental Systems Business achieved substantial growth in both sales and profit, with net sales of ¥21,709 million (up 8.6% year on year) and operating income of ¥6,075 million (up 26.8% year on year). Completed construction revenue for existing-building work drove the increase, rising to ¥8,865 million (up 17.5% year on year). Orders received surged to ¥23,337 million (up 23.5% year on year), with new-construction orders in particular expanding sharply to ¥12,195 million (up 47.1% year on year). Backlog also grew to ¥13,124 million (up 22.6% year on year), strengthening the sales base for future periods. In addition, in April 2026 the company made K.T.S. Co., Ltd. (commissioning adjustment for automatic HVAC control systems and inspection/repair of control equipment) a subsidiary, strengthening its commissioning and maintenance capabilities in the Tokyo metropolitan area.
Key Products
Growth Drivers
- Rapid expansion of new-construction orders driven by continued large-scale redevelopment projects and private-sector labor-saving and digitalization investment (orders received up 23.5% year on year; new-construction orders up 47.1% year on year)
- Increase in completed construction revenue for existing buildings (up 17.5% year on year) driven by growing demand for decarbonization and energy-saving renovation of existing buildings
- Improved visibility of next-period sales through accumulation of backlog of ¥13,124 million (up 22.6% year on year)
- Strengthened proposal capabilities and on-site engineer support systems through use of construction project data and DX promotion
- Strengthened commissioning and maintenance capabilities in the Tokyo metropolitan area through the consolidation of K.T.S. Co., Ltd.
- Enhanced response to demand for sustainable construction based on the Fourth Medium-Term Management Plan (FY2026 (ending March 2026) through FY2028 (ending March 2028))
Risks
- Risk of rising costs due to persistently high construction material prices and rising labor unit costs
- Constraints on construction capacity due to chronic shortage of skilled labor
- New-construction completed construction revenue declined slightly by 1.5% year on year (¥9,595 million), posing a risk of delayed revenue recognition due to the time lag between order receipt and completion
- Recording of impairment losses (¥49,978 million recorded in the Piping and Equipment Materials Business and ¥105 million in Corporate and Eliminations for the current consolidated fiscal year; no impairment recorded in the Environmental Systems Business)
- Risk of lower performance in the first half due to seasonality skewed toward second-half completion of construction
- Risk of downward pressure on construction investment due to deteriorating corporate earnings associated with geopolitical risk
