Business Details

This segment handles water supply and drainage/sanitation equipment work, air conditioning equipment work, renovation work (including miscellaneous drainage pipe lining work), heating/cooling and hot water supply work for multi-family housing, and GHP construction and maintenance. Main customers include general contractors, regional construction firms, and multi-family housing owners. Under the medium-term management plan "Triple S," it is positioned as a new core business alongside the gas pipeline business, responsible for reducing dependence on a single customer through strengthened comprehensive order-taking and construction capabilities.

Recent Overview

Cumulative 3Q sales surged 69.8% year-on-year, with ordinary income turning positive from a loss

For the cumulative nine months of FY2026 (ending March 2026) (April to December 2025), sales were ¥4,625 million (up 69.8% year-on-year) and ordinary income was ¥252 million (versus an ordinary loss of ¥170 million in the same period of the prior year), marking substantial improvement. Orders for water supply/sanitation equipment work and facility air conditioning work for multi-family housing and other properties trended very favorably, while increased completions of large-scale factory maintenance projects and steady progress in the GHP maintenance business also contributed. Orders received for the period totaled ¥7,011 million (more than doubling from ¥3,324 million in the same period of the prior year), and the order backlog built up to ¥5,243 million, raising expectations for sales contribution in future periods.

Key Products

service
Water Supply and Sanitation Equipment Work

Water supply and sanitation equipment work for multi-family housing, commercial facilities, factories, and other buildings. The company has undertaken many large-scale projects with long construction periods, creating a structure where accumulated order backlog directly translates into future sales. Orders have trended very favorably in the cumulative 3Q.

service
Air Conditioning Equipment Work

Air conditioning equipment work for office buildings, factories, commercial facilities, and other buildings. Includes GHP (gas heat pump air conditioner) work, with orders trending favorably against a backdrop of rising demand for energy-saving measures.

service
Renovation Work

General renovation work for existing buildings, including miscellaneous drainage pipe lining work. The company is promoting increased estimating staff and order acquisition from diagnostic survey projects, against a backdrop of expanding maintenance and renewal markets for existing buildings.

service
Multi-Family Housing Heating/Cooling and Hot Water Supply Work

Hot water supply and heating equipment work for multi-family housing. Orders remain solid, coordinated with expanded sales of environmental products such as hybrid water heaters.

service
GHP Maintenance Business

Maintenance services covering periodic inspection, repair, and renewal of existing GHP (gas heat pump air conditioner) units. Expected to contribute stable revenue as a recurring stock-type income stream, having progressed steadily in both the prior and current periods.

Growth Drivers

  • Sharp increase in orders for water supply/sanitation equipment work and air conditioning work for multi-family housing and facilities (cumulative 3Q orders received more than doubled year-on-year)
  • Increase in completions of large-scale projects in factory facility maintenance work (underpinned by resilient corporate capital expenditure appetite)
  • Steady expansion of the GHP maintenance business, building up recurring stock-type revenue
  • Advancement of comprehensive order-taking and construction system development under the policy of establishing this as a new core business in the medium-term management plan "Triple S"
  • Steady trends in the existing building reform/renovation market and contribution from energy-saving subsidy policies

Risks

  • Risk of delayed progress on large-scale projects with long construction periods (thorough schedule management remains a challenge)
  • Concerns over rising construction costs and deteriorating profitability due to persistently high material prices and rising labor costs
  • Chronic shortage of engineers and construction personnel (worsening labor shortage across the construction industry as a whole)
  • Continued sluggishness in housing starts (2024 saw a second consecutive year of decline, down 27,525 units year-on-year to 792,098 units)
  • Risk of sales volatility in renovation work due to irregular timing of large-scale project completions
