Business
Iida Group Holdings is a holding company with six operating subsidiaries under its umbrella: Ichiken, Iida Sangyo, Tohei Jutaku, Tact Home, Earthone, and IDI Home. It boasts an overwhelming supply scale in the domestic detached housing development market, with 36,989 units sold in the Detached Housing Development Business and revenue reaching ¥1,508,864 million in FY2026 (ending March 2026). Its main target customers are first-time homebuyers in their 20s to 30s, to whom it supplies reasonably priced housing with excellent earthquake resistance and environmental performance nationwide. While centered on detached housing development, the group is expanding into Condominium Development Business, Contract Construction Business, Real Estate Leasing Business, Lumber Manufacturing Business, and Overseas Business.
Business Model
Each operating company conducts agile land acquisition, construction, and sales based on the supply-demand characteristics of each area, leveraging economies of scale to achieve cost competitiveness. After sales, the Group builds up stock-type revenue through maintenance and renovation businesses utilizing a cumulative customer base of approximately 800,000 units. In addition, the Group aims to diversify revenue sources through detached housing rental, investment real estate, condominium development, overseas business, and other areas, thereby building a structure with greater resilience to economic fluctuations.
Company Strengths
Six operating companies each cover the market with their own price ranges and specifications, recording 36,989 detached housing units sold and revenue of ¥1,218,583 million in FY2026 (ending March 2026). By respecting each company's autonomy while operating under a unified group policy, the group achieves comprehensive coverage of diverse customer needs and maximizes market coverage.
The renovation and maintenance business is expanding steadily, leveraging the group's cumulative customer base of approximately 800,000 units. In FY2026 (ending March 2026), Contract Construction Business revenue was ¥83,521 million (up 6.5% year on year), with increased orders for high-margin renovation work contributing to higher revenue and profit. This contributes to strengthened resilience against economic fluctuations as a source of recurring, stock-type revenue.
The group has previously obtained the highest ratings in all four categories of housing performance evaluation, resulting in limited impact from the reduction in scope of the Building Standards Act's Article 4 special exception, which took effect in April 2025. While competitors have seen significant declines in housing starts, the group's continued supply capability has been maintained, positioning it to benefit from the resulting improvement in supply-demand balance.
ENVALITH's Perspective
Performance Trend
Revenue trended sideways at roughly ¥1,439,000 million in FY2023 and FY2024 after rising from ¥1,386,991 million in FY2022, before accelerating to ¥1,459,639 million in FY2025 and ¥1,508,864 million in FY2026. Operating profit, which peaked at ¥153,306 million in FY2022, declined to ¥59,174 million in FY2024, but then recovered significantly for two consecutive periods, reaching ¥80,452 million in FY2025 and ¥94,444 million in FY2026. As an external factor, resilient housing demand and improving supply-demand balance, mainly in the greater Tokyo metropolitan area, pushed up profit margins. Meanwhile, the sharp increase in inventory (¥966,039 million) and the shift to negative operating cash flow reflect an aggressive land acquisition strategy, and the focus now turns to whether the company can achieve its FY2027 (ending March 2027) forecasts of ¥1,663,000 million in revenue and ¥103,600 million in operating profit.
Growth Strategy
Aiming for ROE of 10% or more and a detached housing dependency ratio of 70% in FY2030 (ending March 2030), the company is advancing core business reinforcement and business diversification
The company thoroughly pursues agile land acquisition and sales that account for regional supply-demand characteristics and inventory conditions, continuing to maintain appropriate inventory levels and refine area strategies. In FY2026 (ending March 2026), revenue from the Detached Housing Development Business remained solid at ¥1,218,583 million (up 0.8% year on year), contributing to improved profit margins.
The company newly consolidated 25 US subsidiaries, including Arnest One America, Inc., from FY2026 (ending March 2026), putting its overseas housing business into full operation. Revenue from the Earthone Group's "Other" category expanded sharply, up 1,642.6% year on year. Non-development businesses such as Condominium Development, Real Estate Leasing, and Hotels also expanded steadily, with the group's overall "Other" revenue reaching ¥111,468 million (up 34.4% year on year).
The company is systematically advancing the establishment of a financial structure capable of sustaining stable business continuity even amid supply chain disruptions caused by natural disasters, geopolitical risks, and similar events. It has been disclosed that the target level has been largely achieved, establishing a structure that would allow the company to move quickly to offense in the event of an emergency. Cash and cash equivalents at period-end stood at ¥390,743 million.
The company promotes, as a key management priority, the dual pursuit of "realizing a living environment where everyone can live safely, comfortably, and healthily" and "contributing to global environmental conservation and clean energy." While upholding the group's business concept of "Making it normal for everyone," the company aims to enhance corporate value over the medium to long term by strengthening its ESG initiatives.
