Business
Asahi Concrete Industries Co., Ltd., founded in 1923, is a manufacturer specializing in Precast Concrete Products listed on the Tokyo Stock Exchange Standard Market. The company operates two segments: the Concrete-Related Business, whose core products include hume pipes, box culverts, common utility ducts, earthquake-resistant fire cisterns, and rainwater storage tanks, and the Real Estate Business, which involves the leasing of company-owned real estate. Its main customers are public works ordering entities in fields such as sewerage, roads, and disaster prevention, and it provides an integrated offering of product supply, construction work, and materials sales through a nationwide network of multiple plants and sales offices. The company conducts sales and purchasing transactions in the Concrete-Related Business with Nihon Hume Co., Ltd., another affiliated company.
Business Model
The Precast Concrete Products segment (net sales of ¥4,528 million in FY2026 (ending March 2026)) serves as the core profit driver, complemented by the Construction segment (¥393 million) and the Other segment (¥2,671 million), which handles the Purchase and Sale of Construction and Attachment Materials. The company secures profits through selective order-taking to manage profitability and through production efficiency improvements, while winning orders via design-integration activities utilizing CIM (3D spatial models, etc.). The Real Estate Business (¥43 million), though small in scale, provides stable rental income.
Company Strengths
Founded in 1923, the company marked its 100th anniversary in 2023. In 1966, it developed Japan's first PC box culvert, and has since grown to the point where its technology is now shared across 34 companies nationwide as the Japan PC Box Culvert Products Association. It has developed proprietary construction methods such as the "TB (Touch Bond) Method" and "ECO-C・L Method," and holds numerous intellectual property rights.
The company operates multiple plants across Akita, Sendai, Ibaraki, Kanto, Fuchu, Kasugai, Ena, Shiga, Koto, Wakayama, Hyogo, and other locations, along with sales offices in Saitama, Chiba, Yokohama, Kanazawa, Hanshin, Nagoya, Sendai, and other areas nationwide. It has built an integrated system covering manufacturing, sales, construction work, and materials supply, giving it a geographic infrastructure that competitors find difficult to replicate in a short period.
As of the end of FY2026 (ending March 2026), net assets stood at ¥12,712 million, with an equity ratio of 75.8%, maintaining an extremely healthy financial structure. Cash and cash equivalents totaled ¥2,559 million, and the company also holds long-term deposits, ensuring financial stability even amid capital investment needs and rising raw material prices.
ENVALITH's Perspective
Performance Trend
Net sales expanded 18.1% over five fiscal years, from ¥6,467 million in FY2022 (ended March 2022) to ¥7,637 million in FY2026 (ending March 2026). Operating income increased 66.7% over the same period, from ¥366 million to ¥610 million, and the operating margin improved from 5.7% to 8.0%. In FY2026, the Other segment (Purchase and Sale of Construction and Attachment Materials) led growth with an 18.3% year-on-year increase in sales, advancing diversification of the sales mix. As external factors, promotion of the national resilience plan and demand for construction of private-sector logistics facilities provided tailwinds, while surging raw material and energy prices continued to exert cost pressure. It should be noted that operating cash flow declined 56% year on year to ¥388 million due to an increase in trade receivables.
Growth Strategy
Promoting a three-pronged approach of expanding orders through ICT and 3D technology utilization, proposing precast conversion, and reducing costs through equipment renewal
The sales and design departments are jointly promoting design integration activities that make full use of digital technologies such as 3D spatial models and 3D printer models. Market development outside existing markets is also being advanced through proposals to convert cast-in-place concrete structures to precast concrete. Revenue growth was achieved in FY2026 (ending March 2026), reflecting the results of these activities in sales.
Equipment renewal at key plants is being carried out sequentially to improve quality, address rising raw material costs, and enhance productivity and appropriate cost management. Acquisitions of tangible and intangible fixed assets in FY2026 (ending March 2026) increased significantly to ¥490 million from ¥272 million in the previous fiscal year, indicating accelerating investment.
The company continues to focus on selective order acceptance considering profitability, along with reducing SG&A expenses and strengthening inventory management. The operating margin on sales in FY2026 (ending March 2026) improved to 8.0% from 7.7% in the previous fiscal year, reflecting the results of efforts to strengthen profitability. An operating margin level of 8.0% is also expected to be maintained in FY2027 (ending March 2027).
The company steadily implements, as a foundation for its business activities, the appointment and development of diverse core personnel who will lead the next generation, year-round hiring of young and mid-career talent, and improvement of the workplace environment. As labor shortages become an industry-wide challenge, securing and retaining talent is directly linked to maintaining medium- to long-term competitiveness.
