Business

Daiken Co., Ltd. is a manufacturer of Construction-related Products founded in 1924 (Taisho 13). Its core business is the manufacturing, sales, and installation of Architectural Hardware (Hanger Rails, etc.) such as door hangers, Exterior Products (Bicycle Racks, Storage Sheds, etc.) including storage sheds, bicycle racks, and garbage collection enclosures, and Exterior Building Materials (Using Aluminum Extrusions). Its customer base is broad, spanning multifamily housing, public works projects, and corporate capital investment, with sales to its major business partner Sugita Ace Co., Ltd. accounting for approximately 19.8% of the total. Headquartered in Osaka, the company operates a nationwide network of branches and sales offices, and has built an integrated production system through its own factories in Muroran, Narita, Jusso, and elsewhere. As a secondary business, the company also engages in Real Estate Leasing, including Studio Apartment Leasing and rental retail space. The company is listed on the Standard Market of the Tokyo Stock Exchange.

Business Model

In the Construction-related Products business, the company promotes in-house production at its own factories (Muroran, Narita, Toka, etc.) while supplying products to construction companies and distributors through branches and sales offices nationwide. Construction-related Products account for approximately 98% of net sales, with the remaining approximately 2% coming from Real Estate Leasing. The company emphasizes marginal profit and the ordinary profit margin on net sales as key profitability management indicators, and aims to improve profitability through the provision of value-added products and price revisions.

Company Strengths

As of the end of FY2025 (ending February 2025), the company had zero outstanding borrowings, with an equity ratio of 83.7% (maintained at a consistently high level since 81.1% in FY2021, ending February 2021). Net assets stood at ¥13,206 million, and overdraft agreements totaling ¥3,050 million were secured with multiple financial institutions. Financial soundness is exceptionally high within the industry, providing both strong investment capacity and resilience against crises.

Since its founding in 1924, the company has continuously conducted R&D across three fields: Architectural Hardware, Exterior Products, and building materials. R&D expenses in FY2025 (ending February 2025) totaled ¥183 million (Hardware: ¥98 million, Exterior: ¥50 million, Building Materials: ¥34 million). The company has established a suitable-location production and nationwide sales system, combining multiple factories in Muroran, Narita, and Juso with a nationwide network of branches and sales offices.

In FY2025 (ending February 2025), production volume in the Exterior Products segment increased 108.9% year on year, the highest growth among all product categories. This was driven by capturing demand for bicycle racks for multi-family housing and strengthening production capacity through active capital investment in garbage collection storage units. Total capital investment in FY2025 (ending February 2025) amounted to ¥428 million, with continued investment in production machinery and factory buildings.

ENVALITH's Perspective

In Q1 FY2027 (ending February 2027) (March–May 2026), the company posted net sales of ¥2,764 million against an operating loss of ¥32 million, ordinary loss of ¥29 million, and quarterly net loss of ¥30 million, marking a loss-making start. Increased fixed costs associated with investment in the Muroran plant pushed down the gross profit margin. The full-year earnings forecast anticipates a substantial improvement, with net sales of ¥13,000 million (+12.4% year-on-year) and operating income of ¥535 million (+107.8% year-on-year), but while the Q1 progress rate for net sales stood at 21.3%, profit was in the red, making the achievability of the forecast—premised on a concentration of earnings in the second half—the most notable point of focus.

As an external factor, prices of raw materials such as aluminum ingots and naphtha-related auxiliary materials continue to rise, keeping the cost environment challenging. A concern is that supply uncertainty for materials and auxiliary materials has increased due to the impact of the situation in the Middle East, and construction delays and postponements of construction starts have begun to occur. Continued yen depreciation is also a factor pushing up the cost of imported raw materials. Should these external headwinds fall short of the assumptions underlying the full-year forecast, there is a risk of a downward revision to the earnings forecast.

According to Q1 segment information, against a combined segment profit of ¥71 million—comprising ¥50 million from Construction-related Products and ¥21 million from Real Estate Leasing—the adjustment amount for company-wide expenses (general and administrative expenses not allocated to each segment) was a substantial ¥104 million, resulting in a consolidated operating loss of ¥33 million. Whether the sales expansion and cost reductions from integration synergies with Miki Seisakusho can absorb these company-wide expenses will be key to improving the earnings structure over the medium term.

Growth Strategy

Twin-pronged strategy to improve the profit structure through synergies with Miki Seisakusho Co., Ltd. and enhanced in-house production at the Muroran plant

The plant building and production equipment at the Muroran plant, in which investments were made in the previous fiscal year, have begun operations. The company has started to enhance in-house production and reduce transport costs through local production for local consumption, and full-scale cost reduction effects are expected to materialize. System unification and business consolidation are also being pursued in parallel.

The company is building a cooperative framework with Miki Seisakusho, which became a wholly owned subsidiary in June 2025, aiming to strengthen sales and production capabilities and expand market share. In the first quarter, this contributed in part to increased orders for bicycle racks, pits, gratings, etc.

The company is actively pursuing new market development and PR for new products, including exhibiting at trade shows it has not previously participated in. It is working to expand demand in new markets through product development and application proposals that respond to needs for labor savings and workforce reduction.

The company maintains a high occupancy rate for Studio Apartment Leasing, securing stable rental income. For Corporate Tenant Leasing, it is considering measures to effectively utilize vacant tenant space. The segment recorded a first-quarter segment profit of ¥21 million, functioning as a stable source of earnings.
