Business
Inaba Seisakusho Co., Ltd. is a metal processing manufacturer founded in 1950, operating two business segments: Steel Storage Sheds and Office Furniture. In the Steel Storage Sheds business, the company manufactures and sells storage sheds, garages, and warehouses, known for its commercial slogan "Yappari Inaba, 100-nin notte mo daijobu" (Inaba After All, Safe Even With 100 People On It), and holds the top domestic market share. In the Office Furniture business, the company manufactures and sells desks, chairs, wall-mounted storage cabinets, and other products, and also handles OEM Products orders. Consolidated net sales for FY2025 (ended July 2025) were ¥41,905 million, with Steel Storage Sheds accounting for approximately 70% and Office Furniture approximately 30%. The company's primary sales channel is indirect sales through agents and distributors, and it achieves short delivery times through a nationwide network of 22 distribution centers. Sales to its largest customer, Yuasa Trading Co., Ltd., account for 28.7% of total net sales.
Business Model
Through a vertically integrated production system (over 90% in-house manufacturing ratio) that completes everything from processing coil and aluminum materials delivered directly from blast furnace manufacturers to final inspection within the same site, the company achieves both quality control and cost reduction. Products are sold through agents and distributors, supported by rapid delivery via 22 distribution centers nationwide. Steel Storage Sheds are produced on a forecast basis, while some Office Furniture is manufactured on an OEM order basis. Strengthening relationships with agents through study sessions attended by a cumulative total of over 90,000 participants serves as the source of the company's sales strength.
Company Strengths
Backed by the brand recognition of its TV commercial "Yappari Inaba, 100-nin Notte mo Daijobu" (Inaba after all—safe even with 100 people on board), the company has maintained the top market share for 50 years since starting storage shed production in 1975. In FY2025 (ended July 2025), sales of Steel Storage Sheds were ¥29,218 million, accounting for approximately 70% of total company sales, forming a stable earnings base.
The company handles everything in-house, from processing coils and aluminum materials delivered directly from blast furnace manufacturers to final inspection, with an in-house production ratio exceeding 90%. It also designs and manufactures its own dedicated processing machinery, production lines, and painting equipment, and conducts proprietary testing that exceeds JIS standards. This enables the company to achieve cost reductions while maintaining high quality simultaneously.
As of the end of FY2025 (ended July 2025), the company had zero outstanding borrowings and held cash and cash equivalents of ¥16,047 million. The equity ratio stood at 74.0% (up 2.0 percentage points year on year), and the debt redemption period was 0.3 years, indicating extremely strong financial soundness. The company has the financial capacity to fund its capital expenditures of ¥2,270 million entirely from its own funds.
ENVALITH's Perspective
Performance Trend
Over the past five fiscal years, net sales have ranged between ¥37,800 million and ¥42,414 million. In FY2025 (ended July 2025), net sales slightly declined year on year to ¥41,906 million, while operating profit fell sharply to ¥1,865 million (down 39.2% from ¥3,065 million in the prior period). For the first nine months (cumulative Q3) of FY2026 (ending July 2026), net sales were roughly flat at ¥31,451 million (down 0.6% year on year), while profitability showed a clear recovery, with operating profit of ¥1,665 million (up 8.9% year on year), ordinary profit of ¥1,986 million (up 11.8% year on year), and quarterly net profit of ¥1,397 million (up 15.1% year on year). As an external factor, sluggish personal consumption growth due to price increases is weighing on demand for Steel Storage Sheds, while robust office relocation demand is driving the Office Furniture business. Gross profit margin has improved through price revisions and thorough profitability management, and the full-year forecast (net sales of ¥42,850 million and operating profit of ¥2,460 million) remains unchanged.
Growth Strategy
Recovery of profitability and sustainable growth through production system optimization and product lineup expansion
The transfer of storage shed production to the Tomioka Plant is progressing, scheduled for completion in July 2026. Construction in progress increased by ¥1,394 million compared to the end of the previous fiscal year, with investment now at a critical stage. Following completion, improvements in profitability are expected through enhanced production efficiency and cost reduction.
Amid growing emphasis on preparedness against natural disaster risk, sales of Medium & Large Storage Sheds and other products using designated building materials have remained steady. Demand for disaster prevention measures from corporations and municipalities continued to be addressed through the cumulative third quarter of FY2026 (ending March 2026).
Against a backdrop of demand for office relocation and renovation driven by the shift to open offices and the need to secure talent, the company has been actively pursuing proposal-based sales. Segment profit surged 111.2% year on year on a cumulative basis through the third quarter of FY2026 (ending March 2026), reflecting the effects of these initiatives.
Kyoshin Co., Ltd. (Gunma Prefecture; operator of the North Kanto Distribution Center) absorbed Kato Sangyo Co., Ltd. (Niigata Prefecture; operator of the Niigata Distribution Center) effective August 1, 2025. The merger aims to rationalize business operations, strengthen sales capabilities, and improve management efficiency, and resulted in a gain of ¥69 million from the extinguishment of shares held prior to the merger, recorded in the current fiscal year.
Based on a resolution by the Board of Directors in March 2026, the company has been conducting a share buyback of up to 200,000 shares and ¥337,600 thousand, with 175,000 shares acquired cumulatively through the third quarter. The annual dividend is planned to increase from ¥42 in the previous fiscal year to ¥44. Forecasted earnings per share stand at ¥118.09.
