Business
The Nakayama Steel Works Group is a long-established steel manufacturer founded in 1919. Since suspending its blast furnace and converter operations in 2002, the company has specialized in electric-furnace steel production. In its core Steel segment, the company manufactures and sells Primary Steel Products (Crude Steel & Rolled Steel) and Secondary Processed Steel Products (Processed Steel Materials) using electric furnaces, accounting for over 98% of net sales. The Engineering segment handles manufacturing and sales of Steel Fish Reefs & Propagation Reefs and rolls, while the Real Estate segment covers leasing, sales, and brokerage. Sales to Hanwa Co., Ltd., a major shareholder, account for approximately 20% of the total, and the group has built a vertically integrated business structure encompassing sales companies, a shipping company, and processing companies. Listed on the Prime Market of the Tokyo Stock Exchange.
Business Model
Using steel scrap as the main raw material, the company melts it in electric furnaces and continuously casts it, then manufactures steel materials and processed products through hot-rolling and processing operations. Sales are conducted through consolidated subsidiaries Nakayama Tsusho and Sanei Shoji, while transportation is handled by Sanei Kaiun. Earnings are structured around the spread between steel product sales prices and raw material/electricity costs, making the business directly exposed to market fluctuations. Rental income from the Real Estate segment functions as a stable supplementary source of earnings.
Company Strengths
The company is one of a limited number of manufacturers capable of producing electric arc furnace steel, which emits approximately one-quarter the CO2 of blast furnace steel, while also retaining blast furnace and converter technology. Even after suspending blast furnace operations in 2002, it has maintained this technical knowledge, which serves as a differentiating factor versus competitors in expanding the quality and applications of electric arc furnace steel products.
As of the end of FY2026 (ending March 2026), interest-bearing debt stood at ¥8,515 million against cash and cash equivalents of ¥23,225 million, placing the company in a significant net cash position. Net assets totaled ¥109,149 million and total assets ¥152,371 million, maintaining a high equity ratio and ensuring financial stability even during phases of large-scale investment.
The group comprises consolidated subsidiaries in manufacturing (Nakayama Steel Works and Misen Shear), sales (Nakayama Tsusho and Sanei Shoji), maritime transport (Sanei Kaiun), and Real Estate (Nakayama Kosan), forming an integrated intra-group supply chain from raw material procurement through product delivery. The company has also implemented centralized group cash management via a CMS to improve operational efficiency.
ENVALITH's Perspective
Performance Trend
Revenue peaked at ¥188,514 million in FY2023 and has declined for three consecutive fiscal years, reaching ¥148,306 million in FY2026 (ending March 2026), down 12.4% year on year. Operating profit fell approximately 64% over the same period, from ¥13,644 million to ¥4,911 million. In FY2026 (ending March 2026), the suspension of electric furnace operations following the No. 5 substation accident in September 2025 (production volume down approximately 60% year on year) resulted in approximately ¥1,600 million in additional costs, compounded by a downward trend in steel market conditions due to inflows of cheap imports from China, sluggish domestic demand from the construction and manufacturing sectors, and persistently high scrap steel prices. On the other hand, operating cash flow improved significantly to ¥15,274 million (from ¥7,346 million in the prior period), supported by a decrease in inventories and the collection of trade receivables. The cash balance grew to ¥23,225 million.
Growth Strategy
Aiming to transform the long-term earnings structure centered on new electric arc furnace investment, the Nippon Steel joint venture, and the Yodoko alliance
Established a joint venture (a consolidated subsidiary of the Company) on April 1, 2026, for the purpose of constructing, owning, and leasing new electric arc furnace equipment. Through capacity expansion and improved unit costs enabled by state-of-the-art equipment, the Company aims to realize its long-term vision (ordinary income of ¥10 billion or more in FY2030 and ¥13 billion or more in FY2033).
Entered into a basic agreement in December 2025 aimed at strengthening the collaborative relationship to expand applications for electric arc furnace steel products. Discussions are underway toward concluding the formal agreement. The initiative aims to build a sales foundation ahead of the startup of the new electric arc furnace.
Utilizing the newly established Kanto relay depot, the Company aims to expand its sales area and improve sales prices and sales volume through enhanced logistics efficiency. This initiative is positioned as one of the drivers of the projected recovery in net sales for FY2027 (ending March 2027) (¥157,000 million, up 5.9% year on year).
The Company is promoting expanded sales of high-value-added products and strengthening its processing capabilities by highlighting the environmental advantages of electric arc furnace steel, whose CO2 emissions are said to be roughly one-quarter those of blast furnace steel. This initiative leverages the growing societal demand for carbon neutrality and a circular economy as a business opportunity.
