Business
Nippon Can Co., Ltd. is a metal can specialist manufacturer founded in 1925, comprising the company itself and its subsidiary Shinsei Seikan Co., Ltd. (based in the Kansai region). Its core products are two pillars: 18L Cans (pail cans) and Art Cans, and the Metal Can Manufacturing and Sales Business posted sales of ¥11,278 million in FY2026 (ending March 2026). The 18L Can business captures domestic demand mainly for the oil and food sectors, while Art Cans, positioned as a high-value-added product, serve as the driving force behind profitability improvement. Major customers include Seibu Yoki Co., Ltd. (16.9% of sales) and Meiji Co., Ltd. (7.3%). Raw materials are mainly procured from Itochu Marubeni Steel Inc., a related party. The company also holds a Real Estate Leasing Business (sales of ¥163 million), which serves as the group's sole stable source of operating profit.
Business Model
The primary revenue source is the made-to-order manufacturing and sales of 18L Cans and Art Cans, whereby steel and other raw materials are procured and processed and printed at the company's own factories before delivery to customers. The company has a mechanism to reflect cost fluctuations in sales prices through price pass-through. As a secondary revenue source, it operates a leasing business for its self-owned real estate (including a steel-framed three-story building in Saitama City, among others), generating stable operating profit of ¥83 million that is less susceptible to economic fluctuations. Capital expenditure funds are procured mainly through long-term borrowings from financial institutions.
Company Strengths
Founded in 1925, the company celebrated its 100th anniversary in 2025 as a can-manufacturing specialist. Its two-site structure—the Company itself (Kanto) and Shinsei Seikan Co., Ltd. (Kansai)—enables cross-regional production and OEM supply. Its long-accumulated can-manufacturing expertise has built a foundation of customer trust, with a track record of continuous transactions with major customers such as Seibu Yoki and Meiji.
New manufacturing equipment for Art Cans resumed operation in May 2025. In FY2026 (ending March 2026), Art Can sales reached ¥2,054 million (up 8.1% year on year), with production volume expanding to 113.5% of the prior year. Production capacity for high-value-added products is undergoing a full-scale recovery, laying the groundwork for improved profitability through an enhanced product mix.
The leasing business for company-owned real estate consistently posted sales of ¥163 million and operating profit of ¥83 million in FY2026 (ending March 2026). It has continuously generated operating profit exceeding depreciation expenses (approximately ¥39 million), serving a cash-generating function that partially offsets losses in the Metal Can Manufacturing and Sales Business. In the fiscal year under review, ¥97 million was also invested in fixed assets.
ENVALITH's Perspective
Performance Trend
Revenue for FY2026 (ending March 2026) rose only slightly to ¥11,442 million (up 1.6% year on year), while operating loss came to ¥307 million (compared with a loss of ¥541 million in the previous period), ordinary loss was ¥283 million (compared with a loss of ¥476 million in the previous period), and net loss attributable to owners of the parent was ¥346 million (compared with a loss of ¥335 million in the previous period). The loss margin narrowed at the operating and ordinary income levels, but the net loss widened. External factors such as heightened tension in Japan-China relations, the impact of U.S. trade policy, yen depreciation, and surging energy prices weighed on earnings. For FY2027 (ending March 2027), the company forecasts revenue of ¥11,525 million and an operating loss of ¥104 million, with a return to profitability expected from FY2028 (ending March 2028) onward.
Growth Strategy
Aiming for profitability in FY2028 (ending March 2028) through production consolidation, cost structure reform, and stabilization of new Art Can equipment operations
Fixed cost reductions will be phased in through production consolidation, including the closure of the Chiba Plant. In FY2026 (ending March 2026), a plant closure loss of ¥60 million was recorded, and full-scale realization of production efficiency improvements and fixed cost reduction effects is expected from FY2027 (ending March 2027) onward.
Art Can sales reached ¥2,054 million, up 8.1% year on year, but stabilizing operations of the new equipment continues to require time. The company is progressively obtaining customer approvals for new products and plans to transition to a full-scale mass production and sales system.
The company aims to improve gross profit margin by expanding the proportion of high-value-added Art Cans (18.2% in the current period) and reviewing low-profitability products. Gross profit margin for FY2026 (ending March 2026) improved to 9.6% (from 7.6% in the prior period), showing steady progress.
The company aims to diversify its revenue base through the development and commercialization of high-value-added products and the acquisition of new customers. Currently, obtaining customer approvals for new products is taking longer than expected, and both sales volume and profitability are projected to fall short of the initial plan.
