Business

Nitto Seimo Co., Ltd. is a long-established fishing net manufacturer founded in 1910, comprising the company and 14 subsidiaries. In the Fishery-Related Business (net sales of ¥17,447 million), the group operates a vertically integrated business spanning fishing net manufacturing and sales, marine product procurement and sales, and Set-Net Fishery & Fishing Ground Management Guidance, with overseas local subsidiaries in Chile, Thailand, and Peru. In the Land-Based Related Business (net sales of ¥4,150 million), the group handles Wildlife Damage Prevention Nets, nets for sports facilities, and Insect-Proof Nets & Agricultural Materials. Major customers include fishery operators, aquaculture businesses, sports facilities, and agricultural stakeholders both in Japan and overseas, and the company holds an industry-leading position, listed on the Tokyo and Nagoya Stock Exchanges. In February 2024, the new Fukuyama plant was completed, strengthening the production system.

Business Model

In the Fishery-Related Business, the company sells self-manufactured fishing nets and fishery materials to fishermen while also capturing revenue from the catch landing and sales operations of its Set-Net Fishery & Fishing Ground Management Guidance subsidiary, adopting a vertically integrated business model. In the Land-Based Related Business, the company provides high-value-added services through Taito Co., Ltd., combining expanded sales of original products with installation work. During periods of rising raw material costs, the company maintains competitiveness and secures profitability through a structure of continuous price pass-through and shortened lead times enabled by appropriate inventory management.

Company Strengths

For over 100 years since its founding in 1910, the company has specialized in fishing net manufacturing, continuously deepening its manufacturing technologies for knotless nets, twisted nets, ropes, and more. It promotes new-material fishing net development and fishing net recycling research through industry-government-academia collaboration, investing ¥186 million in R&D expenses during the current consolidated fiscal year. Its technical superiority as an industry cornerstone forms a barrier to entry.

Beyond fishing net manufacturing and sales, the company holds set-net fishery subsidiaries (Onsenzu Teichi Co., Ltd., Yoshida Fishery Co., Ltd., and Shoji Masakichi Shoten Co., Ltd.) under its umbrella, giving it a structure in which strong catch volumes directly translate into profit. In the Fishery-Related segment, profit for the fiscal year ended April 2025 reached ¥384 million (up 16.5% year on year), reflecting the effect of vertical integration on business performance.

The company has manufacturing subsidiaries in Chile and Thailand and a sales subsidiary in Peru, with purse seine net exports to Asia also progressing steadily. Domestically, the Land-Based Related Business (net sales of ¥4,150 million) has grown rapidly, backed by structural expansion in demand for Wildlife Damage Prevention Nets, achieving a 7.1% year-on-year increase in sales and a 187.2% year-on-year increase in segment profit, thereby diversifying risk from dependence on the fishery business.

ENVALITH's Perspective

In FY2026 (ending March 2026)(the fiscal year ending April 2026), net sales reached ¥22,104 million (up 2.3% YoY), marking five consecutive years of sales growth, but operating profit deteriorated sharply to ¥554 million (down 18.5% YoY). The main causes were the failure to level out production and rises in raw material costs and labor costs. The operating profit margin remained at a low 2.5%, and the gap versus the management target of a 6% ordinary profit margin remains significant. The forecast for FY2027 (ending April 2027) also anticipates a further decline in operating profit to ¥500 million (down 9.8% YoY), making improvement of the cost structure an urgent priority.

Operating cash flow for FY2026 (ending March 2026)(the fiscal year ending April 2026) turned sharply negative at ¥-96 million, a significant deterioration from ¥993 million in the previous period. The main causes were a ¥448 million increase in trade receivables and a ¥512 million decrease in trade payables. Short-term borrowings surged to ¥11,564 million (from ¥9,983 million in the previous period), and total interest-bearing debt has swelled to over ¥17,578 million. Amid a rising interest rate environment (an external factor), interest expenses increased by ¥64 million YoY to ¥195 million, continuing a pattern in which rising financial costs squeeze profits. The equity ratio remains at a low 25.3%.

Ordinary profit for FY2026 (ending March 2026)(the fiscal year ending April 2026) rose to ¥963 million (up 16.2% YoY), and profit attributable to owners of parent increased to ¥680 million (up 27.2% YoY). However, non-operating income included highly volatile and one-off items such as ¥208 million in foreign exchange gains, ¥79 million in foreign tax refunds, and ¥60 million in equity-method investment gains, raising doubts about the sustainability of the ordinary profit increase given that core operating profit declined. The forecast for FY2027 (ending April 2027) anticipates a sharp decline in ordinary profit to ¥450 million (down 53.3% YoY), indicating that the company itself recognizes the drop-off of these temporary gains.

Growth Strategy

Three pillars: overseas sales target of ¥3.0 billion, expanded sales of high-value-added products, and strengthening of Land-Based Related Business

Exports to Asia in the Purse Seine Net segment continued to progress smoothly in FY2026 (ending April 2026). While leveraging existing bases in Chile, Thailand, Peru, and other locations, the Company is advancing the realization of new projects toward the target of ¥3.0 billion in overseas sales. In FY2026 (ending April 2026), the Company also acquired shares of a subsidiary (cash inflow of ¥63 million), resulting in a change in the scope of consolidation.

Orders for installation work such as Wildlife Damage Prevention Nets and athletic nets remained strong, with Land-Based Related Business sales reaching ¥4,315 million in FY2026 (ending April 2026), up 4.0% year on year. The Company continues to pursue differentiation and improved profitability through expanded sales of the Group's original products. However, challenges remain, as segment profit declined 18.4% year on year due to rising personnel and material costs.

The Company has continued to pursue price revisions in response to rising raw material and personnel costs; however, in FY2026 (ending April 2026), it was unable to achieve production leveling, resulting in operating profit falling 18.5% year on year and missing the target. In FY2027 (ending April 2027), further cost increases are expected due to rising procurement prices and interest rates, making improvement in production efficiency an urgent priority.
