Business
Fukoku Co., Ltd. is a rubber products manufacturer founded in 1953, operating as a global group with 17 consolidated subsidiaries and 1 equity-method affiliate. The company operates five business segments: Functional Products (Seal Components, Wiper Blade Rubber, etc.), Anti-Vibration (Damper, Mount, etc.), Life Science (bio-related products), Metal Processing (Metal Parts for Construction Machinery), and Hose (rubber hoses for commercial vehicles). Its main customers are domestic and overseas automakers and Tier 1 suppliers, with production bases in South Korea, Thailand, Indonesia, India, China, the United States, Mexico, and other locations. Consolidated net sales for FY2026 (ending March 2026) were ¥90,025 million. The company is listed on the Prime Market of the Tokyo Stock Exchange.
Business Model
Leveraging integrated know-how spanning design, prototyping, evaluation, and mass production as its strength, the Group supplies products directly to automakers and Tier 1 suppliers both in Japan and overseas. It has built a structure in which local subsidiaries in each country sell to local customers, securing local production-for-local-consumption revenue while diversifying foreign exchange risk. In Wiper Blade Rubber, the company boasts a global share of 58% (fiscal 2025), enhancing added value through solution-oriented sales. In the Life Science Business, the company is prioritizing allocation of management resources as a high-margin growth business (operating profit margin of 24.7%).
Company Strengths
According to the Annual Securities Report, through deepening its solutions business and strengthening R&D in China, the global share of Wiper Blade Rubber expanded from 50% in FY2024 to 58% in FY2025. The company has achieved new entry into Chinese local automakers, and is also making progress in expanding sales to European manufacturers in collaboration with Chinese wiper system makers.
The company operates manufacturing sites in South Korea, Thailand, Indonesia, India, Vietnam, China (Shanghai, Dongguan, Qingdao, Nanjing), the United States, and Mexico, and newly established FKC America Inc. in Virginia, USA in December 2025. Its customer base and procurement network, built on over 70 years of local production experience, form a competitive advantage that is difficult to replicate in a short period.
R&D expenses for the fiscal year under review increased from ¥2,272 million to ¥2,383 million. The company has been accumulating intellectual property across multiple fields, including international patent applications and domestic patent acquisitions for Thermal Gap Filler, two applications for soft grippers, two for space-related anti-vibration rubber, and international patent applications for silicone materials for new energy applications. It has also achieved technology selection for JAXA's Space Strategic Fund Program.
ENVALITH's Perspective
Performance Trend
Consolidated net sales for FY2026 (ending March 2026) came to ¥90,025 million (up 0.4% year on year), a slight increase. While the Functional Products, Life Science, and Hose businesses performed solidly, the Metal Processing Business declined 25.8% year on year due to selective focus aimed at improving profitability. Operating profit fell sharply to ¥3,806 million (down 19.4% year on year), impacted by difficulty absorbing rising raw material and labor costs, as well as the reversal effect from a one-time cost-of-sales reduction related to misconduct in the prior fiscal year (¥423 million). As an external factor, the continued rise in raw material and labor costs weighed on profitability. Profit attributable to owners of parent came to ¥1,144 million (down 61.0% year on year), directly hit by an impairment loss of ¥918 million in the Anti-Vibration Business. Operating cash flow improved to ¥8,044 million (versus ¥6,631 million in the prior fiscal year), indicating that cash generation capability was maintained.
Growth Strategy
Prioritizing revenue expansion and improved capital efficiency, the company is advancing the strengthening of existing businesses, the expansion of new growth businesses, and the reform of its ESG management foundation.
Focused sales expansion efforts are being directed toward orders for Thermal Gap Filler and China local wiper manufacturers. In FY2026 (ending March 2026), Functional Products segment sales grew steadily to ¥42,689 million (up 3.7% year on year). Expansion into industrial fields such as precision seals for semiconductor manufacturing equipment also continued.
In FY2026 (ending March 2026), FKC America Inc. was newly established, marking a full-scale expansion into North America. In India, the fiscal year-end of Fukoku India Private Limited was unified to March 31 to strengthen consolidated management. Efforts are underway to expand orders for Dampers and other products in the Indian market.
Orders for bio-related products remained solid (FY2026, ending March 2026 sales of ¥1,041 million, up 6.2% year on year). Efforts are being advanced toward clinical adoption of the Drug-Resistant Bacteria Test Chip in preparation for insurance coverage, along with strengthening culture medium development capabilities through joint research with Osaka University and Kanazawa Medical University.
Withdrawal from unprofitable components is being pursued to improve profitability. In FY2026 (ending March 2026), sales declined 25.8% year on year to ¥3,961 million, and the segment remained in a loss position with a segment loss of ¥201 million. Absorbing the rising ratio of raw material and labor costs remains an ongoing challenge.
The company sold part of its policy shareholdings (recording a gain on sale of securities of ¥135 million), conducted a tender offer for treasury shares (acquiring 1,904,600 shares for ¥3,163 million), and retired 1,700,000 treasury shares. The annual dividend is planned to increase from ¥85 (FY2026, ending March 2026) to ¥100 (forecast for FY2027, ending March 2027). At the Board of Directors meeting held on May 15, 2026, the basic dividend policy was revised.
