Business
Keiwa Incorporated is organized into two segments based on its four core technologies of Sheeting, Laminating, Coating, and Ultra Precision: the Optical Products Business (net sales of ¥16,766 million), which manufactures and sells light diffusion films "Opalus" and composite diffuser plates "Opaski" for LCD displays, and the Functional Products Business (net sales of ¥3,707 million), which handles specialty films for clean energy vehicles, medical/hygiene films, and process paper, among others. Major customers are display component manufacturers in Taiwan, China, and South Korea, with sales to its largest customer, Radiant Opto-Electronics Corporation, accounting for 48.07% of total sales. The company operates four domestic plants (including the Wakayama Techno Center) as production bases, and has sales subsidiaries in China, Taiwan, South Korea, and the United States. Listed on the Prime Market of the Tokyo Stock Exchange.
Business Model
Through ultra-precision marketing, the company directly engages with customers ranging from brand manufacturers to component manufacturers to gather detailed information, and develops, manufactures, and sells high-value-added products that match customer needs. The Optical Products Business maintains a high segment profit margin of 42.3%. In the Functional Products Business, the company is promoting the enhancement of the product portfolio's value-added mix and aims to improve profitability by concentrating management resources on the medical/hygiene and clean energy fields.
Company Strengths
In FY2025 (fiscal year ended December 2025), the Optical Products Business posted a segment profit margin of 42.3% (segment profit of ¥7,085 million on net sales of ¥16,766 million). The direct-lit mini LED liquid crystal display composite diffuser plate "Opaski" and light diffusion film "Opalus" have continued to gain share with existing customers, and the focus on high-value-added products underpins the high profit margin.
In addition to existing sites in China (Nanjing, Suzhou, Dongguan, Beijing, Shenzhen), Taiwan, South Korea, and the U.S. (California), the company opened new marketing bases in Detroit, U.S. in November 2025 and in Hanoi, Vietnam in December 2025. It is building a direct sales structure targeting Western and European customers for in-vehicle displays, while also establishing sales infrastructure to respond to China+1 demand.
R&D expenses for FY2025 (fiscal year ended December 2025) totaled ¥1,423 million. The company continues to develop products with an eye toward next-generation demand, including high-brightness, high-heat-resistant optical sheets for HUDs, optical sheets for OLEDs, the special film "ACE" for next-generation batteries, and "Meditect" for medical/hygiene applications. Total capital expenditure was ¥2,442 million, used to enhance production capacity at the Wakayama Techno Center.
ENVALITH's Perspective
Performance Trend
Following a sharp decline in profit in FY2023 (operating profit of ¥2,456 million) and a recovery in FY2024 (¥4,740 million), FY2025 saw revenue and profit decline again (net sales of ¥20,473 million, operating profit of ¥4,287 million). In Q1 of FY2026 (ending December 2026), net sales rose to ¥5,242 million (up 5.2% year on year), marking a shift toward revenue growth. Operating profit declined slightly to ¥1,188 million (down 5.8% year on year) due to an increase in SG&A expenses, but as the foreign exchange loss of ¥215 million recorded in the same period of the previous year was zero in the current period, ordinary profit improved to ¥1,252 million (up 20.1% year on year) and net profit to ¥873 million (up 9.1% year on year). The full-year forecast remains unchanged at net sales of ¥23,229 million (up 13.5% year on year) and operating profit of ¥4,403 million (up 2.7% year on year), with steady conditions in the PC market and rapid expansion of Opaski® for monitors supporting performance from both external and internal factors.
Growth Strategy
Expanding sales of high-value-added products along four axes: direct-lit Mini LED, automotive, clean energy, and new overseas customers
Against the backdrop of growing adoption of direct-lit Mini LED liquid crystal displays, the company is expanding sales of its composite diffuser sheet "Opaski®" for notebook PCs. Sales for notebook PCs and tablets in Q1 of FY2026 (ending March 2026) [Note: original states December 2026 fiscal year end] reached ¥3,323 million (up 8.5% year on year), showing steady growth.
Sales of "Opaski®" for monitors increased sharply to ¥324 million (up 159.9% year on year) in Q1 of the fiscal year ending December 2026. The growing adoption of direct-lit Mini LED liquid crystal monitors has served as a tailwind as an external factor, and adoption of the company's own products is expanding.
In Q1 of the fiscal year ending December 2026, the company established KEIWA Germany GmbH as a new consolidated subsidiary. The company aims to establish direct access to European automotive and electronics manufacturers and build a European customer base, with a focus on automotive applications.
The company is conducting active sales proposal activities focused primarily on Southeast Asia, North America, and Australia. Segment profit in the Functional Products Business improved significantly to ¥79 million (up 56.6% year on year), and the results of overseas customer acquisition activities are beginning to contribute to improved profit margins.
The company continues to promote sales of specialty film products for EVs and fuel cell vehicles. While sales of "Oplum®" have declined due to slowing growth in the EV market, overall sales of specialty films for clean energy vehicles have increased, and the company continues its product development and sales activities in anticipation of medium- to long-term demand growth.
