Business
Koikeya Co., Ltd. is a long-established domestic snack food manufacturer that began producing and selling potato chips in 1962. The company owns a diverse range of brands including "Koikeya Pride Potato," "Karamucho," and "Scorn," and manufactures products at six of its own factories in Japan. Its main customers are domestic general consumers, and it utilizes distribution networks through trading companies such as Marubeni and Mitsubishi Corporation. Overseas, the company operates subsidiaries in Taiwan, Vietnam, Thailand, and the United States, and is expanding its business centered on the global brand "Karamucho." Nissin Foods Holdings Co., Ltd., which holds 45.1% of issued shares, is the parent company, and the two companies have built a collaborative relationship in areas such as development, procurement, production, and overseas business.
Business Model
The company manufactures snack confectionery at six domestic in-house factories and sells them to retailers through trading companies such as Marubeni and Mitsubishi Corporation. It aims to raise unit prices and improve profit margins through concentrated investment in high-value-added brands and continuous renewal of products. Overseas, in addition to manufacturing and sales through local subsidiaries, the company combines this with exports from domestic factories to promote global brand expansion and diversify earnings.
Company Strengths
The company holds multiple brands that have become established in the market over decades, including 'Koikeya Potato Chips' (1962), 'Karamucho' (1984), 'Scorn' (1987), and 'Polinky' (1990). These brands have maintained and expanded sales through continuous renewals and anniversary campaigns, forming entry barriers as brand assets that competitors cannot easily replicate in a short period.
In addition to six domestic plants—Kanto, Kanto No. 2, Kanto No. 3, Chubu (operational from December 2025), Kyoto, and Kyushu Aso—the company owns an overseas proprietary plant in Vietnam. Total capital expenditure for FY2026 (ending March 2026) amounted to ¥9,153 million, with the new Chubu plant enabling expanded production capacity and improved logistics efficiency. The company has built a multi-layered production and procurement system that also includes a manufacturing outsourcing agreement with Furano Agricultural Cooperative.
Based on a business and capital alliance concluded in 2011, Nissin Foods Holdings holds 45.1% of the company's issued shares. The two companies collaborate across all areas including product development, marketing, materials procurement, production, logistics, overseas business, and personnel exchange, establishing a framework that leverages the know-how and scale advantages of a major food group.
ENVALITH's Perspective
Performance Trend
Revenue expanded roughly twofold over four years, from ¥30,395 million in FY2022 to ¥61,156 million in FY2026, achieving five consecutive years of revenue growth. However, the growth rate has clearly decelerated: 46.7% in FY2023 → 23.0% in FY2024 → 8.3% in FY2025 → 3.0% in FY2026. Operating profit turned to a decline in FY2026, falling 3.7% year on year to ¥3,868 million, with the operating margin dropping from 6.8% to 6.3%. External factors—increased manufacturing costs due to poor potato harvests in Hokkaido, higher raw material prices, and wage-increase pressure—squeezed profits. Net income narrowly stayed positive at ¥2,594 million (up 0.2% year on year). For FY2027 (ending March 2027), the company forecasts revenue of ¥65,400 million (up 6.9% year on year) and operating profit of ¥3,900 million (up 0.8%), anticipating a profit recovery driven by the full-scale operation of the Chubu plant and price revisions.
Growth Strategy
A three-pronged strategy combining domestic expansion of high-value-added brands, multi-country overseas expansion, and utilization of the Chubu Plant
Promoting market entrenchment through continuous renewal and active promotion of high-value-added brands such as "Koikeya Pride Potato" and "Pure Potato." In response to rising raw material and labor costs, price revisions are being implemented sequentially in line with market trends to secure profitability. Domestic sales grew 3.0% year on year in FY2026 (ended March 2026).
Maximizing use of the "Koikeya Chubu Plant" in Kaizu City, Gifu Prefecture, which began operations in December 2025, to expand production capacity, improve logistics efficiency, and reduce manufacturing costs. As of the end of FY2026 (ended March 2026), net buildings and structures had expanded to ¥13,265 million, and cost reduction effects are expected to emerge as the utilization rate improves going forward.
Promoting channel expansion and profit improvement measures at bases in Taiwan, Vietnam, Thailand, and the United States. Continuing to expand distribution and the number of countries in which the global brand "Karamucho" is offered. Overseas segment profit sharply improved to ¥649 million (up 12.6% year on year) in FY2026 (ended March 2026). Also promoting an increase in the sales mix of high-margin products using corn and wheat as raw materials.
The local subsidiary KOIKEYA AMERICA INC. was established in June 2025, and the business scheme was overhauled and full-scale operations began in October of the same year. The new brand "SATISFRY" was launched in November and is being actively rolled out. The policy for FY2027 (ending March 2027) is to focus on market penetration of the brand, including channel expansion.
