Business Details
The domestic snack foods business operated by Koikeya Co., Ltd. as an independent management unit. In addition to its five existing production sites—the Kanto Plant, Kanto No. 2 Plant, Kanto No. 3 Plant, Kyoto Plant, and Kyushu Aso Plant—the company is transitioning to a six-site production structure with the addition of the "Koikeya Chubu Plant" in Kaizu City, Gifu Prefecture, which commenced operations in December 2025. The segment operates on two pillars: high-value-added brands centered on the flagship brand "Koikeya Pride Potato," and long-selling brands such as "Scorn" and "Karamucho." Major sales customers are Marubeni Corporation (21.0% of net sales) and Mitsubishi Corporation (13.3% of net sales). This is the core segment, accounting for approximately 90% of consolidated net sales.
Recent Overview
Sales rose 3.0% year on year, but segment profit fell 2.6% due to poor potato harvests and cost increases.
Domestic net sales for FY2026 (ending March 2026) increased to ¥54,733 million (up 3.0% year on year), but unexpected deterioration in potato yields due to summer temperature increases and poor Hokkaido potato harvests pushed up manufacturing costs, forcing a significant revision of product initiatives and sales plans in the second half of the fiscal year. Combined with continued increases in raw material and labor costs, segment profit was limited to ¥3,439 million (down 2.6% year on year). Meanwhile, the company actively pursued capital investment to expand production capacity and improve logistics efficiency, including the construction and launch of the new Chubu Plant in Kaizu City, Gifu Prefecture.
Key Products
Growth Drivers
- Sales expansion through continued promotion of high-value-added brands centered on "Koikeya Pride Potato" and the launch of new products
- Demand stimulation through the major renewal of "Pure Potato" and highly newsworthy promotions
- Growth of long-selling corn brands such as Scorn, Don Tacos, and Polinky
- Expanded production capacity and cost reduction through improved logistics efficiency by maximizing use of the Chubu Plant (Kaizu City, Gifu Prefecture), which began operations in December 2025
- Appropriate pass-through of cost increases and profit assurance through sequential price revisions reflecting market trends
Risks
- Significant increases in manufacturing costs due to poor potato yields caused by poor Hokkaido potato harvests and climate change
- Profit pressure from continued increases in raw material costs, logistics costs, and labor costs
- Long-term contraction of the domestic snack market due to the declining birthrate and aging population
- Risk of sales concentration in major customers (Marubeni and Mitsubishi Corporation), which together account for approximately 34% of net sales
- Risk of consumer attrition from additional price revisions if cost increases cannot be fully absorbed
- Expansion of fixed cost burden due to increased depreciation and lease obligations associated with the new Chubu Plant
