Kōyō-zuke (紅葉漬), also written koyo-zuke or koyozuke, is a ready-to-eat fermented salmon specialty from the Abukuma River basin in northern Fukushima. It is cured with rice koji and salt, served in small portions, and sold chilled or frozen; regional producers trace the recipe to local tradition and still sell branded versions today.
Production is simple in concept: fillet and cut salmon, mix with rice koji and salt, allow curing and maturation, then package. Some modern products add mirin, seasonings, antioxidants, or ikura (salmon roe).
Storage and labeling vary by product—follow the label. Long-standing makers such as Fukushima Kōyō-zuke Co. registered a trademark in 1963 and report keeping an inherited ingredient ratio.
# What kōyō-zuke is
# Name and regional reading
The dish is tied to the Abukuma River basin, especially Yanagawa in Date City. Local accounts describe abundant salmon runs in the river during the Edo period and say salmon moved upriver in autumn, which is one explanation for the name kōyō (autumn foliage): either the fish were caught during leaf-change season or the finished product's reddish salmon and white koji visually echo autumn colors.
Producers and regional sources trace the recipe by local tradition to the Bunsei era (1818–1830). That date is a local tradition rather than a documented year. Modern commercial history is clearer: a family wholesaler that worked the area developed the product, established Fukushima Kōyō-zuke Co. in 1963, and registered a trademark to market the product beyond the local area.

Serving: small portions on hot rice, paired with sake, or added to ochazuke. Because it's strongly seasoned, it functions as an accent rather than a main course.
Storage: products are sold chilled or frozen depending on the manufacturer. Follow the product label for refrigeration and shelf-life instructions.
# Where to buy
Kōyō-zuke remains a regional specialty sold by local producers in and around Yanagawa and Date City. Long-established companies such as Fukushima Kōyō-zuke Co. still make and market it, and other local producers have their own variations. Labels will indicate ingredient choices (domestic salmon, sockeye, added ikura, etc.) and storage requirements.
