Koda Koi Farm, founded and led by Masato Hoshino, is one of Niigata’s most respected koi farms. Nestled in Kawaguchi, near Nagaoka City, the farm spans over 50,000 m² of rearing grounds and has earned an international reputation for producing koi of exceptional beauty, quality, and strength.

Since its establishment, Koda Koi Farm has been dedicated to blending traditional Japanese koi breeding methods with careful innovation. The farm’s philosophy is simple:

• Breed koi that embody both powerful body conformation and refined patterning
• Raise koi in harmony with the natural cycles of Niigata’s mountains, ponds, and seasons
• Share the elegance of Nishikigoi with collectors and enthusiasts worldwide

Each koi is nurtured with passion and expertise, from tosai to jumbo koi, reflecting decades of selective breeding.

Koda Koi Farm is particularly renowned for:

• Goshiki & Ginrin Goshiki – celebrated for their deep beni and shimmering reticulated patterns
• Ginrin Showa – dynamic tri-coloured koi with vibrant metallic sparkle
• Showa Sanshoku and other high-quality Gosanke
• A strong range of supporting varieties, each carefully developed to showcase distinct beauty

The farm’s Goshiki, in particular, are recognised internationally for their richness of colour and intensity, making them highly sought after in competitions and private collections.

• Over 50,000 m² of rearing grounds in Kawaguchi, Niigata
