Taisho Sanshuko

Proper name of the variety usually called Sanke. Sanshoku means three colours. While breeding Kohaku, Koi with black pigments suddenly appeared. While the primary evaluation is still based on the Kohaku pattern, the variety was improved to have the added highlight of large, lacquer black Sumi patches that these Koi are known for today.
