Yamamatsu Koi Farm otherwise known as Matsunosuke, won the championship at the All Japan Combined Nishikigoi Show in 1955 for his Taisho Sanshoku (Sanke). Sanke became the trademark of Matsunosuke. Currently, many breeders use Matsunosuke’s Koi as Oyagoi, and a Matsunosuke genealogy brand was established.
