Shiro Utsuri is the reason to buy from Omosako. The farm has won Best in Variety for Shiro Utsuri at the All Japan Nishikigoi Show twelve years running, by its own count, and it is the bloodline other Shiro Utsuri breeders measure themselves against.
Ryuzo Omosako started the business in Kure, Hiroshima, in 1960 as a koi dealer, driving a truck with a water tank to Niigata and back to fetch fish. He built the farm at Tochihara in 1973. In 1978 he came across a Shiro Utsuri that changed his idea of what the variety could be, and from 1979 the farm set out to breed its own. The company incorporated in 1992. His sons Takayoshi, the current representative, and Takahiro run it today.
Kujaku is the second string and a strong one: an Omosako Kujaku took the jumbo division championship at the 2020 All Japan show. The farm also breeds Showa, Ginrin Shiro Utsuri, Ginrin Showa and Goshiki. It does not breed Kohaku or Sanke. If you want a Hiroshima Gosanke, look at another farm. If you want a Shiro Utsuri with the heavy, clean sumi the line is known for, this is the one.
