Purchased from the No1s auction, so should come with a breeders certificate. Famous for there sanke and asagi, of later they are producing showa and kohaku that sizes are similar to the farms in the South . This koi you can see has much more improved kiwa and sashi than the previous Oya Kohaku, and i think a more interesting pattern and a tail stop. A little more expensive but a great koi for the money.
