igarashi kazuto has to be on anyones top ten, His indoor fish house is home to some of the finest go-sanke. prices are high, but you have to pay for quality. Can I just say great thread and a lot of fun, however we in England go through fads with breeders it used to be sakai brothers, then hiroshima sakai and now everyone is into Momotaro. They are all great breeders and will continue to do so, however everyone forgets the smaller breeders especially in the north.About 10 % of all breeders production is top quality the finest koi. Its just that places like Sakai hiroshima are about the same size as a Niigata village housing about 7 koi breeders.So the massive volume of koi cant be bread, leaving a small amount of koi to be top class. And when you visit Hiroshima sakai your see hundreds of high class koi, just think if a breeder in the niigata area such as Kazuto could have the same facilities and space
