Omosako Koi Farm is Japan's number one Shiro Utsuri breeder, and frankly, nobody else can compete when it comes to the high-class examples. We have been buying here for some 20 years now. In recent years, Omosako have also started breeding Kujaku and Goshiki with good success. The farm has also seen considerable expansion over the last 7 or 8 years as well, so that they can produce higher numbers of higher level Koi.
