It’s summertime, meaning, breeding season for the Japanese koi breeders. Super busy times and long days. But in Autumn we can see all the good results.
Breeding koi is a professional job and a challenge every time again.

We, at JKS, guide the professional koi dealers around the Japanese breeders, or select koi on your demand, or offer them through our online auction and our website.
We take care of logistics and ship worldwide. We have an unbeatable service and experience.

We speak your language and have professionals in our team with many years of experience. Care to join us? Get in touch with us, you will be surprised of what we can do for you.

Summertime is not only the time for koi breeding and selections. But also to do maintenance on the koi houses, and with temperatures well over 30 degrees it’s a seriously hard job.

Summer is the time of sembetsu for the breeders in Japan. It’s the time of year every breeder is starting to dream of what the future will bring. Will that little koi of just a few centimeters grow out to become a future champion? So many things are still unsure and so many things still can go wrong, but there is nothing wrong with dreaming!
