Pride & Passion

We at Toyoma Koi have been personally importing Nishikigoi from Japan for more than 35 years. Our Koi are hand-selected from breeders in Niigata Prefecture, where Koi breeding and collecting started over two centuries ago.

We have developed close personal relationships with breeders that few Western dealers possess, giving us — and our customers — access to Koi of the highest quality during our time in Japan. We are proud of every fish we transport back from Japan, and we handle them with great care and attention.
