AOKIYA KOI FARM: A RISING NAME IN JAPAN'S KOI WORLD

Located in Ojiya City, in the heart of Niigata Prefecture, Aokiya Koi Farm has quietly become one of the standout names in modern koi breeding. Founded by Tetsuya Aoki, the farm is built on a balance of hands-on tradition and a fearless approach to variety development. While many breeders stick closely to Gosanke, Aokiya focuses on rare, eye-catching varieties that are making waves in both Japanese and international markets.

Aoki-san is deeply involved in every aspect of the farm, from breeding pair selection to harvest. His koi are known for sharp color contrast, striking patterns, and strong conformation — qualities that continue to attract attention from collectors and dealers worldwide. As demand for more unique koi grows, Aokiya’s bold and artistic fish are finding their way into top-tier collections across Europe, Southeast Asia, and the United States.

KNOWN FOR GOSHIKI, DOITSU SHOWA, AND VARIETIES THAT STAND OUT

Aokiya Koi Farm is best known for Goshiki — a variety that blends metallic blue and deep black base tones with vibrant red markings. Their Goshiki are easy to spot thanks to their consistent pattern and intense color. These fish often develop beautifully as they age, making them a wise choice for hobbyists who enjoy watching koi evolve.

In addition to Goshiki, Aokiya also produces impressive Doitsu Showa, a scale-less version of Showa with a cleaner, sharper look that stands out in any pond. Other standout varieties include Doitsu Sanke, Kujaku, and Beni Kikokuryu — all bred with the same focus on appearance and character.

Instead of chasing the same look year after year, Aoki-san is constantly refining his stock and experimenting with lines that can offer something different. If you’re looking for koi that feel bold, original, and full of visual interest, Aokiya provides a refreshing change of pace from more traditional farms.

KOI FROM A BREEDER WHO WORKS WITH PURPOSE

Tetsuya Aoki’s approach is grounded, thoughtful, and personal. His farm isn’t a massive operation — it’s a focused, high-effort setup where every koi is raised with close attention. Breeding is done in small, well-managed groups, and development is carefully tracked across each season.

Aokiya’s mud ponds are managed for slow, even growth, helping koi develop deeper color and fuller shape without being rushed. What’s more, Aoki-san’s breeding selections are based on a long-term vision — one that emphasizes balance, clarity, and body strength across generations. That kind of focus is rare, and it shows in the fish he produces year after year.
