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

Aokiya Koi Farm, often referred to simply as AO Aokiya, is a world-renowned breeder located in Katakai, Ojiya City, Niigata Prefecture, Japan. Founded in 1972 by Haruo Aoki, the farm quickly gained recognition for its innovative approach to koi breeding and its ability to develop striking metallic and Doitsu varieties with exceptional clarity and contrast. Today, the farm is managed by Motoyoshi Aoki, who continues to expand on that legacy while maintaining the disciplined standards that define Aokiya koi.

Set across a substantial facility of approximately 20,000 square meters, Aokiya operates in the heart of Niigata’s koi country, where pure mountain water and seasonal climate shifts support healthy, resilient koi development. Over the decades, the farm has become synonymous with creativity, precision, and clean pattern work.

MASTERS OF METALLIC AND DOITSU VARIETIES

Aokiya Koi Farm is widely regarded as a master of metallic koi and Doitsu varieties. The farm has earned global respect for producing exceptionally clean-skinned fish with bold, vibrant color and sharply defined pattern edges. Among its most celebrated creations is the Kikokuryu, a dramatic black-and-white metallic Doitsu koi, along with the Beni Kikokuryu, which incorporates rich red accents into the contrast.

Beyond these signature creations, Aokiya produces Goshiki, Doitsu Kohaku, Doitsu Sanke, and Kujaku. Their Goshiki in particular are considered among the most consistent and refined in the world, known for strong underlying sumi and vibrant overlay patterns that develop beautifully with age.

A BREEDING PHILOSOPHY ROOTED IN INNOVATION

Unlike farms that focus exclusively on traditional Gosanke, Aokiya places strong emphasis on developing new and distinctive varieties. This forward-thinking approach has made the farm a leader in creative koi breeding while still preserving structural integrity and long-term growth potential.

The farm employs a rigorous multi-stage culling process designed to prioritize skin quality and sumi development from an early stage. Young koi are evaluated carefully to ensure that contrast remains sharp and stable as they mature. This disciplined selection contributes to the high consistency that collectors associate with the Aokiya name.

LARGE-SCALE PRODUCTION WITH HIGH DEMAND

Operating across its expansive facility, Aokiya produces a significant number of koi annually, yet demand often exceeds supply. Tosai and nisai from the farm frequently sell out quickly due to strong international interest. The balance of volume and strict quality control allows Aokiya to maintain both availability and high standards.

Collectors are drawn to Aokiya koi for their intense coloration, crisp pattern separation, and strong body conformation. The farm’s metallic varieties in particular stand out in ponds due to their reflective sheen and bold contrast.
