Breeders Specializing in Hajiro Koi Fish: 

Aokiya

Hajiro koi are a refined and minimalist variety that stands out through bold contrast and elegant simplicity. Characterized by a jet-black body sumiand pure white fin tips shiroji, this variety brings a quiet power to any pond layout. The stark contrast between body and fin edges creates a sharp, dignified look that koi collectors admire for its clean visual structure.

Hajiro koi differ from other varieties as they pay extra attention to form, contrast and finish. The deep sumi/ base is striking and gives an impression of strength alongside adding elegance that is achieved through subtle white edging on the pectoral and tail. Due to the coloring hues, they go well with vividly colored koi. Hajiro serves as the strong visual anchor within mixed collections, as their dark hues add balance and contrast to any pond.

At Fitz’s Fish Ponds, our Hajiro koi are sourced exclusively from Aokiya, an elite breeder known for producing high-contrast koi with flawless black skin and bright white fin highlights. Each fish is carefully hand selected for symmetry, clarity of sumi, and balanced fin contrast. If you're looking to add a sleek, powerful, and understated koi to your pond, our Hajiro collection brings sophistication in its purest form.

HAJIRO KOI FISH FAQS: SIZE, CARE, FEEDING, AND BUYING GUIDE

What is a Hajiro koi? Understanding this high-contrast koi.

+

A Hajiro koi is a black koi (sumi base) with pure white edges on its pectoral and tail fins. It’s a simple yet striking variety that emphasizes contrast and symmetry.

What makes Hajiro koi visually unique?

+

Their clean, uninterrupted black body color combined with crisp white fin tips gives them a commanding and minimalist appearance. It's a koi that makes an impact without busy patterns.

How big do Hajiro koi typically grow?

+

With good care, Hajiro koi can reach 26–32 inches. Their bold coloration tends to intensify as they mature, especially when raised in clean, stable water.

Are Hajiro koi a good option for beginners?

+

Yes, Hajiro are hardy, easy to care for, and not prone to color instability. Their simplicity and low-maintenance pattern make them an ideal choice for any koi keeper.

Do Hajiro koi get along with other koi?

+

Absolutely. They are calm and sociable and work well in ponds with multiple koi varieties, especially alongside brighter or patterned fish where their contrast stands out.

What should I feed my Hajiro koi?

+

A high-quality pellet formulated for color and immune health is ideal. While they don’t rely on color-enhancing food like some varieties, nutrition supports deep, healthy sumi.

How do I care for Hajiro koi during winter?

+

Like other koi, these fish become dormant in the winter. You’ll want ample depth in your pond, a pond heater or a de-icer to ensure longevity.

Can I keep Hajiro koi in a small pond?

+

They’ll thrive best in medium to large ponds where their size and movement can be appreciated. Open space helps their clean lines and contrast shine.

Are Hajiro koi rare? What makes them desirable?

While not rare, Hajiro with even black coloration and bright, clean fin tips, especially from breeders like Aokiya, are highly sought after. Their timeless style adds grounding contrast to any pond design.

Why should I buy Hajiro koi from Fitz’s Fish Ponds?
