MARUSAKA KOI FARM: LEADERS IN METALLIC VARIETIES

This Breeder Specializes in: Kujaku, and Hariwake.  

Marusaka Koi Farm has earned a strong reputation in Japan and internationally for breeding koi with high-impact metallic finishes and clean, refined patterns. Located in Niigata Prefecture — the birthplace of Nishikigoi — Marusaka is a family-run farm known for consistent results, bold color, and fish that shine in any pond.

Established in the 1960s, the farm is now operated by the second generation of the Marusaka family. Over the decades, they've stayed focused on producing koi that carry both visual presence and long-term pattern stability. While other farms concentrate heavily on Gosanke, Marusaka has carved out a name by excelling in metallic and Doitsu varieties.

Their koi are easily recognizable for their lustrous sheen, balanced patterns, and bright coloration. These are fish that demand attention, whether they’re swimming in a backyard pond or preparing for a show tank.

KNOWN FOR KUJAKU, HARIWAKE, AND YAMATO NISHIKI

Marusaka’s standout fish are Kujaku — a metallic koi with a white base, red or orange markings, and a reticulated black netting pattern that adds dimension. Their Kujaku are known for vibrant contrast and strong body confirmation, making them a popular choice for both beginners and advanced collectors.

In addition to Kujaku, the farm produces high-grade Hariwake with clean metallic white bodies and bright yellow or orange markings. Marusaka Hariwake are prized for their simplicity, shine, and symmetry.

Yamato Nishiki is another specialty. This variety blends the Sanke pattern with a metallic finish, creating koi that look both traditional and modern. Across all types, Marusaka’s koi carry a crisp, bold look made to last.

A FOCUSED FARM WITH RELIABLE RESULTS

Marusaka Koi Farm isn’t one of the largest in Niigata, but what it does, it does exceptionally well. Their breeding program is targeted and purposeful, focusing on koi that show reliable growth, color retention, and clean lines over time.

The farm raises koi in carefully managed mud ponds that naturally bring out their metallic luster and body shape. Breeding pairs are selected for both visual appeal and stability — making sure each generation holds strong potential.

The result is koi with consistent patterns, refined finishes, and balanced structure. Whether you’re drawn to flashy colors or metallic elegance, Marusaka koi bring visual clarity that holds up as the fish mature.
