Mukashi Ogon koi boast a warm, antique-gold tone paired with a dense, metallic luster that causes their scales to glimmer as if polished by decades of water. The word mukashi translates as “old style,” nodding to their status as one of the first metallic strains ever bred in Japan. Compared to the brighter Yamabuki Ogon, their bronze-gold garment presents a more grounded, earth-toned look without sacrificing elegance.

At Fitz’s Fish Ponds, we source from top Japanese breeders including Marudo, Marusei, Maruhiro, and Sakai, names known for producing koi with exceptional form and consistency. Each fish is carefully inspected, and we only choose those with even coloration and a strong, well-balanced body. These koi are perfect for collectors who want a centerpiece that’s both striking and understated, commanding attention without overwhelming the pond. Browse our
