SHOP KOI FISH FROM SHINTARO KOI FARM – ELITE BLOODLINES, BOLD COLOR, UNMATCHED BEAUTY

Shintaro Koi Farm is located in the heart of Yamakoshi, Niigata, and has become one of the leading names in Japanese koi breeding, particularly known for its dynamic Showa. Operated by Toru Saito, the farm has gained a loyal following for producing koi that have strong body presence, bold sumi markings and a striking overall look. Shintaro’s approach to koi breeding is one of patience, deep understanding of bloodlines, and a sharp eye for koi that turn heads in ponds and shows alike.

Showa is the specialty here. Shintaro koi are built for visual impact, with rich black sumi that cuts cleanly across pure white and deep red skin. The placement of color is never accidental. Every koi is bred with long-term development in mind, often becoming more impressive as they mature. These are the kind of fish that grow into their full potential, making them favorites among collectors who value koi that age with style.

In addition to Showa, Shintaro Koi Farm also produces a selection of other varieties including Ginrin Showa and some Doitsu types that showcase sharp, high-contrast patterns. The farm’s focus is small-scale, which allows for meticulous breeding and hands-on care through every stage of a koi’s development. The result is koi with strong appeal and pattern layouts that stand out from the crowd.
