Shintaro Koi Farm is located in the historic Yamakoshi region of Niigata, Japan, an area widely regarded as the spiritual home of Nishikigoi. Operated by Masaru Saito, Shintaro has grown into one of the most respected names in modern koi breeding, earning global recognition for producing powerful, visually striking koi with exceptional presence.
The farm has become a must-visit destination for serious koi enthusiasts traveling to Japan. Its reputation is built on patience, a deep understanding of bloodlines, and an uncompromising eye for koi that command attention both in ponds and on the show circuit.
STRONG BLOODLINES AND JUMBO POTENTIAL
Shintaro Koi Farm works extensively with Matsunosuke bloodlines, known for their robust growth and championship-level structure. This foundation allows the farm to consistently produce koi with powerful frames, broad shoulders, and smooth body lines. It is not uncommon for Shintaro koi to reach impressive sizes early, with some three-year-old fish exceeding 70 centimeters under proper conditions.
The farm operates more than 60 mud ponds across the mountainous Yamakoshi and Kawaguchi areas, providing ideal environments for summer growth. These natural conditions play a key role in developing skin quality, body mass, and overall vitality, contributing to the jumbo potential Shintaro koi are known for.
ADDITIONAL VARIETIES WITH THE SAME REFINED APPROACH
While Showa remains the flagship variety, Shintaro Koi Farm also produces Sanke and Kohaku that reflect the same disciplined breeding philosophy. These koi display clean skin, balanced patterns, and strong structures that hold up as they mature.
In addition, the farm breeds select Ginrin Showa and Doitsu types that offer sharp contrast and bold visual appeal. Production remains intentionally focused rather than high volume, allowing hands-on care throughout every stage of development. This approach ensures that each koi leaving the farm reflects Shintaro’s standards for quality and presence.
A GLOBAL REPUTATION FOR SHOW-QUALITY KOI
Shintaro koi have achieved major success on the international stage, earning Grand Champion titles in regions including the United Kingdom, Europe, Thailand, and the United States. These results have solidified the farm’s reputation as a producer of koi capable of competing at the highest levels worldwide.
The farm’s annual harvest is considered a major event within the koi industry, drawing collectors and dealers eager to secure top-tier fish. Masaru Saito’s sons and farm staff play an active role in breeding, selection, and harvest, reinforcing the family-driven nature of the operation.
