Konishi Koi Farm is one of Japan’s most historic and globally recognized breeders, located in Hiroshima and founded in the early 20th century. Established by Kakuichi Konishi and later expanded with a main shop in Misasa in 1963, the farm has evolved into a powerhouse known for producing some of the largest koi in the world. Today, it is led by third-generation owner Joji Konishi, who continues the family legacy with a focus on size, strength, and distinctive bloodlines.
Konishi is widely respected not only for its history but also for redefining expectations around jumbo koi. The farm has built its name on developing fish that combine impressive scale with friendly temperament and long-term durability.
THE ORIGINAL KARASHIGOI PIONEER
Konishi Koi Farm is credited with developing the Karashigoi variety in 1997, a breakthrough that changed the koi industry. Karashigoi koi are known for their massive growth potential, often exceeding 120 centimeters under proper conditions. These fish are admired for their thick frames, smooth lines, and strong, uniform coloration.
Beyond their size, Karashigoi are valued for their calm and friendly nature, making them popular with both collectors and hobbyists. Konishi’s Karashigoi remain the gold standard for the variety, consistently drawing attention at major shows and among international buyers.
JUMBO VARIETIES WITH GLOBAL RECOGNITION
While Karashigoi remains the farm’s signature achievement, Konishi also produces high-quality Kujaku, Ochiba and Shusui. These varieties are bred with the same emphasis on body mass, growth potential, and pattern stability.
Konishi koi have achieved top honors at prestigious events including the All Japan Koi Show. The farm’s ability to produce massive yet balanced fish has positioned it as a destination breeder for collectors seeking both size and show-level refinement.
LARGE-SCALE PRODUCTION WITH TRADITIONAL METHODS
Konishi Koi Farm operates an expansive facility that includes 80 to 100 rearing ponds along with more than 40 outdoor mud ponds. Despite its size, the farm maintains traditional, hands-on methods throughout its operations. This manual approach supports careful selection, disciplined culling, and close monitoring of each stage of development.
Multiple greenhouses house tategoi, future champion specimens carefully selected for growth and competitive potential. This blend of scale and selectivity allows Konishi to consistently produce koi that stand out in both private ponds and competitive arenas.
A GLOBAL NAME IN JUMBO KOI
Konishi’s influence extends far beyond Japan. With an established international presence and dedicated export channels, including Konishi Europe, the farm serves collectors worldwide. Its reputation for producing massive, high-quality koi has made it a major stop for enthusiasts traveling to Japan in search of elite specimens.
The combination of historic legacy, innovative breeding, and consistent jumbo results has secured Konishi Koi Farm’s place among the most respected names in the industry.
