Our team has over 20 years of experience in aquaculture and fish nutrition. This deep knowledge has helped us establish strong partnerships with elite Japanese breeders, including Dainichi, Sakai, Momotaro, and more. Through our associates in Japan, we maintain preferred buying status and ensure each Koi meets the highest health and aesthetic standards.
We’re more than a retailer — we actively support the global Koi community. Our fish have proudly participated in prestigious Japanese Koi shows, including the renowned All Japan Koi Show, with 24 Azukari Koi currently in competition.
Grand Koi was conceived by a group of koi enthusiasts and aquaculture experts from the US, Japan, and the Middle East. With decades of experience in fish farming, feed manufacturing, and water quality management, the founders envisioned a premium platform that could bring world-class Japanese koi to North America. Their shared love for koi culture, craftsmanship, and aesthetics became the driving force behind this ambitious venture.

After extensive research, the team selected a site in rural Texas for its ideal climate and water quality. Construction began on a state-of-the-art bio-secure facility, designed in collaboration with Japanese architects to replicate the natural mud ponds and filtration systems of Niigata. This facility was engineered to be the premier koi breeding and quarantine center in North America.
