Separate the business roles
A farm may breed and sell its own koi, while a dealer may offer stock from many breeders. An exporter may hold koi from several sources and coordinate certificates and flights. Some businesses combine these roles, but a directory listing alone does not prove that every service is currently available.
- Breeder for a specific bloodline or farm
- Dealer for comparison across breeders
- Exporter or agent for an international shipment
Search by speciality and current stock
A breeder's reputation for Kohaku, Showa, Goshiki or another variety is a useful starting point. Current availability is separate. Send the variety, size, age, budget, destination and timing you need.
- Variety and pattern preference
- Budget per koi or total budget
- Visit, domestic delivery or export
- Destination country and preferred timing
Use location to plan a visit
Ojiya, Yamakoshi and the wider Nagaoka area contain many koi businesses, but farms are spread across working rural sites. Never assume walk-in access. Confirm the meeting point, language needs, biosecurity rules and what stock can be viewed on the day.
Treat public listings as a starting point
Association and export-facility lists help identify businesses and roles. Koi Atlas combines those signals in one directory, then confirms sales, visits or export conditions after receiving a specific request.
