01

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
02

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
03

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.

04

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.
