Producing Regions, Quarantine & Export Gates
Why a region's fish can or cannot travel — export qualification as a fact of production geography.
| China trade | Suspended about a year, reopened October 2024; six farms in Niigata, Fukuoka and Hiroshima qualified |
|---|---|
| System | Export requires quarantine and health certification through official channels; qualification is farm-by-farm |
| Lesson | Export gates open and close with disease and diplomacy — always re-check official sources |
The China reopening of October 2024 is the clearest recent lesson in how koi geography works: a market closed for about a year, then reopened to named, qualified farms in three prefectures. Production prestige and export permission are related but not identical — permission is an official, farm-level status.
The same principle runs through this guide's import pages. Conditions depend on the destination country, the farm's status and current disease findings, and they change. Nothing on this site certifies that any specific fish or farm can be exported; the official confirmation routes are listed on the import guide page.
For region pages, the takeaway is modest and factual: when you read that a region exports, read it as 'qualified farms in this region export under current rules', with a check date attached.
