Young Koi Shows & Other Major Events

Wakagoi and national breeder shows — where tomorrow's champions are first seen.

Below the All Japan peak sits a tier of major events with distinct jobs. Young koi shows (wakagoi) judge fish in the small and middle classes, where breeders test bloodlines early. National and international shows run by the hobby's federations and breeder associations give regions and younger fish their own championships.

Regional shows matter to travellers most: they are smaller, friendlier to a first visit, and often paired with sales and auctions run by organisers — this guide notes their existence and rhythm without listing commercial details.

Names, venues and dates are set by each organiser each year. Use this page to understand the tier each event occupies, then confirm the current edition officially before you travel.
