Koi show calendar

By the koi.wiki editorial team · Updated

Key facts: Koi shows are held on recurring annual or biennial schedules set by national and regional organizations such as the All Japan Nishikigoi Promotion Association (JNPA, 全日本錦鯉振興会), Zen Nippon Airinkai (ZNA), and various national koi clubs, with dates, cities and venues published by each organizing body.[1][2]
Koi show dates are set independently by the organization running each event, so there is no single global calendar; keepers typically consult the announcements of the relevant national or regional body such as the All Japan Nishikigoi Promotion Association (JNPA), Zen Nippon Airinkai (ZNA), or a country's koi association for current dates.[1][2]In Japan, major JNPA events follow a consistent seasonal pattern: the All Japan Combined Nishikigoi Show is held in January at the Tokyo Ryutsu Center, the All Japan Young Koi Show in March at Himeji Castle's Otemae Park, and the International Junior Koi Show in April at the Ojiya City Gymnasium Community Plaza in Niigata.[1] ZNA also lists dozens of chapter-level shows across Japanese prefectures, many recurring in spring or autumn, as well as its flagship ZNA International Koi Show.[2][3]Outside Japan, national associations and clubs in the United States, United Kingdom and Europe publish their own yearly lists, generally concentrated in spring through early autumn.[4][5]

How to read the calendar

The table below compiles show dates, cities and venues as published by the organizing bodies cited for each row. Edition numbers (such as “57th”) and dates reflect each organization's own count and may change if a show is postponed or renamed; readers should verify current details directly with the organizer before attending.[1][2][4]Status is marked “upcoming” where the source lists a future date, or “recent/past” where the source marks an edition as ended.[2]

Japan

JNPA's three flagship national shows recur annually: the All Japan Combined Nishikigoi Show in Tokyo (January), the All Japan Young Koi Show in Himeji (March), and the International Junior Koi Show in Ojiya, Niigata (April).[1] For example, the 56th All Japan Combined Nishikigoi Show was held January 24–25, 2026, and the 57th is scheduled for January 30–31, 2027, both at the Tokyo Ryutsu Center.[1]ZNA separately organizes an International Koi Show; its 62nd edition is scheduled for November 13–15, 2026, at Tokiwa Park in Ube City, Yamaguchi Prefecture, with free admission and a published schedule including judging, an opening ceremony, a show banquet, and public viewing hours.[3]ZNA also lists a large number of prefectural chapter shows across Japan, such as the Shiga chapter's 51st show on November 8, 2026 and 33rd Young Koi Show on April 26, 2026, and the Kyoto chapter's 55th show on December 13, 2026; many chapters' dates were listed as not yet finalized at the time of publication.[2]A related industry event, the 2nd World Nishikigoi Summit, is scheduled for November 8, 2026 at the Toki Messe International Conference Hall in Niigata City, aimed at koi-industry representatives from multiple countries.[6]

United States

The American Koi Judges Association (AKJA) publishes an annual list of US shows. For 2026 this includes events such as the Central Florida Koi & Goldfish Show in Orlando (March 6–8), the Koi Club of San Diego show at the Del Mar Fairgrounds (March 7–8), the ZNA SoCal Koi Show in Gardena, California (March 21–22), the All American Koi Show in Las Vegas (March 27–29), the Music City Koi Show in Nashville (April 10–12), the Dallas Koi Show (May 16–17), the Atlanta Koi Club Annual Show (June 12–14), and several September shows including the Rocky Mountain Koi Show and Aquatic Expo in Castle Rock, Colorado, the Miami Koi Show, and the Fresno Koi Show in California.[4]According to its own 2026 exhibitor registration packet, the ZNA SoCal Koi Show celebrated its 50th annual edition on March 20–22, 2026 at the Gardena Civic Center Complex, co-sponsored by the City of Gardena, describing itself as the longest-running koi show outside Japan and hosting the ZNA America Western District show that year.[7]Zen Nippon Airinkai America also lists international chapter shows, such as the 2025 ZNA Taiwan District Koi Show held December 6–7, 2025 in Hsinchu Taoyuan City, Taiwan.[8]

United Kingdom and Europe

Koi Judges UK, formerly part of the British Koi Keepers Society's judging committee, lists UK and continental European shows for 2026 and early 2027 dates.[5] For 2026 these include the Belgian ZNA Koi Show at Expo Waregem (April 18–19), the European Koi Show at Het Hulsbeek, Oldenzaal, Netherlands (May 30–31), the National Koi Show at the Heart of England Conference & Event Centre, Fillongley (June 27–28), the Scottish Koi Show (July 25–26), the ZNA Holland Koi Show at Bloemenpark Appeltern (August 15–16), and the Great British Koi Show at Newark Showground (August 29–30).[5]The Great British Koi Show's 2026 dates are independently confirmed by the Midland Koi Association as Saturday, August 29 and Sunday, August 30, 2026 at Newark Showground, Coddington, Newark.[9]For 2027, Koi Judges UK lists the Belgian ZNA Koi Show (May 1–2), the European Koi Show (May 29–30), the UK National Koi Show (May 29–30), the Scottish Koi Show (July 24–25), the ZNA Holland Koi Show (August 21–22), and the All England Koi Show (September 25–26).[5]The National Koi Show Association publishes its own constitution and exhibitor terms and conditions for the National Koi Show, dated 2026.[10]The Holland Koi Show organizers state on their own site that the 2026 Young Holland Koi Show is held Monday, May 25 at Veldhoven Koi Farm, and the main Holland Koi Show runs August 15–16, 2026, describing it as the largest koi show in the world.[11]

Other regions

According to Minurphy, a South African show-tarpaulin manufacturer and show sponsor, the 2026 SA National Koi Show was held August 1–2 at Crusaders Sports Club in Durban North, hosted by the SAKKS KZN Chapter and judged under ZNA standards; the source states the national show alternates annually between Johannesburg and Durban.[12]

Why dates and venues vary year to year

Several sources show that even long-running shows can change venue or host club from year to year; for instance the South African national show is reported to alternate cities, and the Holland Koi Show's Young show venue and date have changed between editions.[12][11] Chapter-level ZNA shows in Japan frequently list dates as “to be determined” well into the preceding year, and some chapters' listings show no scheduled date at all, reflecting local organizing capacity rather than a fixed annual slot.[2]
