How much do koi cost?
Key facts: Koi prices range from a few hundred yen for young, basic fish to tens of millions of yen for show-quality champions, with the record auction sale reaching 230 million yen (about £1.4 million).[1][2]
According to the All Japan Nishikigoi Promotion Association (JNPA), nishikigoi (錦鯉) are available at prices as low as 500 yen or 1,000 yen, making them accessible to beginning hobbyists, while exceptional show koi have sold for tens of millions of yen at auction.[1] In the United States, the dealer Kodama Koi Farm states that koi prices range from about $10 for a five-inch juvenile to over $50,000 for champion-level quality.[3] Price is driven by a combination of bloodline, body conformation, pattern quality, size, age, and variety.[3][1]Typical price ranges
The JNPA notes that koi priced in the millions of yen are exceptional; most koi offered for sale by its member shops range from about a thousand to ten thousand yen, with some priced at less than a thousand yen.[4] The organization states the probability of a koi reaching a price in the millions of yen is less than 0.01%.[4]According to Kodama Koi Farm, an imported Japanese koi can be worth $100–$1,500 on average, while a champion-level koi can exceed $50,000.[3] The same source suggests beginners start with smaller, younger fish or mixed packs typically priced from $45 to $150 per koi.[3] A secondary account from a 2008 report on the Asian koi market quoted an industry expert estimating that a grand champion koi could fetch 10–15 million yen (roughly 95,000–143,000 US dollars at the time), with some historical sales during the 1980s boom reportedly reaching 50–100 million yen.[5]The record sale: S Legend
The highest publicly recorded price for a single koi involved a Kohaku (紅白) named S Legend, a nine-year-old, 101 cm female bred by Sakai Koi Farm in Hiroshima.[1][2] According to the JNPA, the fish sold at auction for 230 million yen.[1] Kodama Koi Farm and a Daily Mail report covering the October 2018 sale put the figure at 203 million yen, equivalent at the time to about $1.8 million or £1.4 million, roughly £1 million above the previous record.[3][2] The buyer was identified as a collector named Miss Yingying from Taiwan, who purchased the fish from breeder Kentaro Sakai after a bidding war at his Hiroshima farm.[2][3] The Daily Mail reported that she planned to let the koi compete again in the All Japan Koi Show, where there is no prize money but significant prestige.[2] Read more about this sale on the record koi prices and S Legend page.The same report noted that, by contrast, ordinary pond koi in the UK market could cost as little as £12.50, while larger koi with near-perfect coloring could sell for up to £2,000, with higher-quality examples reaching £20,000.[2]Historical prices
Historical records cited on Wikipedia indicate that koi prices have long varied with rarity. In 1900, a three-colored carp at Ritsurin Garden in Takamatsu, Kagawa Prefecture, was priced at over 1,000 yen, described as a high price for that era.[6] A 1910 magazine account noted that nishikigoi at a fish show in Fukagawa, Tokyo, sold for 100 to 150 yen per fish, described at the time as “extremely expensive.”[6]What drives the price
- Bloodline, body conformation, pattern quality, and rarity of variety are described by Kodama Koi Farm as the primary factors determining a koi's price.[3]Size correlates directly with cost, and larger fish generally cost more; a jumbo koi longer than 24 inches (61 cm) and weighing up to 40 pounds (18 kg) is described as highly sought after and priced at a premium.[3]Age affects price: older, larger fish such as nisai and sansai koi generally cost more than one-year-old tosai, though young koi with “great potential” (tategoi) may still be valuable.[3]Variety matters: Kodama Koi Farm states Kohaku, Sanke, and Showa are the most popular show varieties and usually the ones that win Grand Champion titles.[3] See the Kohaku, Taisho Sanshoku, and Showa Sanshoku pages for details.Origin affects cost: Kodama Koi Farm notes that domestic (non-Japanese-born) koi are generally lower cost than authentic Japanese-bred koi, reflecting differences in bloodline and breeding standards; see Japanese, domestic, Israeli and Chinese koi.[3]Grading into show-quality versus pond-quality categories also affects price, with show-quality koi possessing superior body conformation and pattern, according to Kodama Koi Farm.[3]
Additional costs beyond purchase price
Kodama Koi Farm notes that shipping costs for koi in the United States can range from about $99 to $330 or more per box, varying by location, and that international shipping depends on each country's import requirements, including health certificates.[3] See shipping, bagging and acclimation for more on this process. The same source states that ongoing koi food costs can run from about $50 to $200 or more per month depending on pond size and season, with additional costs for electricity, water treatments, filter media, and health supplements.[3] For comparison, the US Southern Regional Aquaculture Center notes that as prices of koi increase, the size of the potential buyer market decreases, so most commercial koi production occurs at the lower end of the price range.[7]Buying koi in Japan
The JNPA describes koi shops in Japan as falling into three categories: breeders, retailers, and breeder-retailers, some of which sell directly to hobbyists and others only wholesale to retail stores.[1] It recommends purchasing from retail stores affiliated with the association to help ensure quality and health standards, noting that online sales carry potential concerns such as disease transmission.[1] See breeders, dealers and importers for more on purchasing channels, and koi auctions for how high-value sales such as S Legend's are conducted.Common questions
What is the cheapest a koi can cost?
According to the JNPA, basic nishikigoi can be purchased for as little as 500 to 1,000 yen, making the hobby accessible to beginners.[1]
What is the most expensive koi ever sold?
Why are some koi so much more expensive than others?
Price depends chiefly on bloodline, body conformation, pattern quality, size, age, and rarity of variety, with show-quality fish from proven lineages commanding far higher prices than ordinary pond-quality koi.[3]
Are Japanese koi always more expensive than domestic koi?
According to Kodama Koi Farm, domestically bred (non-Japanese) koi generally cost less than authentic Japanese-bred koi, which reflects generations of selective breeding and strict culling standards.[3]
What other costs come with buying a koi besides its purchase price?
Buyers should budget for shipping, which Kodama Koi Farm estimates at roughly $99 to $330 or more per box in the US, plus ongoing monthly food costs of about $50 to $200 or more depending on pond size.[3]
