What is the Rarest Type of Koi?

Koi fish are famous for their bright colors, smooth movements, and unique beauty. While many koi types are admired for their stunning patterns, some are really rare because of their special features or how hard they are to find. From the shiny, metallic Gin Rin to the prized Kohaku with perfect markings, the world of rare koi fish is full of surprises.

Beyond common varieties lies a rare world of Nishikigoi, prized for their unique patterns, care requirements, and extraordinary value.

Rare Koi Collectors:  The Hunt for Exotic Koi Fish

 

For collectors, rare Nishikigoi are more than just fish—they are living art. Each tells a story through its colors, patterns, and movements, symbolizing perseverance, strength, and good fortune in Japanese culture.

Pursuing rare koi involves passion and dedication, from prestigious auctions showcasing world-class specimens to breeders refining koi genetics. Collectors often spend years seeking the perfect koi, finding unmatched joy in discovering exceptional specimens.

Understanding Rarity in Koi: Rare Varieties and Patterns Explained by Taro Kodama

From Taro Kodama: “Rarity holds several meanings for me, and it can be understood in the following ways:

 

Rare Koi Variety

 

Some koi varieties are considered rare because only a few breeders focus on them, often due to limited demand.

    • Bekko: A relatively less popular variety.
    • Golden Corn (Taniguchi), Yama Kagashi (Ikarashi), Sumi Sakura (Fukasawa Koi Farm), Kirin (Wada Koi Farm), and Pearl Ginrin (Sekiguchi): These varieties are challenging to breed successfully.
    • Beni Kikokuryu: Another example of a rare and difficult-to-breed variety.

Rare Koi Scale Pattern

 

Rarity isn’t always about show-quality patterns but about unique and uncommon ones.

    • A 5-step Kohaku pattern is rare, even though Kohaku itself is not a rare variety.
5-step Kohaku pattern refers to a specific type of marking with five distinct red markings (steps) on the fish’s body, typically along its back. These markings are usually located in a balanced way, starting from the head and moving down the body, each marking separated by white space. This type of pattern is highly valued in Koi judging because it creates a visually appealing and symmetrical appearance.
    • Common patterns include Tancho, 1-step, 2-step, and 3-step, but 4-step and especially 5-step patterns are seldom seen.”

Tancho, 1-step, 2-step, 3-step, 4-step, and 5-step refer to the number of distinct color markings (usually red or orange) on the fish’s body. These steps are a way to describe how the red markings are arranged, specifically on the white or light-colored body of the fish.

Maruten 5 Step Pattern : koi fish with a red crown on its head and red patterns on the rest of its body. It’s similar to a Tancho koi, but with more red on the body. .

What Defines a ‘Rare’ Koi Fish?

 

A rare koi fish is defined by unique characteristics such as uncommon patterns, vibrant colors, specific genetic traits, or exceptional quality that deviate from standard varieties. Rarity can also be influenced by lineage, limited availability, or winning features in koi competitions.

 

Koi fish are often celebrated as living works of art, admired for their mesmerizing colors, intricate patterns, and graceful movements. However, not all Koi are created equal. Some varieties stand out due to their rarity, making them highly sought after by collectors and enthusiasts. But what truly defines a ‘rare’ Koi fish?

 

Factors Contributing to Koi Rarity

  1.  
    • Patterns: The arrangement and symmetry of patterns on a Koi’s body play a significant role in determining its rarity. Unique or perfectly balanced patterns, such as a well-defined Tancho mark or precise Hi (red) placement, are exceptionally valued.

       

    • Coloration: Vivid and well-defined colors, with crisp edges and uniform saturation, add to a Koi’s appeal. Rare combinations, such as deep metallic gold paired with jet black, are particularly prized.

       

    • Lineage: A Koi’s genetic background has a significant influence on its rarity. Fish from reputable breeders with a lineage known for producing award-winning offspring often fetch higher prices.

       

    • Breeding Difficulty: Some Koi varieties are notoriously difficult to breed consistently. For example, producing perfect examples of Doitsu or Tancho Koi often involves meticulous breeding processes and a lot of patience.

     

 

How Rarity Impacts Value in the Koi Market

 

In the Koi market, rarity often directly correlates with value. Rare Koi varieties are frequently auctioned at premium prices, sometimes reaching tens of thousands of dollars. Collectors are often willing to pay a premium for a fish with exceptional lineage, striking coloration, and flawless patterns.

Furthermore, rarity isn’t just about appearance. A rare Koi with unique traits and a strong genetic background can also serve as a valuable breeding fish, contributing to future generations of high-quality Nishikigoi.

Koi Superior Champion 80bu Showa – the 46th All Japan Koi Show Champion,  

An 80bu Showa refers to a Showa koi fish (a variety of koi characterized by its striking black base color with patterns of red and white) that has reached or surpassed 80 centimeters in length.

  • 80bu: A Japanese way of denoting size categories for koi, where “bu” represents increments of 3 centimeters. Thus, 80bu indicates a koi between 80 cm and 83 cm in length.
  • Showa: A specific koi variety, officially called “Showa Sanshoku,” which features a black body base (sumi) with red (hi) and white (shiroji) markings.

 

Large Showa koi like 80bu specimens are highly prized for their size, vibrant coloration, balanced patterning, and the quality of their sumi (black patterns). They are often showcased in koi competitions where size and beauty are key judging factors.
