Each type of Koi has its distinct features that make them unique, and careful observation and classification are essential in appreciating and understanding the dazzling diversity of Koi varieties.
Gosanke Group

One of the main groups of Nishikigoi is Gosanke, which includes three types of Koi: Kohaku, Sanke, and Showa.
Kohaku is considered the most popular koi variety because of its simple yet striking pattern of white skin with red markings. The red mark on Kohaku is evaluated based on its shape, size, and placement and should ideally be vibrant and well-balanced. A Kohaku with a perfect pattern is highly sought after and can fetch a high price in auctions.
Sanke, also known as Taisho Sanke, is another popular koi variety in the Gosanke group. Its pattern consists of three colors: white, red (Hi), and black (Sumi). Sanke’s white base skin should be bright and pure, while the red and black patterns should be evenly distributed and well-defined.
On the other hand, Showa has a more complex pattern of white, red, and black painted across their bodies. Showa koi with a well-balanced and evenly distributed design is considered the most desirable.
The Gosanke group is highly valued among koi enthusiasts and is a popular choice for pond keepers due to its striking and eye-catching patterns.
Other Koi Types
Doitsu Koi are a unique type of Nishikigoi due to their scaleless bodies, which give them a distinct appearance compared to other koi varieties. The name “Doitsu” comes from the German word “Deutsch,” which means “German,” as this variety is believed to have originated from German carp. Doitsu Koi have only lateral scales, which run along their sides, and a row of scales along their dorsal and ventral fins. The absence of scales on their bodies makes their underlying skin patterns more visible and prominent, making them highly sought after by koi enthusiasts.
The following table provides a summary of some of the most popular Doitsu Koi varieties, along with their identifying characteristics:
Koi Variety | Description | Characteristics |
---|---|---|
Doitsu Kohaku | A white Koi with red markings | No scales on the body, red markings on the head and body |
Doitsu Sanke | A white Koi with red and black markings | No rankings on the body, red and black markings on the head and body |
Doitsu Showa | A black Koi with white and red markings | No scales on the body, white and red markings on the head and body |
In addition to their unique appearance, Doitsu Koi are known for their hardiness and resilience. Due to their lack of scales, they are more resistant to certain diseases and parasites that can afflict other koi varieties. Overall, Doitsu Koi is a fascinating and valuable addition to any koi pond, prized for its distinct appearance and robust health.
