Go Sanke, most important

written by Hugo J. Smal

During the Japanese Edo period (1603 – 1867), the successive Shoguns (rulers of military castes) always came from three closely related families: Mito, Kishu and Owan. They are known as Tokugawa Go-Sanke, which are considered the most important genera of the period. As a tribute to them, the three most famous variants of the Nishikigoi (Kohaku, Showa Sanke and Taisho Sanke) were named Go-sanke.

Another koi variant, not even Utsuri, could belong to the Go-sanke class. After all, there were only three families with that name … There are about 150 different koi species today. All with their quality requirements and with their enthusiasts. It is therefore quite possible to transform the pond into a true colour festival. Most enthusiasts do that too. Me too. Still, there’s something to be said for focusing solely on the Go-Sanke class.
Big prizes on shows are only given to these three types. After the Asagi, they are the oldest varieties. They are the true ambassadors for the koi hobby. For example, a man like Peter Waddington, writer of Koi Kichi, really only talks about Go-Sanke. You will not find many other koi species on his farm. Yes, maybe a Bekko or an Utsuri and the occasional Shusui or an Asagi. But it ends there.
All koi knowledge comes together in this class: the contrast blackfish (Showa Sanshoku) and whitefish (Kohaku and Taisho Sanke). The colours red, black and white, which are the main koi colours. The most famous koi come from this class: the Kato Showa, which Takeo Kuroki says has never surpassed quality. The Crown Sanke whose perfectly balanced white and black markings are famous. And Loran who shows like no other fish how great the beauty and therefore the value of a koi can be. All of the Japanese koi cultures join the Go-Sanke class and all demands placed on other species originate from these three most respected koi.

Sumi or Shiro

Taisho Sanke and Kohaku are white fish with Showa Sanshoku being black. The differences are usually clear, but when a Kindai Showa (modern Showa) has to be assessed, for example, it can become difficult. Kindai Showa is approaching the Taisho Sanke very close. Remember that blackfish usually shows Motoguro. This is a round sumi mark on the pectoral fin against the abdomen. A white variety with Sumi markings usually has sumi stripes on those fins. It is also said that the sumi of the Showa resembles that of a tiger while that of a Sanke resembles the markings of a jaguar. If you can not figure it out at all, you can always look in the mouth. If there is black there, then it is a blackfish.

Kohaku

All koi with a red pattern is judged by the Kohaku patterns. That is why it is extremely important to get to know them well. Study them as often as you can.
The white ground of the Kohaku and any other white fish is called Shiroji. In the past, not too much attention was paid to this. The red markings were considered more important. It is now recognized that the red markings are corrected by a perfectly white background. It must be snow white. As the koi grows, fukurin becomes visible. Fukurin is the skin of the koi. In small specimens, the scales are tightly together and nothing is seen of this skin. In large specimens, the skin appears between the scales and forms the highly valued net pattern.
Kohaku has different patterns. There are the step patterns Nidan, Sandan and Yandan (successively two-, three-step and four-step) of which Sandan is the most classic. The straight hi has a mark from head to tail. This is called Inazuma when the marking has a lightning bolt character. Kuchibeni is called the Kohaku which has red lips. A Maruten Kohaku has a round mark on the head in addition to further markings. Only a round mark on the head is called Tancho Kohaku.
The last markings must stop a little before the tail. This balances the fish and significantly increases its value. Attention should also be paid to the markings on the head. She is the face of the carp. It is best when it is in balance with the back mark.
Always make sure that the back of a mark, where the red scales over the white fall (kiwa) is always sharply lined. On the front, where the white scales fall over the red (Shashi), this applies less.

Taisho Sanke

Ultimately, a Taisho Sanke is nothing more than a Kohaku with the addition of sumi patterns. Everything above about the Kohaku therefore also applies to the Taisho Sanke. It is important that the Sanke, as it can be called shortened, has a sumi mark on the shoulder, at the end of the dorsal fin and on the tail. They are necessary.
All other Sumi markings are incidental. Here, too, a whitetail set is important. If it is preceded by a red and only then a black, it is very elegant. Any other order is not appreciated. There should be no sumi on the head. The pectoral fins preferably show equal sumi stripes. That gives the fish a nice balance.

Showa Sanke

This black koi variety should also have a nice Kohaku pattern. However, the black markings are much more massive than those of the Taisho Sanke. Wherewith the Sanke the sumi markings are only spots on a red white body, the Showa must have the three colours in balance. Assume that the classic Showa de Shiro markings should cover about 20 per cent of the total. Very important are the markings on the head and the motoguro. The one on the head should be interesting and give the fish its character. Preferably a red mark is cut there. The motoguro must sit nicely round against the belly on the pelvic fins. Here also a whitetail set, preceded by a Sumi marking.

Ginginrin and Doitstu

Benikikokuryo

All koi in the Go Sanke class can have silver or gold sparkles on the body. Ginrin stands for silver, kinrin for gold. They give the fish extra beauty and are therefore highly appreciated. Almost all koi varieties also have a Doistu variant. Doistu means that the carp have no scales or only a scales line on the back and along the lateral line. These fish usually display their colours more beautifully and often grow larger than the scaly carp. They are therefore in demand. In competitions, they usually do not turn heads because it is much more difficult to grow a scaly carp undamaged.

 

In addition to the Kohaku, Sanke and Showa, there are a large number of other koi species.

Bekko

When Taisho Sanke is crossed with Taisho Sanke this results in Sanke, Kohaku and Bekko. The Kohaku are inferior and are therefore thrown away. The good specimens Sanke and Bekko grow up. Important with the Bekko is the Shiroji and the Sumi markings. The most beautiful black on Bekko is Sashi Sumi. At the front of the markings fading black due to the overlapping white scales while the back shows a sharp Kiwa. Sashi resembles fleeting brushstroke on black lacquer.

 

Utsurimono

There is three types of Utsurimo: Ki Utsuri (black with yellow markings), Hi Utsuri (black with red) and Shiro Utsuri (black with white). The latter is the most important! Good Ki and Hi Utsuri are rare. The Utsurimono varieties are most noticeable because the black markings at the base of the tail show themselves in a chessboard pattern. The word much appreciated when the two colours on the head are about the same size. For the rest, Sumi is seen in the same way as that of the Showa Sanshoku.

Asagi

Koi with a dark or light blue back, orange or red cheeks, pectoral fins and belly are Asagi. This variety is probably the first to be raised from the wild carp some 160 years ago. There are three types of wild black carp: Tetsu-Magoi (iron carp), the Asagi-Magoi and the Doro-Magoi (mud carp). The Asagi Magoi has dark blue scales and strong fukurin on its back. The net pattern only appears when the Asagi is fully grown. This is further enhanced when a dark area appears in the centre of each blue scale. The Asagi’s head should be clean and the red on the pectoral fins should be no more than a third of the fins. When it is the same on both fins, it provides a good balance. There should be no spots on the head and it should also be snow-white.

Shusui

Shusui is the only Doitsu koi to be judged separately in competitions. The head should be light blue and the back dark blue. There should be no dark spots on it. The tip of the nose, the belly and the roots of the pelvic fins are red. The row of scales on the back make the Shusui extra attractive.

Ogon

The solid coloured Ogon is perhaps the most popular all over the world. The Yamabuki (yellow) Ogon is named after a famous Japanese rose. A good copy shines like pure gold. The Platinum Ogon shines, as the name says, like platinum. When fukurin becomes visible, the fish gains in beauty. The Ogon is famous for its friendly nature. When a silvery sparkle is visible on every scale, we call the fish Gin Matsuba.

 

Kujaku: A Gin Matsuba Ogon with red or yellow markings is called Kujaku.
Goshiki: This strain is also obtained by crossing Kohaku with Asagi. Here, however, the dark blue markings do not appear on the red. It appears on the white scales.
Koromo: Cross between Asagi and Kohaku are called Ai-goromo. In Sumi-goromo, the red scale has a dark mark in the middle. 
Kumonryu: This is a white carp with black markings. Those sumi markings should not appear on the head. Motoguro is appreciated. Kumonryu is often reminiscent of the panda bear. Very special is that the black markings can change every year. Buy the Komunryu as white as possible.
Chagoi: Brown Ogon. Is praised because the fish is very easy to tame. This affects the other fish positively. A Chagoi in the pond simplifies koi keeping. The Chagoi grows very quickly and can take on considerable dimensions.
Ochiba Shigure Brown Ogon with grey to blue markings. It is obtained by crossing Chagoi with Soragoi (grey).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

There are lots of other Koi varieties. Almost 150. Too much to share in this blog. But if you did become curious. We are very happy to show you around at the Goyang Koifarm.
