kohaku koi different types of kohaku you need to know 2019
In this article. I am discussing about different types of kohaku koi fish variety and its genalogy history.
What are the kohaku koi fish ancestors and how they got their coloration and patterns that we see today.
kohaku koi definition
The kohaku koi is a representative class of the Nishikigoi.
Though its color is plain only white and red.
It reminds all the Japanese of their national flag of Japan.
In the koi world, there is a saying, “Keeping the Nishikigoi begins with the Kohaku and ends with the Kohaku.
First people are attracted by the beauty of the Kohaku koi and charmed by the Showa or the Ogon.
But finally, they go back to the Kohaku koi again.
That means that Kohaku koi is the prototype of the Nishikigoi.
Kohaku koi Origin
It was around 1800 that a red and white koi appeared for the first time.
By mutation, a koi with red cheeks called “Hookazuki” was born from a black carp.
Then a white koi was born from “Hookazuki”
The white koi being mated with a Higoi, a white koi with Hi markings was breed and called “Hara-aka” (red Belly)”.
Later kois with Hi markings on the gill covers “Era-Hi (Red gills)” were breed.
Later than 1830 a “Zu-kinkaburi” whose head is partly red, a “Menkaburi” whose whole head is red.
A “Menkaburi” whose whole head is red, a “Kuchi-beni of which lips are red
An a “Sarasa” which has red and white markings on the back were breed.
In the Meiji era Kohakus spread all over Yamakoshi and were improved.
It was by Gosuke of Utogi that so-called modern Kohaku was breed.
Utogi is a part of Ojiya City now. His real name was Kunizo Hiroi.
He mated a male koi of the cherry blossom pattern with a female which had a redhead.
A Tomouemon inherited Gosuke’s excellent Kohaku and Yagozen and Buheita followed him.
Good white texture is the most important element in the case of the Kohaku.
It must not be yellowish or brownish but should be snow white.
Dark but bright Hi is Preferable.
There are two kinds of Hi one’s base is purple and the other base is yellowish brown.
The former Hi is darker and does not fade away easily but unrefined.

Kohaku is one of the most beautiful koi with its pure white body and intense-red patterns.
The white cannot have a yellow tint, it must be snow-white, and the
Hi (red) must be consistent, evenly colored, without thin, discolored spots. Red is not desirable on the fins.
The edge of the red pattern must be sharp and clear against the white background (this edge is called “kiwa”).
The red pattern should be artistically well-balanced.
One of the most important factors to be considered is the body conformation.
Don’t choose a Kohaku simply because it has a beautiful pattern.
Poor body conformation is usually a result of more serious internal
problems that will eventually result in health problems.

Straight Hi Kohaku
– by patterns on the body:
Omoyo: one step pattern. A continuous, large, unbroken pattern from head to tail.
Straight Hi: Single, continuous Hi pattern, but the red patches are interconnected.
Nidan: two step pattern. Two islands of red color that are not interconnected.
Sandan: three step pattern. (Yondan – four step, Godan – five step, etc.)
Inazuma: pattern resembling a lightning strike; zig-zag pattern.
– by markings on the head:
Tancho: Pure white body with a single roundish red marking on the head between the eyes
(with no other red on the body).
Kuchibeni: red lipstick-like markings, red (beni) on the mouth.
Menkaburi: “hood” pattern – going behind, below the eyes often to the mouth.
Maruten: “crown” on the head pattern – a red mark on the head (similar to Tancho) but with red patterns
on the rest of the body too.
Kohaku are sensitive to water conditions. In hard water they will develop small black freckles (called “shimi”) on the skin.
Softer water will prevent shimi from forming and will also
contribute to the development of the red (beni).
In very young koi the red starts out as a pale yellow and, in time, it changes to orange and later to red.
Males tend to develop the red faster than females, but their color also tends to diminish faster.
Females might take longer to develop the red but their colors will
last longer, this aspect making them more desirable among the hobbyists.
Kohaku There are fundamental points to look for in a kohaku. Pattern for the head, body, the tail, and the fins.
A red marking is indispensable for the head, even if it has beautiful
patterns on the body, a koi without a head Hi will be amoung the first culled.
The ideal shape of the head Hi is a large U spreading over the head,
a head Hi which spreads all over the head is not preferable.
The mouth region should be white, the Hi which spreads down to
the lips, and not covering the cheeks and jaws is also disliked.
The ideal end line of the head Hi is the nose line, and at least down to the eyes.
A head Hi that is neither too large nor too small is preferable.
The head Hi should not spread down to the mouth tip, if it is split in some place, no mouth Hi is acceptable.
The head Hi must not cover the eyes, jaws, and cheeks, but must be as large as possible.
The back should have a pattern well-balanced on both sides. A large mark on the shoulders near the head makes a Kohaku look imposing.
A V shaped white cut on the shoulders is desirable. A continuous pattern from the head to shoulders without any cuts looks dull.
The distance between the last Hi and the tail joint should be about 2cm.
As the fish grows larger, this distance increases, the last Hi spreading
over the tail is disliked, no fins should have Hi.
The skin should be snow white, the Hi deep, each pattern is
different but should show a clean cut edge.
The Kohaku should look imposing, elegant and the pattern well balanced.
The basic factors of Kohaku are, Bright Hi, Sharp pattern edges, no
Hi over the eyes and fins, no Hi markings spreading below the
lateral line, head Hi that does not spread below the nose, and tail Hi that does not spread over the caudal fin.
Kohaku Koi are the most popular Koi in Japan. Kohaku, Sanke and Showa Koi are called the “Gosanke” which means “The Three Families.” In the United States, “Gosanke” Koi are often referred to as “The Big Three.”
Kohaku are white bodied koi with red markings (sometimes more orange than red)…
Ideally the white of the body is like fine porcelain in color, with the
red well-demarcated (not “bleeding”). Red is undesirable on the fins,
and unless specified in a particular sub-variety, not below the eyes or on the mouth.
Several “sub-varieties”, designator terms are utilized with Kohaku type koi:
By Hi: “He”, Red Patterns on the Body:
Straight Hi: Pattern like meandering islands of red that are interconnected.
Inazuma: Interconnected red pattern looking “Like a Lightning Bolt”.
Nidan (Ni is two in Japanese): Two Step pattern. Two islands of red color that are not interconnected.
Sandan (San is three in Japanese): Three Step pattern. Three islands of red color that are not interconnected.
Yondan (Yon is four in Japanese): Four Step pattern. Four islands of red color that are not interconnected.
By Red Markings on the Head:
Kuchibeni: “Lipstick”; with red on the oral lobes.
Menkaburi: With “A Hood on the head”. Going behind, below the eyes often to the mouth.
Maruten: With a “Crown on the head”. A reddish mark, though with more red on the body.
Tancho: With a “Red Sun” marking on head, and lacking other red on the body. Best if the “spot” is bright red, w/o bleeding color, and circular, centered on the head.
Koh-haku koi are the cornerstone of any serious koi collection.
They are fairly simple in appearance, with red markings on a white body.
But simplicity aside, this is undeniably the most important and
most fundamental koi variety.
Koh-haku form the root breeding stock of many other varieties,
and they commonly win the “grand champion” award at prestigious koi shows.
It is said “appreciation of koi starts and ends with Kohaku”. What that means is Kohaku was the first class to be bred consistently or stabilized in about 1890.
It also means that after a person has studied all of the classes of koi and has become experienced, they
will come back to appreciate Kohaku for its simplicity and beauty.
I will keep the amount of Japanese terminology to a minimum in this lecture.
A Japanese term dictionary will be available soon in KOIUSA magazine and on the AKCA website.
Before I continue on Kohaku, I want to take a minute to discuss judging points common to all classes.
Koi are judged as a whole or holistically and are not judged on a positive or negative point system.
Negative points can come into play in close contests.
Koi are judged side by side based on what we see today and not what may be there next week or next year.
Japanese Judges have a disadvantage in often being able to
recognize bloodlines, which can cloud their “judge for today”
decisions because they know which koi cost more and has more potential.
A Japanese Judge once answered a question on why a koi won an
award replying, “because it was the most expensive fish”.
Koi may lose today only to come back to win tomorrow based on the competition tomorrow.
First, the koi cannot be missing anything like a fin or have any
abnormalities like a pushed in mouth all of which will disqualify the koi from judging.
The exception is the second set of barbels.
Second the koi must be healthy and not show signs of disease or
parasites, which could disqualify the koi from judging.
An exception is made for split fins or bruises judged to be caused during transportation.
Third, is the importance of body conformation.
Broad, thick body shape of female koi is preferred giving an
imposing appearance when compared to the thin trout shaped body of a male koi.
Shape and size of the fins are important to be in proportion to the body.
The head shape is important that it not be too short or too long or turn to one side.
The koi when viewed from above should be symmetrical on both sides and not have one side flatter than the other.
Even the way a koi swims is taken into account on conformation.
Not all female koi hold their eggs well, which could affect conformation.
Fourth, in my opinion is quality of skin and deep, vibrant colors, which makes koi “living jewels”.
This also includes how well the koi is “finished”, are all of the colors up, and is there a good sheen on the skin.
It is conformation and quality that will catch a Judges eye from a distance.
Fifth is pattern that is artistically balanced and not front, tail or side heavy.
Pattern must also be proportional to the size of the koi and not have
a small pattern on a huge body or a huge pattern on a small body.
Last is uniqueness or character usually of the pattern on the head that makes this koi special.
Now for Kohaku.
We have a snow white (shiro) base color with a red (hi) pattern. The pattern may be stepped or continuous. The white must be without blemish or yellow tint.
The hi may be any one of the many hues from deep persimmon
orange to Ferrari red but the red must be thick without any thin
spots and the pattern must be the same color from head to tail.
Some Judges prefer the persimmon orange hi to the Ferrari red
because the orange appears soft and the purple red appears hard and gaudy.
Kohaku must have red pattern on the head.
The pattern on the body must be artistically balanced and the kiwa
or rear edges of each spot must be sharp like cut with a razor.
A new bias in Japan has started to favor bloodlines that have the
kiwa stop at the edge of each scale forming a scalloped edge rather
than a straight edge across the center of a scale.
The front edge of each spot (not on the head) may have blurred red color that is called “sashi” or insertion.
Sashi indicates the koi is still improving in quality and is not finished yet.
It is elegant if a Kohaku has a white nose and a white area with no
red pattern just in front of the tail called a “tail stop” and several other names.
Some subtleties of pattern not liked are a totally red head or red
down the face to the nose that are heavy in appearance.
Red pattern wrapping below the lateral line suggests a future koi
when the red and white are better balanced.
Red spots below the lateral line are disliked. The lateral line is a raised sensory organ running the full length of a koi half way up the side of a koi.
A red head pattern with an additional red lip mark is called
“kuchibeni” and can be cute if it balances the overall pattern.
Red pattern at the base of the pectoral fin was considered
unfavorable but is being accepted now if it adds to the overall balance of the pattern.
Red into the tail or into the dorsal fin is still disliked.
Kohaku tend to get black specks “shimis” in hard water with high pH.
How many types of koi fish are there?
Types of Koi Varieties. There are over a 100 different types of koi (Nishikigoi).
Can you have koi fish in a tank?
Keep koi in large aquariums for a few months at a time. If you live in an apartments, you may have to keep koi in aquariums for their entire life.
That is possible, as long as you do not overcrowd the aquarium with too many koi. … Your tank should have 1 cubic foot per 1 inch of koi fish length.
