Shusui koi was the first Doitsu variety of koi and are one of the only two blue koi! They are a Doitsu (scale-less) version of Asagi.

The absence of scales on this koi can give off a beautiful blue color. Having Hi marks on the cheeks, head, body, and fins is wonderful for this koi.

Shusui The second element of an odd variety partnership is the Shusui, which means “autumn water” in Japanese. At first sight, these mirror-scaled koi seem to have little in common with Asagi, but that variety was first crossed with a German table carp in 1910 by Yoshigoro Akiyama, resulting in the first Shusui.

The color distribution is essentially the same as in the Asagi. but because there are no normal scales to give an overall reticulated effect, the smooth, sky-blue back is instead highlighted by the Doitsu scalation.

In good examples, these armored scales form a regular pattern on the shoulders of the koi and then run in two lines on either side of the dorsal fin, e returning to a single line on the caudal peduncle. A further line is usually present along each flank, roughly following the lateral line.

The most common fault on Shusui is a messy shoulder scale pattern that lacks symmetry. Rogue scales can appear elsewhere on the body, further devaluing the fish. In hard water, the mirror scales can turn grayish or black, and once this happens they never revert back to blue.

A clear head is essential on Shusui, as it is on Asagi. The skin is never snow-white, more of an ice blue, but should be blemish-free.

The distribution of the red and blue on a Shusui determines its subclassification. On Hi Shusui the hi extends up over the back. so that the two contrasting colors are red and dark blue.

These are unsubtle, quite striking, koi. Hana Shusui also have more red than normal, but here it is in the form of an extra band between the lateral line and dorsal fin, with a break in between.

In the best examples, the hi is laid on in a wavy pattern to give a flowery effect. In Ki Shusui, yellow replaces red. This is a confusing sub-variety because if the blue dorsal scales turn black it is easy to confuse with a Doitsu Ki Matsuba.

Another rare, Shusui-like koi is the Midorigoi, which is greenish-yellow with mirror scales. This one is benched in Kawarimono.

Shusui has been crossed with several normally scaled koi varieties to produce interesting variations on a theme. The commonest in the hobby are Showa Shusui, Sanke Shusui and Goshiki Shusui. Crosses with the Ogons (in the Hikarimuji classification) resulted in Ginsui and Kinsui, which used to be quite popular but have now been superseded by more refined Doitsu fish in the Hikarimoyo class.

shusui koi meaning

Shusui, meaning “autumn water” in Japanese, are the Doitsu or mirror-scaled cousin of the Asagi Koi. Rather than the pure white being preferred over all else, the proper head pattern is determined by the pattern of the red and blue on the body of the Koi.
