Utsurimono

Utsurimono are black-based koi with a second color wrapping through the body pattern.

Main types

Identification

Unlike Bekko, Utsurimono should feel black-based. Sumi often wraps around the body and may appear on the head and pectoral fin bases.

FeatureUtsurimono cueCompare with Bekko
Base impressionBlack-based fish with a second color wrapping through the pattern.Bekko looks like black marks placed on a lighter base.
Head sumiBlack on the head can support identity and balance.Bekko generally should not feel head-heavy with black.
MotoguroBlack at the base of pectoral fins can strengthen the classic impression.Absence is not automatic failure, but check balance.
PatternStrong contrast without chaos; body should still be readable.Random dirty marks weaken both Utsuri and Bekko.

Do not confuse every black-and-white koi with Shiro Utsuri

Scale type, white placement, metallic luster, and the structure of the black pattern separate several look-alike varieties. Use this sequence before judging pattern quality.

CandidateKey identification cueWhat separates it
HajiroThe body is essentially black, with white most clearly limited to the pectoral fins.It does not show the wrapping black-and-white body pattern expected of Shiro Utsuri.
Shiro UtsuriNormally scaled black base with white pattern and Utsuri-style sumi wrapping through the body.Head sumi and motoguro may support the classic Utsuri impression.
KumonryuDoitsu appearance with few scales and cloud-like black pattern over white.The black pattern may change markedly with environmental conditions; red markings indicate Beni Kumonryu.
KikokuryuKumonryu characteristics combined with metallic luster across the body.The metallic sheen is essential; red or gold pattern leads to Beni or Kin Kikokuryu.

Beginner note

Look for balance between black and the second color. Strong sumi is important, but avoid fish where the pattern feels chaotic or the body line is weak.
