What Judges Look For

Body, quality and pattern — the three lenses, in the general terms judges and catalogues publish.

Published judging discussion returns to the same three lenses. Body conformation comes first: a balanced, powerful frame with a clean head and even proportions for the fish's class. Skin and colour quality come next: lustrous skin, deep even hi, clean shiroji, and sumi that sits with the finish its variety demands.

Pattern is the third lens, and deliberately last: the most artistic pattern cannot rescue a weak body. Within pattern, judges weigh balance along the body, clean edges (kiwa), and how the design suits the variety — bold wrapping for Showa, crisp placement for Sanke.

These are the general criteria as published by the hobby's own bodies. This page does not score individual fish or reproduce any show's internal judging sheets.
