Shiro Utsuri are non-metallic black-and-white koi in the Utsurimono family. Their sumi often creates broad bands that wrap around the body, with white forming contrasting areas. With only two colors, the relationship between black, white, and the fish's shape is especially easy to appreciate.

How to Identify Shiro Utsuri
- Only black and white in the body pattern, with no red component.
- Broad black areas that can continue onto the sides and head.
- An overall Utsuri pattern rather than isolated dorsal black spots.
Compare Similar Varieties
Compare Shiro Bekko for smaller separated sumi on a white ground. Compare Showa if red markings are also present. Black-and-white color alone does not make the distinction; the distribution of sumi is the useful clue. Watch the fish turn so the visible top pattern does not hide its side markings.
Choosing and Observing Shiro Utsuri
Look at the whole fish before deciding whether one patch is too large or too small. Strong contrast, clear white areas, and a balanced body can make many different arrangements attractive. Young sumi may develop or recede, so avoid treating a faint mark as a guaranteed future band. Dated photographs offer a better record than predictions.
