A white koi that has hi (red) and sumi (black) patterns which are scattered over its body. Taisho Sanke is named after the time period it was first bred, the Taisho period of Japanese history.


Showa or Showa Sanshoku is a black koi with white and red (hi) patterns. The first Showa koi had large amounts of black and red with just a small amount of white.

Utsuri Mono

Utsuri translates as ‘reflections’ and the pattern almost looks like a chessboard alternating from side to side. Shiro Utsuri are most common – a black koi with white patterns all over the body and head.
