Key Features

Solid base color with contrasting sumi (black) markings, absence of metallic sheen, and clear separation between colors.

Pattern Description

Bekko should have well-balanced, sharp, and clear sumi (black) markings that are distributed evenly across the body. The sumi should not overlap the lateral line and should enhance the beauty of the base color without dominating it.

Name Meaning

Bekko translates to 'tortoiseshell', reflecting the pattern's resemblance to the shell of a tortoise. This name highlights the contrast and interplay between the sumi (black) markings and the koi's base color.

History

The Bekko variety is believed to have been developed from the Sanke (Taisho Sanshoku) by selectively breeding for specimens that showed only black markings over a solid base color, removing the red (hi) patterns. The exact origin date is unclear, but it is considered a traditional variety.

Ideal Characteristics

Judges and collectors look for Bekko with a strong, vibrant base color, clear and well-defined sumi (black) markings, and a balanced pattern that enhances the koi's overall appearance.

Commonly Confused With

Bekko can be confused with Utsurimono, especially Shiro Utsuri, due to the black and white coloration. The main difference is that Utsurimono have a more dynamic, wrapping pattern of sumi, while Bekko have more discrete, isolated sumi markings.

Judging Criteria

Judges evaluate the clarity and quality of the base color, the sharpness and placement of sumi (black) markings, the balance and harmony of the pattern, and the overall body conformation and health of the koi.

Identification Tips

  • Look for solid base color with contrasting sumi (black) markings.
  • Sumi should not dominate the body and should be well-defined without bleeding into the base color.
  • Check that the koi is not metallic, as this would classify it differently.
