Showa Koi Collection

The Showa variety is one of the classic Japanese koi, developed in the early 20th century. Known for bold contrasts of beni (red plates), sumi (black), and shiroji (white base), Showa symbolize strength and harmony. Hand-selected in Japan, each fish is chosen for pattern, skin quality, and growth promise.

Within this collection you’ll also find striking subtypes such as Doitsu Showa, Tancho Showa, Ginrin Showa, Goshiki Showa, and Kin Showa. These variations highlight how diverse this koi fish line can be, from mirror-scaled elegance to metallic sheen.

How to choose a great Showa

  • Balanced color placement with crisp kiwa (edges).
  • Strong body shape and even growth potential.
  • Deep, stable sumi that anchors the pattern.
  • Bright, unblemished shiroji for clean contrast.
  • Metallic or Doitsu types: look for even shine and neat scalation.

What makes Showa different from Sanke koi?

Showa display red, white, and black across the body; Sanke are red and white with black only above the lateral line. Showa often show black on the head; Sanke should not.

How big will my Showa grow?

With proper care and genetics, many Showa reach 24–30 inches. Maintain excellent water, steady feeding, and space for swimming to support growth.
