Showa Sanshoku

Showa Sanshoku is the formal name for Showa, the black-based three-colored koi carrying red hi and white markings. The variety developed in Japan and has changed over time from darker, heavier fish to modern lines that may show bright white fields and refined pattern. A useful way to recognize Showa Sanshoku is to look for sumi that feels part of the body structure, often wrapping low or reaching the head, rather than sitting only as small accents.

For owners and breeders, the challenge is reading development. Showa Sanshoku may look unfinished for several years, especially when the sumi is still rising under the skin. Good husbandry gives the fish time: clean water, room to grow, steady seasonal feeding, and minimal stress during moves or treatments. Buyers should ask about age and bloodline when possible, then evaluate whether the red, white, and black can mature into a balanced pattern. A dramatic young fish is not always the one that finishes best.
