Koi variety guide
Showa Koi Guide
Showa are black-based koi with red and white markings. This guide gives beginners a practical way to identify Showa and understand why the variety can change dramatically as it develops.

How To Read Showa
Showa identification is not only about seeing three colors. It is about how the black, red, and white interact across the whole body.
Black Structure
Black gives Showa much of its identity. It may wrap upward from the body and appear in powerful blocks.
Red And White Balance
Red and white should work with the black rather than disappear under it.
Development
Showa can be difficult for beginners because future black development may not be obvious at purchase.
Buying Caution
Avoid paying for imagined future quality unless the seller can explain age, bloodline, development risk, and why the koi fits your pond.
- Confirm Health FirstCheck behavior, body, fins, breathing, and skin before discussing pattern.
- Ask About DevelopmentYoung Showa may change, so ask what is expected and what is uncertain.
