Among the most striking koi in any pond, the Showa commands attention like few other varieties can. With its powerful combination of black (sumi), red (hi), and white (shiroji), the Showa is a fish of bold contrasts and dramatic beauty. At Crystal Creek Koi Farm, we consider the Showa one of the most rewarding koi a hobbyist can own — and one of the most fascinating to watch develop over time.
The History of the Showa
The Showa Sanshoku — commonly known simply as Showa — was first developed in Japan in 1927 by breeder Jukichi Hoshino. Created by crossing a Kohaku with a Ki Utsuri, the early Showa was quite different from what we see today. Over decades of selective breeding, the variety evolved to feature the vibrant red and clean white markings that now define the modern Showa. Today it stands alongside the Kohaku and Sanke as one of the "Go Sanke" — the three most prestigious koi varieties in the world.
Showa vs. Sanke: Knowing the Difference
New koi keepers often confuse the Showa with the Sanke, as both feature red, white, and black. The key distinction lies in the sumi (black). On a Showa, the black wraps around the body and extends onto the head and pectoral fins — it is a foundational color, not an accent. On a Sanke, the white is the base and the black appears only as smaller markings on the body, never on the head. Once you know what to look for, the two are easy to tell apart.
What Makes a Quality Showa
Evaluating a Showa requires an eye for balance and contrast. Here is what to look for:
- Sumi (black) — Should be deep, lacquer-like, and well-distributed across the body. Sumi that appears washed out or gray is considered a flaw.
- Hi (red) — Vivid, consistent red with clean edges. The hi should contrast sharply against both the white and black areas.
- Shiroji (white) — Pure, bright white that provides a clean backdrop for the other colors to pop.
- Motoguro — The black at the base of the pectoral fins is a hallmark of a true Showa and a key point of evaluation.
- Pattern balance — The three colors should be distributed in a visually dynamic but balanced way across the entire body.
The Showa's Changing Appearance
One of the most exciting aspects of owning a Showa is watching it change. Showa are well known for developing their sumi gradually — a young fish may show relatively little black, which deepens and expands significantly as the koi matures. This means the Showa you purchase today may look dramatically different (and often more impressive) in two or three years. Buying a young Showa is an investment in a fish that keeps getting better.
Caring for Your Showa
- Water quality — Like all koi, Showa thrive in clean, well-oxygenated water. Test regularly for ammonia, nitrite, and pH.
- Diet — A high-quality staple diet with color-enhancing ingredients will help maintain the vibrancy of the hi and the depth of the sumi.
- Space — Showa are active, robust fish that grow large. Plan for at least 250–500 gallons per fish to allow healthy growth.
- Pond depth — A minimum of 3–4 feet protects your koi from temperature swings and predators year-round.
