Tancho Koi are some of the most admired varieties in the koi world, especially for their iconic red “hi” spot on the head a feature reminiscent of the Japanese flag. Among them, two popular types often cause confusion: Tancho Showa and Tancho Sanke. While they share the same red marking, their body patterns, origins, and overall appearance differ significantly.
In this article, we’ll take a closer look at the key differences between Tanchō Showa and Tanchō Sanke to help you better understand and identify them. “Tancho” refers to koi that have a single, round red spot on the head, with the rest of the body typically being free from red coloration. This marking resembles the red sun on the Japanese flag and is highly prized in koi competitions and collections.
TANCHO SHOWA: Characteristics
Tancho Showa is a variation of the Showa Sanshoku (Showa) koi. While it lacks the typical red patches of a regular Showa, it retains the black (sumi) and white (shiroji) coloration on the body along with the distinct red circle on the head.
Key Features:
• Red spot (hi) on the head only
• White base color
• Prominent black (sumi) markings on the body
• Often has deep, bold sumi that wraps around the body or extends above the lateral
TANCHO SANKE: Characteristics
Tancho Sanke is a variation of the Taisho Sanke (Sanke) koi. Like the Tancho Showa, it also has the signature red spot on the head but features a lighter pattern with more emphasis on white and subtle black markings.
Key Features:
• Red spot (hi) on the head only
• White base color
• Small, delicate black (sumi) spots, usually on the upper part of the body
• No sumi on the head
• More refined and elegant appearance compared to Showa
Conclusion
Meanwhile Tancho Showa and Tancho Sanke may look similar at first glance due to their shared red head marking, they represent two distinct varieties with different patterns and personalities. Whether you prefer the bold, striking look of the Tancho Showa or the refined elegance of the Tancho Sanke, both are beautiful and valued members of the koi family.
