Sekiguchi - Tosai - Showa - KOI-7261369

This Showa from breeder Sekiguchi is a young Japanese koi with an immediately appealing appearance. The first thing that stands out is the dominant Sumi (black) that powerfully contrasts against the clear white skin, beautifully complemented by warm Hi (red) on the head and midsection. At a length of 23–26 cm, this Tosai falls into the category of promising young koi that are appreciated by both beginner and experienced enthusiasts. (SKU: KOI-7261369)

Characteristics of this Showa

Visually, the harmonious distribution of the three base colours stands out: the compact, inky black Sumi contrasts beautifully with the clean shiroji, while the Hi refines and gives focus to the pattern. The head features a sharp mask shape that adds character to the face, and the motoguro (black in the pectoral fins) is strong and symmetrical — a classic Showa signature that further accentuates movement.

• Body: straight, well-formed body line with regular scale alignment and bright eyes.
• Skin quality: gloss and clarity over the entire skin; the shiroji looks fresh and clean.
• Pattern: balanced, contrasting Sumi plates with neat Hi on the head and midsection.
• Fins: strong, symmetrical pectoral fins with clear motoguro.

In the pond, this Showa distinguishes itself through its high contrast and calm balance in the pattern: each stroke alternates beautifully between the jet-black zones and the bright white. As a Tosai, the Sumi can further settle and deepen over the coming years; the Hi may also gain some body, while the shiroji generally brightens up further with good water quality and care. It is this development that makes Sekiguchi Showa so exciting to follow.
