Sekiguchi - Tosai - Showa - KOI-7260527

This Showa from breeder Sekiguchi immediately shows why Japanese koi are so beloved: bright shiroji that strongly contrasts with deep hi over the head, shoulder, and body, complemented by well-placed sumi accents. With a length of 22–25 cm, this Tosai is among the young, fresh additions that beautifully develop in the pond. (SKU: KOI-7260527)

Features of this Showa

The pattern is nicely balanced: powerful red plates lead the eye from the head over the shoulder to the midsection of the body, while the black sumi predominantly presents itself on the sides and around the middle segment. The white skin is strikingly bright, which, together with the intense deep colour, creates a refined, tripartite contrast that is typical of a quality Showa.

• Pattern & contrast: balanced hi plates with characteristic, spot-shaped sumi markings that give this Tosai extra identity.
• Skin quality: shiroji is clean and shiny; the skin shows a healthy lustre and the scales are symmetrical and tight.
• Fins: well-formed; clear sumi development in the left pectoral fin, with a lighter right fin for visual dynamics.
• Build & appearance: youthful but already nicely proportioned, with bright eyes and a calm, powerful presence.

As a Showa in the Tosai age, you can expect further development: sumi may still come through and become denser, spots may show cohesion, while the hi usually deepens and rounds off. With good water quality and nutrition, this koi will flourish beautifully in both colour and body.
