Marushin Gin Rin Showa – Nisai – 47cm – £695

Premium Japanese Koi for Sale – Delivered Direct to Your Door (UK Mainland)

“Striking Gin Rin Showa with explosive colour, crisp sumi, and top-tier sparkle.”

This beautifully refined Nisai (2-year-old) Gin Rin Showa from the renowned Marushin Koi Farm displays everything that makes this breeder a global leader in high-grade Showa: vibrant, lacquer-red hi, clean, bright shiroji, sharp, well-positioned sumi, and brilliant Gin Rin sparkle across the entire body. At 47cm, this koi carries a strong, well-proportioned frame built for long-term growth and impact.

With a price of £695, this is an exceptional opportunity to secure a premium, hand-selected Gin Rin Showa from one of Niigata’s most respected breeders.

• Crisp, well-positioned sumi showing strong shape and future refinement

• 47cm Nisai with a strong, balanced frame and excellent growth potential

• High-impact, show-quality appearance — perfect for collectors or pond centrepiece

• Sourced from Marushin’s premium spawning for elite pattern and colour
