Maruhiro Sanke – Nisai – 56cm – Unsexed – Certified

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

“A Maruhiro Sanke with bold hi, clean shiroji, and beautifully developing sumi.”

This striking Nisai (2-year-old) Sanke from the prestigious Maruhiro Koi Farm demonstrates everything that makes this breeder internationally respected: bold, uniform hi plates, pristine shiroji, well-placed developing sumi, and a powerful body frame. At 56cm, this unsexed Sanke shows excellent growth potential and the classic Maruhiro thickness through the shoulders, ensuring a strong, symmetrical, and long-term development trajectory.

With a price of £995, this is an exceptional opportunity to secure a premium, hand-selected Sanke from one of Niigata’s most reliable and high-quality Gosanke producers.

56cm Nisai with strong, balanced body structure for long-term growth
