Izumiya Yamabuki Ogon – Nisai – 55cm – Unsexed – Certified

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

“A classic, high-lustre Izumiya Yamabuki Ogon with huge potential.”

This clean and elegant Nisai (2-year-old) Yamabuki Ogon from the legendary Izumiya Koi Farm displays everything that has made this breeder world-renowned: a soft, pastel-gold tone that will deepen with age, flawless metallic sheen, and a long, streamlined body built for growth. At 55cm, this unsexed Yamabuki demonstrates excellent conformation, symmetry, and a thick body line that promises impressive size as it matures.

With a price of £1,200, this koi represents a rare opportunity to own a premium, hand-selected metallic yellow from one of Japan’s most trusted bloodlines.

Why This Koi Stands Out

• Soft, luminous yellow (ki) with metallic lustre and excellent colour stability
  

• Strong, streamlined body designed for long-term growth and jumbo potential
  

• Clean, even scalation and early development of reticulation
  

• Balanced, elegant presence ideal for show or standout pond centrepiece
  

• Classic Izumiya frame providing strength and visual impact
  

• Excellent early colour development, perfect for future maturation
  

Izumiya Yamabuki Ogon are internationally recognised for vivid metallic pigmentation, strong frame, and long-term colour stability. This koi embodies all these traits, offering superb potential for serious collectors and hobbyists alike.

A refined, high-impact Yamabuki Ogon with exceptional growth and developmental prospects.
