Otsuka Doitsu Gin Rin Chagoi – Yonsai – 70cm – Unsexed – Certified & Microchipped

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

“A powerful 70cm Otsuka Gin Rin Chagoi with superb sparkle, presence, and jumbo frame.”

This impressive Yonsai (4-year-old) Doitsu Gin Rin Chagoi from Otsuka Koi Farm demonstrates why this breeder is renowned for producing large, strong, and high-quality koi. At 70cm, this koi already exhibits a commanding presence, thick body volume, and clean, even Chagoi colouration, enhanced by bright, consistent Gin Rin scaling that adds sparkle across the entire body. Its friendly temperament and approachable nature make it a perfect centrepiece for any pond.

With a price of £1500, this is a rare opportunity to secure a premium, hand-selected Japanese Gin Rin Chagoi from one of Niigata’s most respected breeders.

Why This Koi Stands Out

• Brilliant, uniform Gin Rin scaling with exceptional sparkle

• Clean, warm brown Chagoi tone providing a refined, balanced look

• Strong, thick body frame with true jumbo growth potential

• Friendly, classic Chagoi temperament – ideal for hand-feeding and pond confidence

• Impressive Yonsai size at 70cm, ready to make a statement in any pond

Otsuka koi are internationally respected for their powerful frames, clean scaling, and long-term growth potential. This Doitsu Gin Rin Chagoi embodies all of these traits, making it a standout choice for serious hobbyists and collectors.
