From Rejected to Remarkable: Aragoke Koi Makes History

The journey of Aragoke Koi is nothing short of amazing. What was once a discarded variety has now become a star in the spotlight. It all started with Ikarashi Koi Farm, the pioneers of this unique breed. In Hiroshima, Mr. Oyama took the baton and passionately worked to refine Aragoke into something truly special.

And now, the results speak for themselves — an Aragoke Koi has won the prestigious Tsubaki Prize at the All Japan Koi Show. This is a huge moment for the variety and for the breeders who believed in its potential.

Mr. Oyama’s vision is to create koi that not only grow big, but also display bold, evenly spaced scales. The award-winning Koi on the left is the perfect example of that dream brought to life.
