The Izumiya Koi Farm in Yamakoshi is said to be the first ever retail outlet in the Yamakoshi area, a true professional in the Koi world. He breeds the very best Yamabuki Ogon in the entire world, they are truly wonderful, available to buy from 2 years old up to all ages and all sizes, you will see many Koi at the facility well approaching 1meter.
Mano Izumiya also breeds some very nice Kohaku and Sanke, having bred a Kohaku that won Grand Champion at the Nogyosai in recent times. A very big facility with very big Koi. Mano San is always involved with day to day running of the company along with his son who is also becoming very similar to his father. Mano San had a very bad time during the recent earthquakes with many of the disaster pictures being of his Koi. The building is still slightly slanted, and you can see the water level sloping to one side when you go in there, giving a very strange feeling as you walk around. Fortunately he is back at full power and doing what he does best.
