(All Japan Koi Show) Grand champion Kohaku

Mr. Kazuyoshi Hiroi and Mr. Nobuaki Hiroi

Hiroi Koi Farm is one of the most established breeders with 80 + years of history in Niigata, Japan. Kazu and Nobu, the twin brothers says "they are very fascinated with the chance Koi can make.

Koi change its body shape, color and pattern as they grow. They have been famous for Doitsu Showa and Ginrin Showa.

What amazes us is that he always challenges new varieties and still produce high quality Koi. Producing high level Koi at one variety is hard enough.

The Hiroi twin brothers constantly add new varieties and seems easily breed such high quality ones. One of varieites is Doitsu Showa, Kohaku, Goshiki and Doitsu Sanke that is what makes Hiroi Koi Farm a must-visit destination. No other places offer this many and quality koi. Please get at lease one. Or more.

Mr. Mitsunori Isa

I must say that Isa Koi Farm and Dainichi are the two most popular breeders in Japan.

Isa's Showa has many features to enjoy, but my favorite quality is their strong bodies.

Even males can build such powerful shapes, just like the Kokugyo prize winner.

If you can not find what you look for at Maruhiro Koi Farm, chances are that you will not find it any other places. He is one of buyers' first and last stops in Niigata.

Mr. Takayoshi Omosako

There is no question that Omosako Koi Farm is the very best breeder of the Shiro Utsuri variety.

Taking the highest quality as granted, the body of his Shiro Utsuri is very hard to compete with. No Shiro Utsuri from other breeders can have the quality and the size in one. This is why his Shiro Utsuri surpasses everybody else's and always wins at the All Japan Koi Show.

It is very appreciated that Mr. Omosako consistently helps us obtain his valuable tosai and makes them available for you, our clients.

Mr. Hirokazu Oyama and Son

Mr. Oyama, a former leader of Hiroshima district of Nishikigoi association, produces classic type of Koi as well as unique types. Taking Gosanke as granted, he is also specializes in the unique varieties that few other breeders have like Ginrin Chagoi.

If you don't have a Ginrin Chagoi in your pond we highly recommend getting one or more from Oyama Koi Farm in this years study tategoi.

Mr. Shinsaku Sakazumi

Mr. Sakazume thinks Koi breeders must be an artist with breeding skills. Mr. Sakazume definitely fits into the definition of the breeder.

With his pride as an artist and the skill, he became a master of Aigoromo. Aigoromo is a variety that has indigo on its Kohaku pattern.

The contrast of its Ai (indigo) and the show white is beautiful.

As the production of Aigoromo itself is small and limited, I encourage you should not miss this great opportunity to get his world famous Aigoromo.

Mr. Masanori Shinoda

When we talk about Shinoda Koi Farm, Hi Utsuri, Doitsu Showa and Ginrin Showa are the reason to visit.

 His Hi Utsuri is especially second to none. Just like Omosako Shiro Utsuri, no breeder can touch Shinoda’s Hi Utsuri.  His Hi Utsuri is a regular winner of Best in Variety award at All Japan Koi Show. As a matter of fact, he won the title for the last 3 consecutive years.

Raised From Tosai At Kodama Koi Farm

Mr. Yoichi Taniguchi

We are lucky. They are the babies of the famous Ginrin Matsukawabake, Best in Variety Winner at the 55th All Japan Koi Show in 2025. Mr. Taniguchi, when I visited him last fall, proudly told me that this Koi spawned this year.

I told him I wanted the babies, but he was not sure how many he can spare as it was not a big spawning. I visited him again after I saw her history at the All Japan Koi Show and asked again.

They are available for Kodama customers. Get the champion bloodline Ginrin Matsukawabake for your pond!
