What is the “Study Tategoi” program?

There are many ways to study koi. A lot of videos and articles are available on the Internet. You can have knowledge on the koi variety, breeder, how they may develop, etc.; but you can never get the experience online.

In order to fully understand koi, nothing is better than raising them yourself in your own pond.  Only by raising these koi in your pond, can you see the color, quality, and how they will grow and develop their beauty. As a hobbyist, you want to get this experience with minimal investment.

Study Tategoi program offers this experience at an affordable price. At Study Tategoi program, we select the breeder of a group of fine quality tategoi (future koi). By offering them randomly picked, Kodama Koi Farm can keep the cost low for you; and you get to enjoy a high-demand bloodline with confidence in quality.

Dive into the Study Tategoi Part 2!

We hope you are enjoying part 1, but we are excited to offer you even more tosai from some of the most famous breeders in Japan. This is a great way to affordably access many different varieties of koi all in one spot. Normally full-grown koi sell for high prices, but with the Study Tategoi program (where koi are randomly selected for you) you can affordably get young koi and watch them grow and develop in your pond.

Featured Koi Breeders Part 2

We're happy to share Taro Kodama's expertise below about these hard-working breeders. Enjoy!

Mr. Futoshi Mano and Mr. Shigeru Mano

Dainichi Koi Farm

I think it is OK to say Yellow Monkey is Dainichi version of Kawarimono or Karashi. According to Shigeru, they used Karashi from Sakai fish farm to develop this variety. He used Sakai's Karashi because they are not only big but also wide unlike other Karashi which looks more pointed.

He explained that Sakai introduced Sakai Kohaku bloodline to Karashi to make them wider. Dainichi yellow monkey comes with so many different color versions. But one thing for sure is that they all have the gene of gigantic growth. Grow jumbo yellow monkey in your pond

Looking for Benigoi that can grow really big? Dainichi now breeds Benigoi with the Red Tiger bloodline

Mr. Hironori Hirasawa

Being a brother of Marusei Koi Farm, it's no wonder that Mr. Hironori Hirasawa likes JUMBO. He loves any Koi that grows big.

When you go to his farm, you can feel his passion. His facility is always full of Koi, especially large ones regardless of the season.

If you want a Koi that is high quality and grows big, definitely get his Koi.

Mr. Masanori Shinoda

Shinoda Koi Farm

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.

We also raise his Tosai Hi Utsuri at our farm. This Koi was Tosai in 2018. She is now 24+ inches at our farm. Every Hi Utsuri in this program has the potential

His Ginrin Showa are descendants of the famous one that won grand champion at the 39th Nogyosai Koi show over Gosanke about 16 years ago. Before nor after that Koi, have I seen any other non-Gosanke beat other Gosanke for the title.

Mr. Takayoshi Omosako

Omosako Koi Farm

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.
