Study Tategoi part 2 of this promotion starts April 1st 

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 Program for 2022!

We're excited to offer these tosai (koi less than 1-year old) from famous breeders for 2022. 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.

Study Tategoi Part 2 Is Live!

Take a look at part 2 of our study tategoi promotion! There are 26 more varieties of high quality study tategoi available for you to purchase from 16 new top breeders from Japan. Check out part 2 and see what is available!

Featured Koi Breeders Part 1

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

Mr. Shigeru Mano

Mr. Shigeru Mano

Dainichi Koi Farm

In the Koi world, it is hard to find somebody who does not know the Dainichi name. It is synonym of champion quality Koi. As a matter of fact, he won the grand champion at 2020 All Japan Koi Show, the world's no. 1 Koi show.

Because of the quality and the highest demand for the limited supply, we feel very fortunate to be able to obtain Dainichi Tosai and share them with you.

Dainichi are always the first to get sold out. So please do not wait 'till the last minute.

Mr. Takayoshi Omosako

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.

Mr. Mitsunori Isa

Isa Koi Farm

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.

Kage Shiro Utsuri among them is his specialty. In other words, no breeder in Japan breeds this unique variety. We are very fortunate to have them available for our study Tategoi program.

We are very happy to share his Kohaku tosai with you. Please experience and enjoy what his bloodline can do in your pond.

Kaneko Koi Farm

While Kaneko Koi Farm is famous for Kujyaku, Shiro Utsuri and more, he is also known as a developer of Tamasaba goldfish. As a part of his passion for goldfish, he wanted to breed goldfish that koi hobbyists can enjoy with Koi in Koi pond. That is how Tamasaba came to birth. 

Enjoy his high quality Tamasaba grow with your Koi in your Koi pond.

Kanno Koi Farm

Mr. Kazuhiro Hirasawa is one of the young leaders among breeders in Niigata. Goshiki from Kanno Koi Farm are definitely of top quality and highly demanded.

The amazing beauty of Kanno's Goshiki that won the mature champion over Gosanke at the recent All Japan Koi Show is still refreshing!

The tosai available for this study tategoi is from an outstanding female parent. She is 85cm (or 34 inches). She had never been shown at koi shows, but she would definitely have won Best in Variety at the All Japan Koi Show for sure.

Mr. Hirasawa says, "Her body and the high quality and bright beni are the reasons why I picked her for my breeding." We are very fortunate to obtain the first generation siblings of this All Japan class Goshiki. Let's share the dream with Kanno Koi Farm.

Maruhiro Koi Farm

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, defnitely get his Koi.

Mr. Masanori Shinoda

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.
