Ogon koi are a single solid colour with a metallic appearance. This variety is very popular, particularly with those new to keeping koi. These fish can be a variety of attractive colours. Cream specimens are rare and the most popular choices are bright yellow (Yamabuki Ogon) and Platinum (Purachina Ogon). This type of koi does not have reticulated scales. They are striking specimens and offer beauty in simplicity. They are bred in large numbers due to their popularity and so competition is fierce at shows and there are strict criteria for judging these fish.


Yamabuki Ogon koi fish serve as an example of the beauty to be found in a single-colored Koi fish. This type of Koi originating from Japan is a solid golden color with an alluring metallic sheen. Their bright yellow shade stands out, especially in the green-tinted water of low-filtered Koi ponds, and their metallic finish makes them eye-catching in the best way.

The word Ogon (OH-gahn) translates as ‘golden’ and was historically used to refer to any metallic fish. However, nowadays, more and more koi keepers and breeders use the word ‘Ogon’ to refer to only single-coloured metallic koi. When most koi keepers hear ‘Ogon’ they tend to think of the Big Three which are:

  • Yamabuki
  • Orenji
  • Platinum

But other Ogon koi varieties are becoming popular as well which include:

  • Mizuho
  • Mukashi


Color Specifications


Yamabuki Ogon Koi fish is a single golden color. They come in various shades of yellow, from a dazzling, light eggshell shade to a brilliant daffodil hue to a darker mustard tint. Young Yamabuki Koi usually start with a lighter shade of yellow and darken as they mature.

According to uniform standards, a Yamabuki should have no orange spots. These spots sometimes develop on the head and body of a Yamabuki Ogon, especially on ones that are a dark, deep yellow at a young age.

Ogon koi are arguably one of the easiest koi varieties to judge due to their single-coloured simplicity compared to the 5 colours of the Goshiki or the complex reticulation of the Koromo. However, such simplicity requires perfection.

While a small colour bleed or a misaligned scale may be ignored on other varieties, on the pure white body of the Platinum Ogon, such imperfection is much more obvious and difficult to ignore. Therefore, they are judged much more strictly than many other varieties. In addition to this, because of their popularity, many breeders will breed lots of them allowing them to be very strict with the culling and selection processes, which results in only the very best koi being sold and imported.
