In the following article, we’re covering all things Utsurimono Koi, from understanding their distinct characteristics to mastering their care and making informed purchasing decisions, and more.

Introduction to Utsurimono Koi

Utsurimono Koi, with their captivating patterns and vibrant colors, have long been a symbol of grace and beauty in the world of ornamental fish. The term “Utsurimono” literally translates to “reflections” or “reflecting ones,” aptly capturing the essence of these fish.

Initially perceived as a defect by koi breeders, Utsurimono Koi have since proven their worth, earning a special place in the hearts of koi enthusiasts and breeders alike. Their unique appearance, characterized by a sumi (black) base that emerges beneath their primary color, creates a mesmerizing reflection-like pattern.

This pattern is further accentuated in the three main varieties of Utsurimono Koi:

  • Shiro Utsuri (white with black)
  • Hi Utsuri (red with black)
  • Ki Utsuri (yellow with black)

Each variety offers a distinct visual appeal, making them a prized possession in koi ponds worldwide.

Utsurimono Koi: A Closer Look

The allure of the Utsurimono Koi lies in its striking contrast of colors. Each of the three varieties is defined by a dominant color, be it white, red, or yellow, set against a deep black base. This juxtaposition creates a reflection-like pattern, giving the Utsurimono its name. Among the oldest of its kind is the Ki Utsuri, which dates back to 1899 and was once sold at premium prices. By the 1920s, the Shiro Utsuri and Hi Utsuri varieties emerged, further enriching the Utsurimono family.

Key features to identify an Utsurimono include the presence of sumi at the mouth, base of the pectoral fins, and tail base.

The strength and quality of the black (sumi) are vital, as Utsurimono are fundamentally black koi.

Another distinguishing feature is the Menware or “broken mask” – a bolt of sumi running down the face between the eyes. However, its absence doesn’t diminish the koi’s beauty. The clearer the primary color field, devoid of any black specks or shimi, the more visually appealing the koi.

With their reflective patterns and rich history, these fish are a testament to nature’s artistry. Whether you’re a seasoned koi breeder or a new enthusiast, the charm of the Utsurimono is hard to resist.
