Matsukawabake – The Ever-Changing Koi

Matsukawabake is a striking black and white koi known for its unique, ever-changing sumi pattern—referred to as Henka Sumi in Japan. Bred from Kumonryu and Shiro Utsuri, this variety was created to capture the beauty of constantly shifting black markings.

What sets Matsukawabake apart is its ability to transform over time, with patterns that can shift from pure white to deep black or display a dramatic mix of both. These changes are influenced by factors like water temperature, stress, and seasonal shifts.

Its unpredictable nature makes Matsukawabake a favorite among hobbyists, offering a living work of art that evolves before your eyes.
