Hajiro - (hah GEE row) A black koi with white on the tail and pectoral fin tips. The Karasu, meaning crow in Japanese, is a very old variety with black fins, a black body and a white or orange belly. The very similar Hajiro is a black Koi with a white nose and white-tipped pectoral fins, which makes it more visible in the water. The Hageshiro adds a white head to this color combination, while the Yotsujiro's fins are completely white. All four Koi should display deep and even sumi, darker that of the Magoi.
