Bekko

The Bekko is a quintessential variety of Nishikigoi, celebrated for its elegant simplicity and striking contrast. Defined by a solid, single-color base adorned with distinct black markings known as Sumi, the Bekko is often described as the "inverse" of the Utsuri variety. The name itself translates to "tortoise shell," a nod to the scattered, ink-like spots that populate its body. There are three primary sub-varieties within the Bekko category: Shiro Bekko (white base), Aka Bekko (red base), and Ki Bekko (yellow base). Among these, the Shiro Bekko is perhaps the most widely recognized and sought after, often appearing as a companion to Kohaku or Sanke in professional ponds. The Sumi on a high-quality Bekko should be deep, glossy, and concentrated above the lateral line and off the head; the fins are generally white but may carry thin black stripes (Tejima). Unlike the Sanke, which it closely resembles, the Bekko lacks the vibrant red Hi markings, focusing purely on the interplay between its primary base color and the dark Sumi. Historically, the Bekko was developed through selective breeding of Sanke offspring that lacked red pigment, eventually becoming a stable variety in its own right. Breeders such as Marudo and Shinoda have refined the variety to ensure that the base color remains pristine—whether it is the snowy white of the Shiro or the deep, saturated crimson of the Aka. The Ki Bekko remains a rarity, cherished by collectors for its vibrant sunshine hue. In a pond, the Bekko provides a sophisticated visual balance, acting as a serene anchor among more flashily patterned koi. Achieving the perfect balance of Sumi placement is the hallmark of a champion Bekko, requiring years of careful observation and genetic selection by Japanese masters.
