Bekko Koi are among the simplest and most elegant koi varieties. The term 'Bekko' translates to 'tortoiseshell' in Japanese, reflecting their clean appearance with scattered sumi (black) markings over a solid base. They come in three color variations: Shiro Bekko (white base), Aka Bekko (red base), and Ki Bekko (yellow base). Bekko are closely related to Sanke koi but lack the red (hi) markings. Their simplicity and striking contrast make them a favorite among koi enthusiasts, especially for beginners who appreciate easily identifiable patterns.
