The Sakasa Kebari or reverse-hackle fly, is an artificial fly most associated with the Japanese style of tenkara fishing but can be used in most freshwater fly fishing. The Sakasa Kebari is usually defined by firstly, its reverse hackle and secondly, by its simplicity[1] as compared to western style flies. This fly was originally created to be used in the small, high gradient streams in Japan while fishing for native trout and char.[2]
One of the main differences between Sakasa Kebari style flies and their western counterparts is that while western style flies tend to mimic specific insects in as much detail as can be accomplished[3] the Sakasa Kebari is more impressionistic, what is often called an attractor fly. Instead of trying to incorporate an insect's details, it tends to be more general, allowing the target fish to 'connect the dots'.[2]
