The Takayama Sakasa Kebari is the tenkara fly that completes our set of 4 flies. Offered in size 16, it's our smallest tenkara fly. Unlike in Western fly fishing, where a lot of people believe a super small fly is necessary, tenkara anglers hardly ever go any smaller than a size 16 for their fly. The size 16 fly will be handy for those days when a fish is rising to the fly but not taking it, or in waters with a little more pressure and pickier fish. 3 Flies Per Set.
