Tenkara is an ancient Japanese fly-fishing technique for use on small streams. It is quite similar to dapping. In Tenkara, the angler uses a delicate and sensitive 12' rod, no reel and an ultra light, rod-length line fastened to the end of the rod.
The technique involves a light touch with mastery of patience and rhythm. In essence, it is the purity and simplicity (or lack of encumbering mountains of gear) that puts you in harmony with the fish and the stream. At it's most basic, Tenkara involves a very slow and short casting stroke, but there are many more advanced techniques. Dry flies and certain types of nymphing are well suited for Tenkara.
