Fly-fishing and lure fishing have been positioned as sports deliberately different from the traditional Japanese fishing-style. In the case of lure fishing, casting is the element which anglers must master in order to cast a lure at an appropriate position. Lure fishing constitutes various elements, for example, casting, reeling, hooking and landing, but the importance that casting holds is extremely large. This study uses experimental and computational analysis to investigate the dynamic behavior of lure casting. The casting process and the timing of the line leaves are important for the proper presentation of lure. Moreover, the shape of a rod before the lure released is important for a long cast or controlled cast. However, it is difficult to grasp the phenomenon or to make a numerical model. Therefore, the most suitable casting method will be clarified from the viewpoint of sports engineering and human dynamics. In this paper, the system of rod and lure is modeled, and the behavior of the rod and the flying distance of a lure are calculated in the case that line tension is considered. The difference of the behavior and flying distance with line tension is investigated. And suitable timing that angler releases the line is clarified. Moreover, hang length of lure is investigated and proper length is obtained.
