We researched and perfected an underwater posture that allows the wary wild sweetfish to chase without making them feel uncomfortable. Position horizontally so as not to make the sweetfish feel uncomfortable. The underwater action doesn't have a strong appeal, but instead shows a sweetfish drifting in the current. The Harris stopper is installed at the position of the fat fin. Now you can use long Harris hooks and large size hooks, making it possible to hook sweetfish that are slow to catch. This type of fishing, where you aim for sweetfish by crawling along the riverbed, requires a strong lip. Therefore, unlike conventional lures, Nagaayu uses a resin lip that is resistant to damage. Because it is made of resin material, the sound when the lip hits the stone is also reduced. Yellow Lip makes it easy for anglers to see the lure position, so they can aim at the desired point. *Please be sure to follow the rules when using it. ●Before going fishing, be sure to check the rules and recreational fishing permit details of each local fishery cooperative, and purchase a recreational fishing permit from each fishery cooperative. ●Fishing fields, fishing seasons, recreational fishing fees, tackle, hook regulations, etc. differ for each fishing cooperative. ●If you live in a river where there are no recreational fishing permits or fishing regulations, be sure to follow local regulations. ●Do not use fishing gear in areas where the use of fishing gear is prohibited.
