Nagaayu Deep lets you explore deep waters that you couldn't reach on Nagaayu 110F. Even in situations where it is difficult to trace near the bottom with a regular short-trip ayu lure, such as deep tuna fishing grounds with slow currents, you can reliably get to the bottom with Nagaayu DEEP. Even if you are deep in the area around the bottom stone, which is the key point for territorial Ayu, you can definitely make an appeal. *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 there is someone in front of you, please be sure to keep a sufficient distance. Also, avoid unnecessary long throws and use at a point where you can definitely collect it. ●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.
