This is a fishing rig for Ayu fishing. It is a set of 9 rigs, tied with W butterfly hooks (Yanagi or Yajima size 7) in 3 stages. It can be used for friend fishing, Ayu lures, and Ayu ing. Compared to anchor hooks, butterfly hooks have fewer snags, and even when the Ayu's scales harden and they start kicking the hooks, the sharp points firmly embed themselves in the fish, allowing for quick bait changes. Unlike aチラシ仕掛け (chirashi rig), this rig doubles the coverage area, making it possible to catch and hold Ayu faster than aチラシ仕掛け. The 3-stage setup extends the reach of the hooks, making it effective for playful Ayu and schooling Ayu.
