A Seductive Soft-Plastic That Undulates from Head to Tail with Its Multi-Slit Body
1. A Deep Multi-Slit Body That Makes the Entire Lure Undulate

The defining feature of the Katakuchi Worm YAVAKUNE is its deeply and precisely cut multi-slit body. Rather than the stiff “tail-only kicking” action common in many soft-plastics, this lure was designed by Haruhiko Murakami to replicate how a real baitfish swims—flexing its spine and muscles to move the entire body.
Even subtle water resistance causes each section of the body to flex independently, creating a smooth, full-body undulation from head to tail. This isn’t just about visual realism. Murakami focused on reproducing the quality of water displacement generated by living baitfish. The result is a biologically inspired design that produces a soft, natural vibration bass perceive through both sight and their lateral line.
2. Not Just a Roll — A “Cascading Undulation Roll” That Sets It Apart

YAVAKUNE truly shines on a mid-strolling retrieve. As the jig head rolls, the body follows with a slight delay, creating a cascading undulation from head to tail. Instead of a flat, side-to-side roll, the lure twists progressively down its body, producing a far more lifelike presence underwater.
While many mid-strolling soft plastics rely on a predictable rolling action, YAVAKUNE adds irregular, glossy movement to the mix. It’s built for fish that follow but hesitate. That subtle, delayed body response often provides the final trigger needed to convert a looker into a biter.
3. Pair It with the AK Chatter for a Seductive Bladed-swim-jig Profile
The AK Chatter was engineered to transmit tight, high-frequency blade vibration through the entire trailer. That’s exactly why YAVAKUNE is such a natural match.
Because its body flexes from head to tail, the blade’s vibration travels seamlessly through the multi-slit design. The result is a tight yet fluid action that resembles a real baitfish struggling under pressure—subtle, refined, and alive. Instead of simply adding bulk, YAVAKUNE enhances the chatterbait with movement quality that feels organic and convincing.
4. Also Excellent for “Piku-Piku” Topwater Rigging
A weedless dropshot hook placed near the center of the body, combined with a nail weight inserted toward the tail for rear balance, creates an effective “piku-piku” surface setup.
With just light line twitches, the entire body continues to undulate on its own, producing delicate surface ripples.

Because the action doesn’t completely die on the pause, it excels in situations where you need to keep the lure in place and let fish study it—ideal for sight fishing or pressured shallow water.
