1. The Pioneer of the High-Density “Sinking Bug” Soft-Plastic

In the history of bass fishing in Japan, bug-style soft baits have existed for decades. Traditionally, they were closely associated with smallmouth bass fishing or summer sight-fishing, and were widely viewed as lures meant to float on the surface and tempt bass from above.

That fixed idea was completely overturned by Haruhiko Murakami—the brilliant mind behind the Neko Rig—who popularized the concept of sending “bugs” down into the bottom zone.

Before this breakthrough, high-density, weightless soft-plastics designed to sink were typically simple stick-shaped baits, such as the Senko or improvised sweet-potato-style baits made by tearing the tail off a grub. Murakami introduced a radical evolution by adding “legs,” merging lifelike presence with functional performance.

Today, the “sinking bug” category has countless followers, but the original SHIZUMI MUSHI has become a staple among Japanese anglers, consistently ranking at the top of lure popularity charts in Japanese bass fishing magazines.

2. Legs That Vibrate on the Fall and Retrieve—Controlling Travel Distance for Precise Targeting

The defining feature of the SHIZUMI MUSHI is the set of legs on both sides of the body. These are not merely visual imitations, but elements engineered to serve two critical purposes.

First is the control of travel distance combined with the generation of subtle vibration. During the fall or while dragging along the bottom, the legs constantly quiver as they catch water, creating fine, high-frequency vibrations. These micro water disturbances transmit the signature of a small, struggling creature directly to a bass’s lateral line. At the same time, the legs function as an underwater brake, preventing unnecessary movement and allowing the lure to stay in the strike zone longer for true pinpoint presentations.

3. High Density Creates a Natural, Uninterrupted Falling Posture

The ultra–high-density material used in the SHIZUMI MUSHI is not intended simply to increase casting distance. Murakami’s primary focus was achieving a natural fall.

Lightweight soft-plastics are easily affected by line weight and wind resistance, often resulting in distorted or unnatural fall angles. In contrast, the SHIZUMI MUSHI’s substantial mass pulls the line itself down into the water, allowing the bait to sink in a nearly vertical posture. Free from interference caused by line tension, the lure appears to fall of its own will—an exposed, defenseless descent that convinces pressured big bass to commit. Casting distance is merely a byproduct of this physical necessity.

4. The Ultimate Cover Tool: Backslide-Compatible Setup

Beyond standard straight-hook bottom presentations, the SHIZUMI MUSHI truly shines when used for backsliding presentations that penetrate the deepest parts of cover.

Its rear-weighted body design not only stabilizes the bait in flight for improved casting accuracy, but also generates forward-sliding momentum after splashdown, pulling the lure deeper beneath overhangs and cover. By inserting a nail weight diagonally into the belly, the center of gravity is lowered and stabilized even further. This dramatically increases slide distance, allowing anglers to reach spots—deep under overhangs or into complex cover bases—that are physically unreachable with conventional light rigs.

5. Dead-End Situations: Choosing Between Sinking Bug and Floating Bug

The water surface and the bottom represent ultimate “dead ends” where baitfish have nowhere left to escape. Bass instinctively use these boundaries to corner and feed efficiently.

When bass are aware of the surface “ceiling,” a floating bug-style bait: BiBiBi CHU is the better choice, drawing fish out at the surface boundary where escape routes are limited.

When bass are keyed to the bottom “floor,” the SHIZUMI MUSHI becomes the tool of choice. By sinking both the lure and the line completely, it minimizes the presence of the line and triggers the bass’s final pursuit instinct right along the bottom.
