Shirasu are said to be particularly selective and difficult to capture in a pattern where they are picky about transparent or small-grained baits such as whitebait, plankton, and nettle. Solid bodies are effective in such situations. Compared to general hollow body hardbait, there is very little diffused reflection, and it has a sense of transparency and unique texture, allowing even selective rockfish to use their mouths.

Adopts a joint structure that produces a lustrous action like softbait even though it is hardbait. When retrieving slowly, WOBBRING action naturally attracts the fish, and when retrieving quickly, the fast-pitched S-shaped action appeals to the fish.

no-sinker rig design allows for slow fall/retrieval. Based on slow retrieval just below the water surface, a variety of lures are possible, such as lift & fall on the surface/shallow that takes advantage of slow fall, and swinging action that reduces travel distance.
