The KAKU-MEIKI MEDIUM Mimizu 400 Soft (KAKU-MEIKI MEDIUM ミミズ400【SOFT】) is Peach Toys’ answer to the “thousand earthworms” legend: a handheld onahole that packs an unusually high density of ridges into a compact, 410 g body. Instead of a few scattered textures, the tunnel is lined with hundreds of small, closely spaced vertical folds that create a continuous, wriggling sensation from entrance to end.
This SOFT version uses a single-layer, bouncy TPE formulation tuned for a gentler, more forgiving feel than the STD variant. The tunnel is closed-ended and 13 cm deep, with a slightly firmer entrance that helps maintain structure during use. At 16.5 cm overall length and 7.5 cm in width and height, it’s easy to hold and manoeuvre with one hand, yet substantial enough to feel solid during slower, more deliberate strokes.
The Mimizu 400 Soft is best suited to users who enjoy dense, all-over ridge stimulation without aggressive pressure points, and who prefer a softer material that emphasises enveloping texture over tight suction. Cleaning is straightforward thanks to the single closed tunnel, though the high ridge count means thorough rinsing and drying are important.
