Onahole

Definition

Onahole (オナホール, from "onanii" meaning masturbation + "hole") is the Japanese term for male masturbation sleeves, handheld strokers with textured internal canals made from soft, skin-like materials. While functionally similar to a Fleshlight, onaholes represent a distinct product tradition from Japan that emphasizes different design priorities: complex internal textures, compact sizes, softer materials, and often character-themed or anime-inspired aesthetics.

Japanese manufacturers like Tenga, TOYSHEART, and Magic Eyes produce onaholes with internal canal designs that can be remarkably complex (spiral ridges, vacuum chambers, multi-layered textures, and anatomically varied passages. The form factor tends to be smaller and more discreet than Western equivalents, with many designed for single use or limited reuse. The category includes everything from simple, inexpensive disposables to premium, elaborately engineered devices. For gooners running extended sessions, onaholes offer a different sensation profile from Western strokers) generally softer material, tighter fit, and more elaborate internal stimulation patterns. are beginning to integrate onahole-style designs with interactive technology.
