Published Oct 29, 2026 — Skin, tongues and lips caught in rotating blades; devices had to be dismantled
On October 29, 2026, Japan's Consumer Affairs Agency (CAA) issued an alert about entrapment injuries caused by electric nail files. Unlike a manual clipper that cuts the nail in one action, these devices shave the nail down gradually with a rotating blade. They are sold under names such as "electric nail clipper" or "electric nail grinder," come in rechargeable and dry-cell versions, and some add a buffing function or an LED light. They are widely available not only at electronics retailers but also through TV shopping and online stores. Two patterns of accidents prompted the alert. The first involves use: the CAA had received multiple reports, mainly from older users, of skin around the nail being drawn into the rotating blade and becoming stuck. The second involves storage: because some models are small, easy to grip and shaped like a toy, children have picked them up, switched them on, and caught their tongue, lips or neck skin in the blade — cases reported by medical institutions. In several of these accidents the trapped tissue could not be freed from the blade, and medical staff or ambulance crews had to take the device apart to remove it. The CAA checked how the products perform and ran reproduction tests simulating soft tissue contacting the rotating blade. Based on those results it has now published safe-use and safe-storage points alongside the actual accident reports, together with an awareness video and poster.
Electric nail files are easy to buy through Japanese online and TV shopping channels, but many come with Japanese-only manuals, so foreign households may not realise the device works by shaving the nail with a rotating blade. Holding the skin in place as you would with a manual clipper is exactly how fingers get caught. In homes with small children, a device left in a drawer or on a table can be mistaken for a toy and put in the mouth. Reported cases include a 3-year-old whose tongue was caught — ambulance crew spent an hour taking the device apart with pliers to free it — a 2-year-old with an injury reaching the subcutaneous tissue of the lip, and a 4-year-old who held it against the neck like a shaver, caught the skin and was hospitalised for observation. If an accident happens, calling an ambulance and explaining the situation at the hospital will involve Japanese. Keeping the product box or a photo of the device on hand makes it much faster to convey what happened.
