Adachi-ku hit the headlines last year when ward officials tried to curb teen vandalism in a local park by installing the Mosquito, a device which emits irritating high-frequency tones that are inaudible to older people. Toymaker Epoch puts the same technology to ingenious use in this gadget that’s tailor-made for exposing frauds on gokon group dates. Think the guy sitting across from you looks at least ten years older than he claims to be? Simply flip the switch to the relevant setting—teens, 20s, 30s or 40s—and give him a burst of age-appropriate aural irritation. That should clear things up in no time.
Toshibareru, ¥924. Available from most toy stores.
