Recent arrests include a 38-year-old man who hid the miniature cameras in clothes hangers in girls’ changing rooms at a high school in Kobe

Increasingly sophisticated technology has made these cameras, ostensibly for surveillance, smaller and harder to detect. Not only are they tiny enough to tuck away in small corners of bathrooms and changing rooms, they can also be disguised as buttons, clocks, pens and – in a recent case – clothes hangers.

In May last year, a 38-year-old man was arrested and later jailed after police found several spy cameras hidden in hangers in girls’ changing rooms at a high school in Kobe, western Japan, Kyodo news agency reported.
