If you live in Japan chances are you have one of these things pictured above attached to your front door. These U-shaped door latches provide an extra lock to your door but also allow you to prop it open to let a cool breeze through your home on a sweltering summer day.
Many Japanese people while sleeping or napping rely on these simple devices to safely crack their doors for comfort, but probably shouldn’t. As we will soon show you, these latches are actually about as secure as a stick of warm butter. In fact, in a demonstration video uploaded to YouTube, you’ll see that even the most amateur of criminals can bypass them in seconds.
