ELI5: Explain Like I'm 5

Sound Princess

The Sound Princess is a very special feature in some Japanese pedestrian crossings, designed to help people with visual impairments cross the road safely. The Sound Princess is like a little box that plays a very special sound when someone presses a button to indicate they want to cross the road. The sound is like a friendly voice that says "it's safe to cross the road now." This helps people who cannot see the traffic lights or the road, know when it is safe to walk across. So, the Sound Princess helps people who have difficulty seeing to cross the road safely, just like a princess who helps people wherever she can.
