Toilet Zone Lights
There’s nothing worse when you have to get up to pee in the middle of the night and turn on the bathroom light. The light is so blinding that it’s better to leave it off and hope that your aim is right. Most of the time, it’s not, but that’s a problem for your future self to take care of.
That’s not the case in Japan. You can find these glow-in-the-dark strips along the inside of the toilet bowl. They gently illuminate the toilet’s surroundings, so you know where to aim and not make a mess.
