Pictured on the left is a wall plate of five Japanese light switches. They’re always mounted to switch horizontally (as opposed to vertically in the US). The little oval mark is the “on” position, which always seems to be on the right. The bottom two switches are for vent fans (I took this picture in a commercial kitchen), which when switched on, are backlit by a red light.
Also interesting is that most switches are outside of the room they’re switching, so you have to turn the light on before you enter a room, or you’ll have to go back out if you forget.
