In some elevators in Japan, mostly in department stores, you still can see people working as elevator operators. They just stay all day in the elevator pressing buttons and making sure that the doors open and close in a timely manner; they also announce the floor number each time the elevator stops and check if everybody can leave or enter the elevator at the desired floor. I don’t know if it’s another one of those Japanese “useless jobs” or not, but it seems like a really tiring and not very rewarding job to do if you work as an elevator operator for years.
