Japan’s trains are often overcrowded during the morning and evening rush hours, when millions of people use the trains at once. To get as many people in the trains as possible, train companies employ pushers, who they call oshiya.
Pushers do exactly what their names suggest. They push people into trains. They also have the secondary role of stopping commuters from entering full train cars. Pushing is actually a complicated profession despite how easy the job sounds. Training alone takes as long as six months. Pushers are required to inform commuters before they start pushing and only push gently by the back or shoulder.
They are also required to push with both hands so that they can be balanced, and they must have good footing so that passengers trying to get onto the train won’t push them inside. Becoming a pusher is not a viable career route because it is a part-time job. Pushers only push during the rush hours.
