My daughter uses train to go to her school. It is 10 minutes ride to the school by rapid service. She bought a six-month student commuter pass for 12,710 yen ($107.71 €97.77). It is a student discount price, and valid until October. This cost consists of the train fare and the deposit money (500 yen). At the first purchase, we have to pay the deposit money. From next time, we do not have to pay it. The fare price varies depending on the distance traveled. Long distance travel requires the higher price.
The standard pass costs 35,590 yen for the same route, almost three times of the student pass.
Here is a sample of train pass.
