I bought a commuter pass of the train for 24,190 yen ($241.90 €186.08) at a ticket vending machine in the station. It is a 6 months-period pass, it is valid from July to next January. The average cost of a commuter pass is 100,000 yen ($1,000.00 €769.23) in Tokyo. It is 4 times expensive of mine. I live in a closer town from the office. The commuter pass is an IC card. If you add an extra money deposit on the pass, you can use it as an electronic money.
