First you can buy ticket directly from the machines in front of station. What you have to do is to decide you destination by finding your line or route then you can trace your desire station along that line. Below the station’s name listed the price that you have to pay. This price is an input parameter to the machines. If you can’t find your station, because it writes in kanji…don’t worry. Just select the smallest price but you have to re-adjust your ticket after your stop at your desire station. You can find readjustment machine before leave the exit gate or ask officer on duty.
Another option is you can use electronic card or hand phone. For electronic card you have to charge it or at least you have enough balance in your e-card. You have to touch your card on screening point on the entrance gate. Your balance will be reduced after your leave your station.
This is the example how smart monkey(Pan-kun) and James go to the nearest/closest station by using ticket. Funny…enjoy.
