Traaaains! Ugnh!
Quicky: while in Ōsaka, I took a train from Fukushima eki (station) to Nishikujo eki. There I transferred to a non-JR line, so I had to buy a regular ticket. After transferring and getting off at Kujo eki, the gate wouldn’t let me through. The puzzled expression on my face, quickly drew the attention of an employee. He indicated that I had to pay ¥60 (about €0.48) more to complete the trip. Woops. Sometimes freedom comes cheaply. xD
