The train system is highly efficient in Japan but it can be confusing and daunting at times especially when you look at a transit map. You’re not alone there though, even the locals sometimes struggle with knowing exactly how much a fare will cost at their destination. Every station has these handy Fare Adjustment machines where you insert your ticket at your destination and it tells you if you’re short on the fare and need to insert more coins to complete your trip. The machine then issues a new ticket with the correct fare and you can exit through the turnstiles. Very handy, right?
Here’s a video of me illustrating how to use the machines and what you need to look out for.
