Seven years ago I took ferries between Japan and Korea about six times, and I'm looking at taking the ferry again.
I seem to recall that even when paying for the ferry ticket in cash that there is also some fee or tax that can only be paid in cash. I remember getting caught out by this once or twice and having to find an ATM at the last minute.
In 2019, when going in the direction from Japan to Korea, how much are these fees/taxes that I'll only be able to pay in JPY, so I can keep aside that amount when spending my last Japanese money?
