How to pay for the Kurobe Gorge Railway from Kurobe Unazukionsen Station to Keyakidaira and return to Kurobe Unazukionsen Station on the same day.

Cash for the ticket between Kurobe Unazukionsen Station and Unazuki Onsen.
The Kurobe Gorge Railway can be resrved online in advance and paid by credit card. I can't confirm if credit cards can be used to pay for same-day tickets purchased at the station.

Note that through September 30, the railway will not be running all the way to Keyakidaira this year due to a damaged bridge!
