A friend of mine reserved a seat by phone on the Nori bus return Takayama-Shirakawago. His account was when he was at Takayama, he bought the return tickets from the Nori bus ticket-vending machine at the terminal. However he nearly could not get on the bus as the driver nearly refused to acknowledge his reservation; the other passengers got "reserved ticket" not vending machine tickets.
Has anyone done any reservations on the Nori bus? If so, where exactly or how do one gets the reserved bus tickets?
