I made a reservation in advance for the car ferry that runs between Takamatsu Port and Tonosho Port on Shodoshima Island. On the day of boarding, I presented my voucher and vehicle registration certificate at the counter to exchange it for a ticket. The process was smooth. If you have passengers, you will need to make a separate reservation for them. If you are renting a car and are unsure of the appropriate vehicle classification, it seems possible to pay the difference locally. As of November 2025, local counters only accept cash payments, so I think it's a benefit to prepaying through kkday to have the option of paying by credit card or other means.
You can take most routes, and you don't need to buy a limited express ticket for the limited express. There are plenty of unreserved seats, so you'll almost never run out of seats.
Communication was smooth, the driver was very nice, drove very smoothly, and the car was very clean.
