Okinawa – OKA processing time

Hello! I’m planning to fly from KIX to OKA and then travel by ferry to Zamami.

I am supposed to land at OKA at 2:05pm and the last ferry to Zamami is 3:00pm.

Will there be enough time to get to the ferry from OKA? It’s a short drive, but does anyone have a general processing time for exiting the airport (eg are there customs / other process?)

Big thank you!
