Need to rent a car without credit card!

Hello everyone,

I'm (based in Netherlands) coming to Okinawa in November, and i've red that you really do need a car to get around the island. The problem is though, that the person i'm travelling with has a international drivers license, but can't apply for a credit card, and i don't have a drivers license at all.

So my question is; is there any way to rent a car without a credit card? I do have a credit card, but i guess the rental contract requires the credit card of the person renting the car?

I hope anyone can inform me on this matter and has some tips !

Thanks in advance 🙂
