Car rental

me n my buddy are going to okinawa in april, and wed like to rent a car, flights are april 8 at 10:15, and outgoing april 16th at 11am, so wed like to rent something like 8th 12:00 till 16th 8am (ots says you should drop off 3h before flight), were going to north of okinawa fo 5 days, and then south for 3.

of course wed like to come through cheap, but also kinda worry free, were from europe so chances of an accident are a bit higher (from right-side road to left standard).

I know of OTS, it comes down to 270eur (50.000yen), but i found some klook offers for sub 200eur, but from some "24h rent car" and similar. i also checked tocoo, and its super cheap, but the cost of insurance is then x2 the price, so it comes to 40k+yen.

could anyone advise me on this topic? ive never rented a car, and i have a really bad experience of trying to rent one in madrid, where they almost scammed me for 150eur, because they dont accept revolut.

other than that, im a pretty solid driver, 25m, 200k km+ mileage.

also trip advices and suggestions are welcome, wed like to go snorkling and such.
