Advice on our honeymoon trip in late October

Hello! Currently planning for a 9-day honeymoon trip in Okinawa around the last 2 weeks of October. While I did my research, hoping you guys are kind enough to patiently answer some of my questions.

  1. We’re from a tropical country, so ideally we want weather that’s not too hot and but also not too cold for a quick swim in the ocean. We prefer not sweating and enjoying our strolls. Is late October a good time for that balance? Or would another time be better? We haven’t booked flights yet so we’re flexible.

  2. We’re planning to rent a car, but we’re also considering renting a motorcycle for some days. Is motorcycling enjoyable in Okinawa in October, or is rain frequent enough to make it inconvenient?

  3. We want to have 1-2 hotels only. Which location do you guys recommend? Is Onna good? Our itinerary is mostly nature and chill pacing only. We’ve been to mainland Japan several times already so we’re not that interested in city sightseeing.

Thanks in advance! Any suggestions are appreciated!
