How difficult is it to snag a hotel or airbnb in Okinawa?

My husband, siblings, and I are travelling to Japan in October of 2026. We are booking our flights to the mainland and domestic to Okinawa in January as I have found that it is generally the cheapest whenever we book in January-Feb for October/November.

I am wondering how early we should book the Okinawa hotel. I can see on Airbnb that places I have saved have mostly booked up already for the weeks we want to go. Are the hotels the same? Or do most hotels in Okinawa not let you book until 3-6 months in advance? I’ve had trouble finding a straight answer online.

This will determine if I book the accommodation now, in January or a bit later.

Any advice/suggestions are much appreciated.
