Miyako Island is a beautiful island in Okinawa. Although it`s a little more expensive to go here than Ishigaki (due to the flights), it`s another great place to check out! You can rent a car for as low as 4000 yen per day! So depending on where your hotel is, it`s a good thing to consider.
Go Diving / Snorkeling
Dive in the beautiful ocean and swim with the fish and look at the beautiful corals!
