Cheap sashimi at the public market was the favourite part of okinawa. I don't really do much shopping but there's the shopping street. Don't expect it to be happening like Osaka or Tokyo la.

Quite nice to drive around the island, speed limit around 50kmh only. Easy drive. Most tourist spots parking also free and easy to find (maybe not summer holiday time). I wanna go back there next time for the other smaller islands and for diving.

fly to osaka, then peach
or taipei then straight okinawa...

Diving are not at Okinawa side.  have to go Yonaguni
