I will be staying in a guest house in Naha City, the capital of Okinawa prefecture in Japan, and was considering a day trip to Taketomi Island
Taketomi is one of the so-called "Isolated Island" of the Japanese Yaeyama islands. So far, I got that the main way to go there is:
go to Ishigaki Island by plane (50 min)
travel to the ferry terminal (40 min)
take a 10-min ferry to Taketomi.
Including waiting time, I guess it takes 2h30 at most. This seems realistic. But all day trip tours I can find starts from Ishigaki, so I am starting to think that the trip is not that easy to do in one day.
Is it possible to do a one day trip to Taketomi Island from Naha City? Waking up really early/going back really late is not an issue.
If so, are there guided tour departing from Naha City?
If I travel alone, is it fine to buy the ferry and/or plane tickets on the spot? As I am not sure at what time I would finish my day trip, I am not sure how to make a reservation.
