Three weeks- bulk of time in Osaka/Kyoto, some in Tokyo, also want to hit a southern island. My big questions surround hitting yakushima and/or Okinawa. If we are departing from the Osaka area, is flying or ferrying more reasonable? What about between the two islands? Is it worth hitting both or should we concentrate our time (and how much?) on one? We are nature and food oriented people with an interest in traditional art and would also be happy to hear recommendations for the best museums/gardens etc in your opinion, in any of the areas mentioned above. It will be sept/oct I think.
Also, is it crazy to stop in Hawaii for a couple days on the way back if we fly west coast? We are from Ohio, flew out of ny last time (did one week Tokyo/Kyoto/koyasan- koyasan was absolutely fantastic, loved okunoin)
Ty!
