Japan trip

I'm going to Japan next month.  August 9th - 19th.  The main purpose of this trip is to go to Yakushima.  But I will also be going to Osaka and Kyoto.  This will be my 6th trip to Japan.  Living in Korea, I am so close to Japan, but this will be my first time to go there since I came to Korea.  I'll be taking a boat to Fukuoka from Busan and flying back to Seoul from Osaka.
