I travelled to Japan once last year, I had so much fun I'm looking to go back. Looking for a travel buddy/group to go for about 2 weeks this fall.

I really liked Osaka and had a few things I wanted to do in Kyoto that I didn't get around to, so I'll definitely want to go to those cities. 

I'm also interested in going to Kyuushuu/Shikkoku/Okinawa, as well as just the southern parts of Honshuu, since I didn't get around to any of those last time, but doing all of that in 2 weeks is probably excessive, so we'd have to cut down on some of it, depending on what looks the most interesting. I've also got a few things I never did while I was in Tokyo that I wanted to do.
