I recently spent a few weeks in Japan visiting some of my family who is in the Military. That country is amazing. I mostly stayed around the Yokouska/Yokohama area, and had a wonderful time. Only regret is not climbing Fuji, but seeing it from the base was incredible.
A few years ago I also volunteered in Lima, Peru for a couple of weeks. I mostly worked out of a school in the district of Villa El Salvador where I painted a few school rooms, and sat in on some classes and helped out the kids and shit. Also, I broke edge in Peru which was awesome. The rest of my mornings in Peru were miserable, and now I really love drinking.
