One of my favorite experiences in Japan, Nara Park is home to hundreds of wild sika deer that roam freely and have become accustom to approaching visitors. Locals around the park sell wafer-like cookies to tourists that you can feed to the deer - and some deer have even learned to bow in order to receive a treat. Do be aware that the moment they see or hear food, the deer will swarm to the person who has it. My friend was eating ice cream and a deer literally got desperately up in her face trying to get a bite for himself. The video is pretty hilarious. This place makes for great selfies, but don't forget these are wild animals - be respectful of their space and their land.
