JCMU Story:
Well, as crazy as it sounds, the fondest memories from the time in Japan was hanging out with the rest of the students at the university. Playing Guilty Gear until the wee hours of the morning, being forced to watch about fifty episodes of Full Metal Alchemist, and making fun of each other non-stop for the stupid bike helmets was fun.
The classes themselves were also great; I can't ever get the phrase "pinch hitta" out of my head. The Friday activities we're also harrowing if not fun in their own right; being paraded in front of a large elementary school of several hundred kids was something I won't forget.
Also, if you go to Japan, make sure you don't leave your bike in the bike parking garage after hours. I'm just sayin'.
