On a serious note, Akiba is pretty chill. I did some of this footage a couple of weeks back, but I tend to go there about once a week to see what the latest deals are. Surprisingly, Akiba is really small in comparison to what people may think. You've got the major strip with the flashing lights and a couple more lit up side streets, but the majority of it is just major office buildings.
