“What's going on?”
I am sure that I am an exception, but I didn't like Akihabara much, even I grew up with Manga and Anime.
For me it was almost impossible to get a sense of direction. If you know this area and shops well, I am sure it's heaven. As a tourist just having a look it was too much of everthing.
After 1 hour we just left and I started to get a headache. Little culture shock in a way.
