Also known as Akiba. Akihabara is located in the Chiyo ward of Tokyo. It is otaku heaven without a doubt, tall buildings with humangous anime posters, lots of shops selling various electronic, computer, console, anime, merchandise, manga and of course Gundam Café...
Speaking of Cafes, there are several maid cafes too.
