I actually went to Akihabara more than once during this trip. Akihabara is also known as Electric Town and is a major shopping area for electronic and otaku goods of all kinds. Most of the Mac stores are also in that part of the town, while the Apple Store is in Ginza.
I bought an electronic dictionary and a talking clock here. My Japanese teacher has one which announces the time in Japanese language. I wanted one too!
On Sunday, the big street was blocked for car traffic. Space was definitely not an issue on that day, although most people still preferred walking on the sidewalk.
