Akihabara, or Akiba in slang, is Tokyo's "Electric Town" on the eastern side of the central Chiyoda ward. The area houses thousands of shops selling every technological gadget you can imagine, from computers to gaming consoles and vacuums to DVDs, at reasonable prices. 

This area is also known as the "Gamer's Mecca" and has become strongly identified with anime/manga subculture, with the legions of otaku geeks traipsing down on weekends known as Akiba-kei.

Akihabara is all about shopping. One of its few sights, the Transportation Museum, moved to Saitama as the Railway Museum.
