Electric Town is the name of the area for which Akihabara is famous.
Electronic goods shops are there side by side, often exposing the same kind of products with the same prices. You can find lots of shopping malls devoted only to electronic, as well as small booths exposing a huge amount of mobile phones or cameras like they were necklaces for tourists.
You can hear everywhere speakers with microphone promoting their shops' new items or special offers. As everywhere in Tokyo center, your ears will never have a rest as long as you stay outside on the streets.
