Tokyo,, any suggestions?

Im gona be in Tokyo for a week for work, but hopefully ill have a few days to check out some sights-
Anybody got any insights into must see attractions - design districts / or cool live music areas / crazy cool stuff / anything really?

Cheers

Lucky you.

I think Plus Minus Zero shop and Tokyu Hands are must sees!

Also Akihabara electronics district!

Have fun.
