Travelling to Tokyo

Hi all

I will be travelling to Tokyo on 19th April till 22nd for a short holiday, can anyone suggest any fun things to do at night? Do we have any pub crawls or something similar which I can join?

Thanks in advance for your help :-)

Shibuya and roppongi would be very interesting places to go for sure :) a lot of bars! Shinjuku (kabuki cho area) will be good place for bars as well!  Most ppl go clubbing in roppongi or shibuya :) hope you enjoy crazy tokyo!

Sky tree! never been, but a lot of people recommend!
