Roppongi is a tempting, crazy place. Many expats love or hate Roppongi clubs for its bizarre demographic mix unseen anywhere else in Tokyo.
It's also brimming with punks – really persistent ones, and oddly usually Nigerians – trying to pull you into their clubs.
But it's also possible to have a really memorable night, if you have some Japanese friends to show you around (or you just happen to be down with the more low-brow kind of party).
Or you could wake up not knowing where you are and short a few thousand dollars. And not in a good way.
