last trains in tokyo leave around 1215, if i remember right. i never actualy go the last train but i do recall jumping on one from shibuya at 1215ish. might have been 12.

anyway the trains start running at 5am.

you really wanna be going to shibuya, ikebukuro, daikanyama and nakameguro instead of roppongi for local flavour though. roppongi will be just like any other club/bar in any other city anywhere in the world, but i guess it really depends on what youre after.
