Everybody living more than a couple stops away from the night time destinations knows they have to either go home around midnight, or stick it out until 5am. When and where is the best place to hook up with someone in Tokyo? The cities especially Shibuya, Shinjuku, Ikebukuro, Roppongi, and other major stations are bright and loud with the sound of laughter and lively conversation as people are emptying into the streets from finished nomikais drinking parties , dinner dates, social obligations, and some unlucky overtime shifts.
