Piss Alley has been rebranded and renamed in recent years as “Memory Lane” for obvious reasons. It is a long-standing favorite drinking and snacking area (mostly drinking) adjacent to Shinjuku Station, designed for a quick one for the road for commuters on the way home. A remnant of the bygone days, Piss Alley features small bars, cheek-by-jowl in a narrow lane. Its nickname is said to have come about because drunks used to take a leak in the alley back in the good old days when that sort of behavior was overlooked. It is a reminder that the surrounding shiny skyscrapers were not always there, and that Japan even today has these back-alley joints for a quick drink & snack. These days public rest rooms are provided to prevent the public from being offended. And to contain the smell.
