Omoide Yokocho is an entertainment district located in the shopping street at the West Exit of Shinjuku Station, and it is characterized by a retro atmosphere that has earned it the name of "the Holy Land of the 'oyaji' (middle-aged men.)" With a wide variety of dining options that include grilled chicken restaurants, izakayas, ramen restaurants, and bars, it is not rare to see white-collar workers start drinking around 5:00 pm in this area.
