Roppongi, located in Minato Ward, is one of Tokyo's top entertainment districts which is active 24 hours. In recent years, large business and commercial complexes such as Roppongi Hills and Tokyo Midtown, and the National Art Center were built to add attributes to the town. Many foreign diplomatic missions and international firms locate here and a large number of restaurants run their businesses for foreigners. On weekdays during the day time the streets are usually occupied by office workers, but after dark the same town turns into a sole entertainment center packed with people of all races.
