Yūrakuchō (有楽町) is a business district of Chiyoda, Tokyo, Japan, situated in between the Ginza and Hibiya Park, southeast of the Tokyo Imperial Palace. The district takes its name from Oda Nagamasu (1547-1622), who was also known as Yūraku (有楽). Oda Nagamasu built his mansion here on land granted by Tokugawa Ieyasu near the Sukiya-bashi Gate of Edo Castle. The place name dates from the Meiji period.
