Chiyoda (千代田区, Chiyoda-ku) is a special ward located in central Tokyo, Japan. It is known as Chiyoda City in English. It was formed in 1947 as a merger of Kanda and Kōjimachi wards following Tokyo City's transformation into Tokyo Metropolis. The modern Chiyoda ward exhibits contrasting Shitamachi and Yamanote geographical and cultural division. The Kanda area is in the core of Shitamachi, the original commercial center of Edo-Tokyo. On the other hand, the western part of the Kōjimachi area typically represents a Yamanote district.
