Kōjimachi

Kōjimachi is a neighborhood in Chiyoda, Tokyo. Prior to the arrival of Tokugawa Ieyasu, it was known as Kōjimura. The area developed as townspeople settled along the Kōshū Kaidō. In 1878 Kōjimachi became a ward in the city of Tokyo. In 1947, it was merged with Kanda to form the modern special ward Chiyoda.
