Kōjimachi

Prior to the arrival of Tokugawa Ieyasu, the area was known as Kōjimura (糀村). The area developed as townspeople settled along the Kōshū Kaidō.

In 1878, the Kōjimachi area became 麹町区 (Kojimachi-ku), a ward of the city of Tokyo. In 1934 and 1938, the addressing system along the Koshu-Kaido was reorganized, creating the 6 chomes subdivision for Kōjimachi that are still used.

In 1947, the Kōjimachi ward was merged with the Kanda ward to form the modern special ward Chiyoda, and the 6 chomes became the Kōjimachi district.

The area centered upon Kōjimachi including the districts of the Banchō area, Kioichō, Hirakawachō and Hayabusachō is sometimes referred as the Kōjimachi area (麹町地区), not to be mistaken with Kōjimachi ward (麹町区).
