National Diet Building
At the tip of Musashino plateau, Chiyoda is located at the very heart of former Tokyo City in eastern mainland Tokyo. The central area of the ward is furthermore occupied by the Imperial Palace. The east side of the ward, bordering Chūō, is the location of Tokyo Station. The south side, bordering Minato, encompasses Hibiya Park and the National Diet Building. It is almost exclusively occupied by administrations and agencies. The west and northwest are primarily upper class residential; the Yasukuni Shrine is also there. The "high lantern" of Kudanzaka slope was not originally built as a lighthouse, but was built as a lantern for the Shrine. Originally steep and with steps, the slope was considerably softened during remediation after the Kanto earthquake. To the north and northeast of the ward are several residential neighborhoods and the Akihabara commercial district.
