Chiyoda, Tokyo
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. Chiyoda consists of the Imperial Palace and a surrounding radius of about a kilometer. As of June 2020, the ward has an estimated population of 66,575, and a population density of 5,709  people per km², making it by far the least populated of the special wards. The total area is 11.66 km², of which the Imperial Palace, Hibiya Park, National Museum of Modern Art, and Yasukuni Shrine take up approximately 2.6 km², or 22% of the total area. Chiyoda is an economical powerhouse, the small area East of the palace in the districts of Otemachi, Marunouchi and Yurakucho (colloquially "Daimaruyu") houses the headquarters of 19 Fortune 500 companies, is the source of roughly 10% of the combined revenue of all Japanese companies and produced in 2017 the equivalent of around 1/4th of  the GDP of the country. With a day population of around 850,000, its day/night population ratio is by very far the highest of all municipalities in Japan. Chiyoda is also the political center of the country, Chiyoda, literally meaning "field of a thousand generations", inherited the name from the Chiyoda Castle (the other name for Edo Castle, today's Imperial Palace). With the seat of the Emperor in the Imperial Palace at the ward's center, many government institutions, such as the National Diet, the Prime Minister's Official Residence, the Supreme Court, ministries, and agencies are also located  in Chiyoda, as are Tokyo landmarks such as Tokyo Station, Yasukuni Shrine and the Budokan. The neighborhood Akihabara is also located in Chiyoda, as are twenty embassies and consulates. History. Chiyoda has been a site of a number of historical events. Geography. 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. Politics and government. Local government. Chiyoda is run by a directly elected mayor and a city assembly of  25 elected members. The current mayor is Takaaki Higuchi. Metropolitan representation.

Some of the districts in Chiyoda are actually not inhabited, either  because they are parks (Hibiya Koen), because they consist only of office buildings (Otemachi or Marunouchi), and/or because they are extremely small. The area on the eastern side of Akihabara Station is the location of several districts that cover at most a few buildings. Kanda-Hanaokachō is, for example, limited to the Akihabara Station and the Yodobashi Camera department store. Understanding the address system in the Kanda area can be particularly troublesome for non-locals. The list below consists of the many smaller neighborhoods of the Kanda area, for which a modernization of the addressing system has not been enforced  yet except Kanda-Sarugakuchō and Kanda-Misakichō.
