Hibiya (日比谷) is a colloquial name for a neighborhood of Chiyoda Ward in Tokyo. The area along Hibiya Street (National Route 1) from Yūrakuchō to Uchisaiwaichō is generally considered Hibiya district. Administratively, it is part of the Yūrakuchō district. There is no actual administrative district in Chiyoda called "Hibiya" but the name is used in some local place names such as Hibiya Park and Hibiya Station (administratively in Yūrakuchō). Hibiya was part of the old Kōjimachi ward in Tokyo City, before it was transformed into a metropolis.

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. 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 Independent Administrative Institution National Archives of Japan (独立行政法人国立公文書館, Dokuritsu Gyosei Hojin Kokuritsu Kōbunshokan) preserve Japanese government documents and historical records and make them available to the public. Although Japan's reverence for its unique history and art is well documented and illustrated by collections of art and documents, there is almost no archivist tradition. Before the creation of the National Archives, there was a scarcity of available public documents which preserve "grey-area" records, such as internal sources to show a process which informs the formation of a specific policy or the proceedings of various committee meetings.In accordance with the National Archives Law No.79 (1999), the core function of preserving "government documents and records of importance as historical materials" includes all material relating to (1) decision-making on important items of national policies, and (2) processes of deliberation, discussion, or consultation prior to reaching any decision-making, and the process of enforcing policies based on decisions made. The transfer of what are deemed historically important materials from the various ministries and agencies is carried out on a regular basis in accordance with the Transfer Plan prepared and revised by the Prime Minister for each fiscal year. Preservation, restoration cataloging, microfilming and digitization are all important aspects of the archive's responsibilities. However, the National Archives is in the process of becoming something more than simply a historical repository, because it is also a complex of structures, processes, and epistemologies which are situated at a critical point of the intersection between scholarship, cultural practices, politics, and technologies.
