Nagatachō in the context of "Japanese Diet"

The prime minister of Japan (内閣総理大臣, Naikaku Sōri Daijin; Japanese pronunciation: [naꜜi.ka.kɯ | soː.ɾʲi daꜜi.dʑiɴ]) is the head of government of Japan. The prime minister chairs the Cabinet of Japan and has the ability to select and dismiss its ministers of state. The prime minister also serves as the commander-in-chief of the Japan Self Defence Forces. The incumbent prime minister, Sanae Takaichi, took office on 21 October 2025; she is the first woman to serve as either president of the Liberal Democratic Party or prime minister.

The National Diet (parliament) nominates the prime minister from among its members (typically from among the members of the House of Representatives). They are then formally appointed by the emperor. The prime minister must retain the confidence of the House of Representatives to remain in office. The prime minister lives and works at the Naikaku Sōri Daijin Kantei (Prime Minister's Official Residence) in Nagatachō, Chiyoda, Tokyo, close to the National Diet Building.

The National Diet (国会, Kokkai; Japanese pronunciation: [kok̚.kai]) is the national legislature of Japan. It is composed of a lower house, called the House of Representatives (衆議院, Shūgiin), and an upper house, the House of Councillors (参議院, Sangiin). Both houses are directly elected under a parallel voting system. In addition to passing laws, the Diet is formally responsible for nominating the prime minister. The Diet was first established as the Imperial Diet in 1890 under the Meiji Constitution, and took its current form in 1947 upon the adoption of the post-war constitution. Both houses meet in the National Diet Building (国会議事堂, Kokkai-gijidō) in Nagatachō, Chiyoda, Tokyo.

The Naikaku Sōri Daijin Kantei (内閣総理大臣官邸) or Prime Minister's Office is the official workplace of the Prime Minister of Japan. It is commonly referred to as Shushō Kantei (首相官邸), or simply Kantei (官邸). Unlike many other famous offices or palaces of world leaders, such as the Kremlin in Russia or the White House in the United States, the Japanese Prime Minister's Office has no nickname. Naikaku Sōri Daijin Kantei literally translates to "Prime Minister's Office" in English.

Located at 2-3-1 Nagata-chō, Chiyoda-ku, Tokyo 100–8968, it is diagonally adjacent to the National Diet Building. The term Kantei is used as a metonym for the office of the Prime Minister of Japan and for the Prime Minister's advisors and administration in general.
