Cabinet of Japan in the context of "Liberal Democratic Party (Japan)"

The Government of Japan is the central government of Japan. It consists of legislative, executive and judiciary branches and functions under the framework established by the Constitution of Japan. Japan is a unitary state, containing forty-seven administrative divisions, with the emperor as its head of state. His role is ceremonial and he has no powers related to the Government. Instead, it is the Cabinet, comprising the prime minister and the ministers of state, that directs and controls the government and the civil service. The Cabinet has the executive power and is formed by the prime minister, who is the head of government. The Prime Minister is nominated by the National Diet and appointed to office by the Emperor. The current cabinet is the Takaichi Cabinet, which is led by prime minister Sanae Takaichi, who assumed office on 21 October 2025. The country has had a Liberal Democratic minority government since 2025.

The National Diet is the legislature, the organ of the Legislative branch. The Diet is bicameral, consisting of two houses with the House of Councilors being the upper house, and the House of Representatives being the lower house. The members of both houses of the Diet are directly elected by the people, who are the source of sovereignty. The Diet is defined as the supreme organ of sovereignty in the Constitution. The Supreme Court and other lower courts make up the Judicial branch and have all the judicial powers in the state. The Supreme Court has ultimate judicial authority to interpret the constitution and the power of judicial review. The judicial branch is independent from the executive and the legislative branches. Judges are nominated or appointed by the Cabinet and never removed by the executive or the legislature except during impeachment.

A designated city (指定都市, shitei toshi; [ɕi̥.tei toꜜ.ɕi, -teː-]) or government ordinance city (政令市, seireishi; [sei.ɾeꜜi.ɕi, seː.ɾeꜜː-]), short for city designated by government ordinance (政令指定都市, seirei shitei toshi; [sei.ɾei ɕi̥.tei toꜜ.ɕi, seː.ɾeː- -teː-]), is a Japanese city that has a population greater than 500,000 and has been designated as such by order of the Cabinet of Japan under Article 252, Section 19, of the Local Autonomy Law.

Designated cities are delegated many of the functions normally performed by prefectural governments in fields such as public education, social welfare, sanitation, business licensing, and urban planning. The city government is generally delegated the various minor administrative functions in each area, and the prefectural government retains authority over major decisions. For instance, pharmaceutical retailers and small clinics can be licensed by designated city governments, but pharmacies and hospitals are licensed by prefectural governments.

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 Japanese civil service employs over three million employees, with the Japan Self-Defense Forces, with 247,000 personnel, being the biggest branch. In the post-war period, this figure has been even higher, but the privatization of a large number of public corporations since the 1980s, including NTT, Japanese National Railways, and Japan Post, already reduced the number.

The vast majority of civil servants (2.74 million) are employed by local governments, while around 585,000 are national government civil servants. National civil servants are divided into "special" and "regular" service categories. Appointments in the special service category are governed by political or other factors and do not involve competitive examinations. This category includes cabinet ministers, heads of independent agencies, members of the Self-Defense Forces, Diet officials, and ambassadors.

The Imperial Investiture (親任式, Shinninshiki) is an official inauguration ceremony whereby the Emperor of Japan formally appoints the Prime Minister of Japan or the Chief Justice of Japan to office. In practice, the Prime Minister is nominated by the Diet, while the Chief Justice is nominated by the Cabinet. The Emperor is constitutionally required to appoint the nominated person, without the right to decline appointment.

During the time period of the Empire of Japan, as the Emperor was the source of executive authority, there were also investitures held for military officials. Such appointees were called the Shinninkan (親任官).

The Takaichi Cabinet is the 104th Cabinet of Japan, formed on 21 October 2025 when Sanae Takaichi was appointed Prime Minister by Emperor Naruhito as designated by the National Diet, following the resignation of Shigeru Ishiba after the 2025 Liberal Democratic Party presidential election.

The country's first woman-led government, it is also the first time that the Japan Innovation Party will participate in the national government, following the collapse of the LDP–Komeito coalition, which had governed from 1999 to 2009 and from 2012 to 2025, and the formation of the LDP–JIP coalition.

Sanae Takaichi (born 7 March 1961) is a Japanese politician who is serving as Prime Minister of Japan and President of the Liberal Democratic Party since 2025. She is the first woman to hold either of these positions. A member of the House of Representatives from 1993 to 2003 and since 2005, she also held several ministerial posts during the premierships of Shinzo Abe and Fumio Kishida.

Born and raised in Nara Prefecture, Takaichi graduated from Kobe University and worked as an author, legislative aide, and broadcaster before beginning her political career. Elected as an independent to the House of Representatives in the 1993 general election, she joined the Liberal Democratic Party (LDP) in 1996. A protégé of Prime Minister Abe, she held various positions during Abe's premiership, most notably as Minister for Internal Affairs and Communications. She was a candidate in the 2021 LDP leadership election, but was eliminated before the runoff, placing third. From 2022 to 2024, during Fumio Kishida's premiership, she served as the Minister of State for Economic Security.

The Constitution of the Empire of Japan (Kyūjitai: 大日本帝國憲法; Shinjitai: 大日本帝国憲法, romanized: Dai-Nippon Teikoku Kenpō), known informally as the Meiji Constitution (明治憲法, Meiji Kenpō), was the constitution of the Empire of Japan which was proclaimed on February 11, 1889, and remained in force between November 29, 1890, until May 2, 1947. Enacted after the Meiji Restoration in 1868, it provided for a form of mixed constitutional and absolute monarchy, based jointly on the German and British models. In theory, the Emperor of Japan governed the empire with the advice of his ministers; in practice, the Emperor was head of state but the Prime Minister was the actual head of government. Under the Meiji Constitution, the Prime Minister and his Cabinet were not necessarily chosen from the elected members of parliament.

During the Allied occupation of Japan, the Meiji Constitution was replaced with the "Postwar Constitution" on November 3, 1946; the latter document has been in force since May 3, 1947. In order to maintain legal continuity, the Postwar Constitution was enacted as an amendment to the Meiji Constitution.

The Tōjō Cabinet is the 40th Cabinet of Japan led by Hideki Tojo from 18 October 1941 to 22 July 1944.
