The prime minister of Japan (日本国内閣総理大臣 Nihon-koku naikaku sōridaijin?, or shushō (首相?)) (informally referred to as the PMOJ) is the head of government of Japan, the chief executive of the National Cabinet and the commander-in-chief of the Japanese Armed Forces; he is appointed by the emperor of Japan after being designated by the National Diet and must enjoy the confidence of the House of Representatives to remain in office. He is the head of the Cabinet and appoints and dismisses the other ministers of state. The literal translation of the Japanese name for the office is Minister for the Comprehensive Administration of (or the Presidency over) the Cabinet.

The current prime minister of Japan is Yoshihide Suga. On 14 September 2020, he was elected to the presidency of the governing Liberal Democratic Party (LDP). After being confirmed in the Diet, he received an invitation from Emperor Naruhito to form a government as the new prime minister, and took office on 16 September 2020, replacing Shinzō Abe who resigned for health reasons.[2] Suga announced on 3 September 2021 that he would not seek reelection as President of the LDP, which will effectively end his term as Prime Minister after just one year.[3] [4]


Before the adoption of the Meiji Constitution, Japan had in practice no written constitution. Originally, a Chinese-inspired legal system known as ritsuryō was enacted in the late Asuka period and early Nara period. It described a government based on an elaborate and rational meritocratic bureaucracy, serving, in theory, under the ultimate authority of the Emperor; although in practice, real power was often held elsewhere, such as in the hands of the Fujiwara clan, who intermarried with the Imperial Family in the Heian period, or by the ruling shōgun. Theoretically, the last ritsuryō code, the Yōrō Code enacted in 752, was still in force at the time of the Meiji Restoration.

Under this system, the Daijō-daijin (太政大臣?, Chancellor of the Realm)[5] was the head of the Daijō-kan (Department of State), the highest organ of Japan's pre-modern Imperial government during the Heian period and until briefly under the Meiji Constitution with the appointment of Sanjō Sanetomi in 1871. The office was replaced in 1885 with the appointment of Itō Hirobumi to the new position of Prime Minister,[6] four years before the enactment of the Meiji Constitution, which mentions neither the Cabinet nor the position of Prime Minister explicitly.[7][8] It took its current form with the adoption of the Constitution of Japan in 1947.

To date, 64 people have served this position. The longest serving prime minister to date is Shinzō Abe, who served as prime minister in two terms: from 26 September 2006 until 26 September 2007, and from 26 December 2012 until 16 September 2020.[9]


The prime minister is designated by both houses of the Diet, before the conduct of any other business. For that purpose, each conducts a ballot under the run-off system. If the two houses choose different individuals, then a joint committee of both houses is appointed to agree on a common candidate. Ultimately, however, if the two houses do not agree within ten days, the decision of the House of Representatives is deemed to be that of the Diet. Therefore, the House of Representatives can theoretically ensure the appointment of any prime minister it wants.[10] The candidate is then presented with his or her commission, and formally appointed to office by the Emperor.[11]

Conventionally, the prime minister is almost always the leader of the majority party in the House of Representatives, or the leader of the senior partner in the governing coalition. But there have been three cabinet prime ministers from junior coalition partners (Ashida 1948, Hosokawa 1993, Murayama 1994), a few minority governments (most recently the Hata Cabinet in 1994 and at least numerically the Second Hashimoto Cabinet of 1996 during its first year, but with an extra-cabinet cooperation (閣外協力, kakugai kyōryoku) agreement with two parties, sufficient to ensure safe majorities for most government initiatives), and several cabinets with a majority in the House of Representatives, but without legislative majority of their own (most recently the DPJ-led cabinets after the 2010 election; cf. Nejire Kokkai/"twisted Diets").


  • Must be a member of either house of the Diet. (This implies a minimum age of 25 and a Japanese nationality requirement.)
  • Must be a civilian. This excludes serving members of the Japan Self-Defense Forces. Former military persons may be appointed prime minister, Yasuhiro Nakasone being one prominent example.


Constitutional roles

  • Exercises "control and supervision" over the entire executive branch.[12]
  • Presents bills to the Diet on behalf of the Cabinet.[13]
  • Signs laws and Cabinet orders (along with other members of the Cabinet).[14]
  • Appoints all Cabinet ministers, and can dismiss them at any time.[15]
  • May permit legal action to be taken against Cabinet ministers.[16]
  • Must make reports on domestic and foreign relations to the Diet.[13]
  • Must report to the Diet upon demand to provide answers or explanations.[17]
  • May advise the Emperor to dissolve the Diet's House of Representatives.[18]

Statutory roles

Unlike most of his counterparts in constitutional monarchies, the prime minister is both de jure and de facto chief executive. In most other constitutional monarchies, the monarch is nominal chief executive, while being bound by convention to act on the advice of the cabinet. In contrast, the Constitution of Japan explicitly vests executive power in the Cabinet, of which the prime minister is the leader. His countersignature is required for all laws and Cabinet orders. While most ministers in parliamentary democracies have some freedom of action within the bounds of cabinet collective responsibility, the Japanese Cabinet is effectively an extension of the prime minister's authority.


Official office and residence

Located near the Diet building, the Office of the Prime Minister of Japan is called the Kantei (官邸?). The original Kantei served from 1929 until 2002, when a new building was inaugurated to serve as the current Kantei.[22] The old Kantei was then converted into the Official Residence, or Kōtei (公邸?).[23] The Kōtei lies to the southwest of the Kantei, and is linked by a walkway.[23]


The Prime Minister of Japan travels in a Toyota Century, which replaced the Lexus LS 600h L in 2019.

For overseas air travel, the Japanese government maintains two Boeing 777, which replaced the Boeing 747-400 also in 2019. The aircraft is also used by the emperor, the members of the Imperial family, and other high-ranking officials.

They have the radio callsigns Japanese Air Force One and Japanese Air Force Two when operating on official business, and Cygnus One and Cygnus Two when operating outside of official business (e.g., on training flights). The aircraft always fly together on government missions, with one serving as the primary transport and the other serving as a backup with maintenance personnel on board. The aircraft are officially referred to as Japanese government exclusive aircraft (日本国政府専用機 Nippon-koku seifu sen'yōki?).[24]

Honours and emoluments

Until the mid-1930s, the prime minister of Japan was normally granted a hereditary peerage (kazoku) prior to leaving office if he had not already been ennobled. Titles were usually bestowed in the ranks of count, viscount or baron, depending on the relative accomplishments and status of the prime minister. The two highest ranks, marquess and prince, were only bestowed upon highly distinguished statesmen, and were not granted to a prime minister after 1928. The last prime minister who was a peer was Baron Kijūrō Shidehara, who served as Prime Minister from October 1945 to May 1946. The peerage was abolished when the Constitution of Japan came into effect in May 1947.

Certain eminent prime ministers have been awarded the Order of the Chrysanthemum, typically in the degree of Grand Cordon. The highest honour in the Japanese honours system, the Collar of the Order of the Chrysanthemum, has only been conferred upon select prime ministers and eminent statesmen; the last such award to a living prime minister was to Saionji Kinmochi in 1928. More often, the Order of the Chrysanthemum has been a posthumous distinction; the Collar of the order was last awarded posthumously to former prime minister Yasuhiro Nakasone in November 2019. The Grand Cordon has typically been posthumously awarded; the most recent such award was to Ryutaro Hashimoto in July 2006.

After relinquishing office, the prime minister is normally accorded the second or senior third rank in the court order of precedence, and is usually raised to the senior second rank posthumously. Certain distinguished prime ministers have been posthumously raised to the first rank; the last such award was to Sato Eisaku in 1975. Since the 1920s, following their tenure in office, Prime ministers have typically been conferred with the Grand Cordon of the Order of the Paulownia Flowers (until 2003 a special higher class of the Order of the Rising Sun), depending on tenure and eminence. However, honours may be withheld due to misconduct or refusal on the part of the prime minister (for example, Kiichi Miyazawa).
