Head of state status and its discussion

Imperial Japanese ConstitutionUnlike the current Japanese constitution,Head of JapanThere is no provision regarding.From this, about the head of state of JapantheoryThere are various arguments above.

On the head of stateInternal cure,外交On behalf of the country throughAdministrative powerThere are various definitions, such as the state institution that is in control of the state, or the one that is in the position of head in the state without having a substantial power of national governance.Who qualifies as head of state is a matter of national law, but usuallyMonarchyThen.monarch,RepublicThen.PresidentIs this.The old constitution is clearEmperorWas the head of state.Under the current constitution, there is a theoretical dispute as to who should be regarded as the head of state, and there are theories that the emperor is the emperor, the prime minister is the prime minister, and there is no such thing. Be[11].

According to Kazuo NaganoNational democratic rightBelow, he is the head of a national institution that is qualified to represent the state, and also domestically.ControlThere is a strong opinion among scholars that the prime minister with the authority to exercise should be the head of state.[12].Nobuyoshi AbeAccording to the head of state, the most important requirement is to represent the state to foreign countries.authorityIt is supposed to be.However, in diplomatic relations, the emperor only allows formal and ceremonial acts in the constitution.Therefore, the head of state of Japan has the authority to conclude treaties, exempt from diplomatic missions, and handle diplomatic relations, and has the qualification of foreign representative as a national institution.CabinetOr the prime minister is the majority theory.[13][14]..Furthermore, there is a view that the emperor and the prime minister share the roles of head of state.[15].

On the other hand, there is a theory that it is sufficient for the head of state to have the authority to ceremonially represent the nation externally, and that a person in the position of a symbol of the nation has a head of state character, in which case the emperor is the head of state. Is considered.The emperor is treated as the head of state in international practice[5][6].. April 1973, 48 (Showa 4)71th DietHouse of Representatives Cabinet CommitteeInMinister of Foreign AffairsMasayoshi Ohira"I don't think there is a country that welcomes the Prime Minister as the head of state of Japan."[16].

In the past, there have been cases where a council of both houses was held, but there have been no cases where a draft was obtained. In addition, although there is no actual case, if the House of Councilors does not make a nomination within 10 days after the nomination of the House of Representatives, the nomination by the House of Representatives will be decided by the Diet (same as above).

Therefore, in effect,House of RepresentativesAccording to the intentions of the majority of the powers, the system is such that the leaders are nominated.


  1. Member of Parliament
    The Prime Minister shall be appointed from among the members of the Diet (Article 67, Paragraph 1 of the Constitution).

Therefore, the Prime Minister has the largest power in the House of Representatives.Political party OfParty leader, ま た はCoalitionOne of the heads of the political parties forming the party is appointed. Since the prime minister's requirement at the time of nomination of the leaders is stipulated as "member of the Diet",House of CouncilorsAny member may be used, but all Prime Ministers who took office after the enforcement of the Constitution of Japan were elected from the members of the House of Representatives. Although not specified by law, being a member of the Diet is both an election requirement and an employment requirement.[20].. HoweverDissolution of the House of RepresentativesEven if you lose a member of the House of Representatives due to the expiration of the term of officeHouse of Representatives general electionRemain in the position until the later convocation of the Diet.

There is an example.

In the precedent, the chair of the House of Representatives separately reports the nomination process directly to the Emperor at the Imperial Palace. The Emperor appoints the Prime Minister based on the appointment of the Diet (Article 6, Paragraph 1 of the Constitution).

There is no article in the Constitution of Japan that directly stipulates the term of office of the Prime Minister.

According to the constitution, when the Diet is first convened after the general election of the House of Representatives, the Cabinet must resign.Therefore, one term of the Prime Minister is It will not be longer than four years at the time when the first assembly is called after the election.[Annotation 7](Article 70 of the Constitution). Article 57 of the Public Offices Election Act stipulatesDeferred votingEven if this is done, it does not affect the number of days limit stipulated by the Constitution, so the effect of this cannot be expected. fundamentallyDeferred votingIs a provision for deferral at a particular polling place[Annotation 8]Because it is.

If the delay in voting in the general election of members of the House of Representatives delays the convocation of the Diet, of course, this provision does not prohibit re-election in the newly convened Diet, and institutionally as a member of the Diet. As long as he continues to be nominated by the head of the Diet, he can continue to be the Prime Minister.

However, usually the Prime MinisterRuling partyParty leaderHowever, if the party's internal rules impose re-election restrictions on the party leader, the term of office may be the de facto upper limit of the term of office.

The above is mandatory, and other than this, the Prime Minister can resign arbitrarily (resigned from the Cabinet). If the Prime Minister is lacking or resigns, the Cabinet must immediately notify both Houses.[23].

In addition, when "the Prime Minister has an accident" or "when the Prime Minister is missing", the Minister of State designated in advance will act as a temporary deputy for the Prime Minister (Article 9 of the Cabinet Law). Details will be described later.

In most cases under the Constitution of Japan, the Prime Minister resigns and at the same time the party leader of his own party resigns or resigns when his term expires.[Annotation 10].

Execution Cabinet

After the resignation of the Cabinet, the Cabinet before the resignation will continue to carry out its duties until the new Prime Minister is appointed (Article 71 of the ConstitutionTherefore, the Prime Minister after resigning from the Cabinet will continue to execute his duties.
Therefore, similarly, even if the Cabinet led by the temporary deputy prime minister resigns, the temporary deputy prime minister will continue to carry out his duties until the new prime minister is appointed.Therefore, to be precise, the resignation date of the Prime Minister is the day when he resigned from the Cabinet (Cabinet resignation).Cabinet decisionThe day the new Prime Minister was appointed.

Duty agency / assistant

Temporary deputy

There is a temporary deputy prime minister acting on behalf of the prime minister. This is not a regular position, and in the event of an accident with the Prime Minister, five pre-designated Ministers of State will take office in order. The one with the highest temporary substitute appointment rankingChief Cabinet SecretaryWhen you are a Minister of State other thanDeputy Prime MinisterCalled.

An example of a temporary representative placed indefinitely until the resignation of the Cabinet is:2st Ohira Cabinet OfMasayoshi ItoHowever, he took office as a temporary representative based on prior appointment after the death of the Prime Minister and immediately resigned from the Cabinet,Ishibashi Cabinet OfShinsuke KishiObuchi Cabinet OfMikio AokiHowever, there is an example in which he took office as a temporary representative immediately after being appointed by the prime minister who was hospitalized and resigned from the Cabinet. There are many cases in which the temporary agency acted for the job only during the Prime Minister's trip.


There is an assistant to the Prime Minister as an assistant to the Prime Minister. OrganizationallyCabinet SecretariatHowever, in terms of duties, he reports directly to the Prime Minister, not the Chief Cabinet Secretary.In addition, there are Special Advisors to the Cabinet, Special Advisor to the Cabinet, and Secretary to the Prime Minister, who support the execution of duties and the administration of the Prime Minister.


After the Meiji Restoration

Meiji RestorationAfter that, initiallyPledge of the Five ArticlesIn accordance with the policy of "Wide conference, the public decision, two-way decision,"Prime Minister SystemHas been done.However,Nara periodThis political regime that continued from the beginning was not only suitable for the new era and old-fashioned, but also for the institutional aspect,CondolenceWhat to doMinister-Left minister-Right ministerAnd is "commanded" by thisCouncilAnd each ministryLordIs not responsible forMinisterAlthough he was extremely busy, the responsibilities of the left and right ministers were unclear, which was a roundabout and inefficient task.

1880 (Meiji 13) From aroundCouncilIto HirobumiBegan to advocate this "Presidential" reform,MaintenanceRight minister of the factionIwakuraRepelled.At that time, Hirobumi Ito did not have the political power to counter the heavyweight Tomomi Iwakura.Therefore, Hirobumi Ito once withdrew this proposal.1882 (15th year of Meiji) From MarchDaiji Ito,Saionji public aspirationTraveled to Europe withGerman Empire,Austria-Hungary Empire,United KingdomIncluding the constitution inConstitutional systemThe skeleton of a “government equivalent to civilized countries” will be concretely constructed from this time. Hirofumi Ito, who returned to Japan after the death of Tomomi Iwakura, sought to advance the implementation of a political system concept in line with the constitutional system studied in Germany.

On the other hand, the same conservative minister, Prime Minister Iwakura,Minami SanjoResponded with a personnel reform proposal to assign Hirofumi Ito to the right minister. However, Hirofumi Ito politely declined this and insteadKiyotaka KurodaHowever, this time the "reform battle" ended in a draw, as the conservatives slumped into Kiyotaka Kuroda, who is now in a turmoil. After that, Hirofumi Ito and others were not afraid of this.CabinetProposing a system, "If you become a sovereign constitutional government, you must have the sovereignty over the legislation. As stated in Hirofumi Ito's vocabulary, "I can't help but act as if there is an act," as a set with the Constitution.ModernOfCabinet systemWhen confronted with the conservatives, there was no opposite name, and Hirofumi Ito's intention passed.

Prime Minister No. 69 and Cabinet Office

1885 On December 18, (12th year of Meiji), "Prime ministers"No. XNUMX" was issued, "Politics""Minister"on behalf"Cabinet"And the Prime Minister" were established, and the Cabinet system started here. In the "Cabinet" organizationMinister MiyauchiIs clearly not included,MiyanakaThe distinction between "(the court)" and "Fuchu (the government)" was stipulated, and the basis for a system in which each minister of affairs bears the administrative responsibility was born. Was enacted at the same timeCabinet authorityIn the above, the "Prime Minister" was given "Power of each minister, the leader of Toshite's mission, the direction of the government, and the direction of the major government. It was being done.

Cabinet system

1889 (Meiji 22)Imperial Japanese ConstitutionHowever, the Act does not specify direct provisions for the "Cabinet" and "Prime Minister", and in Article 55 of the same law, "Ministers of State Ha It was only specified. At the same time,Cabinet authorityWas established in the form of amendingCabinet systemIn the above, "the prime minister c. the heads of each minister's head, Toshite, to confirm the mission, maintain the unity of administrative departments" (Article 2), and its authority was weakened.

As for authority, the "Prime Minister" is said to be a "principal minister among his peers," who praises the Emperor, and the "Cabinet" was positioned as an organization for consultation and unification of the ministers. The Prime Minister has the governor-general of each department and has the instrumental performance right (the right to ask the Emperor to approve and the authority to declare the Emperor's approval) and the recommendation right to the Minister of State (to the Emperor) Although he had the authority to request an appointment), once a disagreement occurs within the cabinet, the Prime Minister cannot dismiss the ministers without the dismissal right of each minister, and he is only encouraged to persuade or resign. If this failsCabinet resignationI had no choice but to do it. As a caseTojo CabinetThe cause of the total resignation of theShinsuke KishiRefused to resign, andFirst Konoe CabinetIt is,Minister of Foreign Affairs OfYousuke MatsuokaI had no choice but to use the means of total resignation in order to quit. In addition, it was stipulated from the beginning of the Showa era until the end of the war in the Meiji period.Minister of the Military Active military systemDue to this, the Cabinet was restricted by the military. Especially when the Cabinet does not follow its will,Minister of ArmyAnd did not recommend a replacement,Second Saionji Cabinet-US CabinetCollapsed,Issei UgakiWas blocked from the Cabinet.

As a status,Next to the palace seat TheGrand OrderIn the position ofPrivy CouncilI am said to be higher than the chairman,RitualAbove, it was positioned as the highest rank in Fuchu.

Regarding appointment and dismissal, the Prime Minister is appointed by the Emperor as well as the Ministers of State (Big life drop), the selection method was not stipulated by law. From the early Meiji period to the early Showa periodVeteranWas appointed based on the recommendation byTaishoFrom the endShowaEarly on,Taisho democracyIs based on party politics byHouse of RepresentativesWas nominated and appointed the first party leader in (Constitutional road). After that, from the beginning of the Showa era until the end of the war, theShigeomi meetingHas been appointed by the recommendation.

Constitution of Japan and Cabinet Law

1946 (21)May 11ToThe Constitution of JapanWas promulgated,66 articleFor the first time, "the Cabinet shall, as provided for by law, organize this with the Prime Minister, who is its prime minister, and other Ministers of State."ConstitutionSpecified in. With this, the next1947 (22)May 1In the Cabinet Act enacted in April XNUMX, "The Prime Minister will direct and supervise each administrative department based on the policy decided during the Cabinet meeting" (6 article), etc., its authority was strengthened.

If there is a disagreement within the cabinet, the Prime Minister under the Constitution of Japan may dismiss and pass on his/her opinion. In addition, even if the Minister suddenly resigns for any reason, the Prime Minister may arbitrarily appoint his successor. This striking exampleRight to dissolve the House of RepresentativesIs. Under the constitution, the dissolution of the House of Representatives is to be done by the Emperor with the advice and approval of the Cabinet (Article 7 No. 3), This means that "the right to dissolve belongs to the Cabinet" and "the right to dissolve cannot be dissolved without a cabinet decision", but it is generally interpreted as "the right to dissolve is the exclusive matter of the Prime Minister". This is because even if there is a minister who refuses to sign the cabinet meeting in opposition to the dissolution, the prime minister can dismiss the minister and sign the cabinet meeting by himself.[Annotation 11].. Even if all ministers object, the prime minister can decide to disband by dismissing and concurrently serving as all ministers (One-person cabinet). Therefore, if the Prime Minister decides to disband, there is no law to prevent it. Thus, the effect of voluntary dismissal on ministers is extremely large.



Since the inception of the Cabinet System, the abbreviation for the Prime Minister has generally been "Prime ministerIs often used, but in addition to this,Prime Minister"Or"prime ministerThe abbreviation and common name are also used.[4]..Also known as "Prime ministerIs sometimes used[24].

English notation

The official English notation is "Prime MinisterIt is. This English translation had been used informally as the English translation of "Principal Minister" before the introduction of the Cabinet System. However, the English translation of "Prime Minister" did not mean this word from the beginning, and it used to be "Minister President of State"("country'sMinister-president) ”Meaning) was also used in the German translation.[Annotation 12].


Treatment of Minami Sanjo

In the transition to the Cabinet System, the concern for everyone was who became the first Prime Minister. The consensus of the eyes is that with the name of Taiji Minoru, who was the head of the government despite being a prime ministerToshimichi OkuboAfter his death, Hirofumi Ito was the de facto prime minister who built up the Cabinet system by encouraging the Meiji government. But SanjoFujiwara KitaIn the Kanain style,Seika familyIs one ofSanjo familyNoble of being bornidentity,DukeIs. On the other hand, Ito is a poor farmer,samuraiAlso became維新I'm from a low rank just beforePiagetHowever, the difference was clear. At the meeting in the palace that decided the first Prime Minister to replace the Prime MinisterJun Inoue”The future Prime MinisterRed Telegram (Foreign Telegram)You must be able to read it.” Yamamoto Ariho agreed, “Isn't there any other than Mr. Ito?”, and there is no word to return the conservatives' support for Sanjo. 、It was decided easily with this. The biggest factor in deciding the first Prime Minister was Ito's "English ability".

With the appointment of Prime Minister Ito, SanjoMinisterAs a palace, as an aide of the emperorEmperor MeijiWill be "Tsuyo Sasuke". However, the minister was originally created to treat Sanjo.Honorary positionSo, in fact, raise him upstairsLadderIt was like removing the. On the other hand, I once served SanjoMisaki Ozaki(Senate) Suggested that he should strongly protest against Sanjo, but he urged Ozaki to do such a contempt on the contrary, saying that it is for the future of the nation and not my own problem.[26].. However, whether Emperor Meiji was sorry for this treatment, 1889 (Meiji 22)May 10Second generation Prime Minister Kiyotaka KurodaTreaty revisionWhen he resigned as the Prime Minister taking responsibility for the political turmoil over the Empire, the Emperor accepted only Kuroda's resignation and rejected everything else, leaving Sanjo to serve concurrently as Prime Minister. This is not a "temporary concurrent appointment" but merely a "concurrent appointment", and the Emperor will be the next Yamagata YuhoGreat life of the CabinetIt was two months after that, so we consider that there was one separate cabinet during this period and call it the "Sanjo Provisional Cabinet".Even so, Sanetomi Sanetomi is not counted as a successive prime minister (note that the Emperor Meiji himself was pleased that he was the first prime minister to come out of the Kuge when he became prime minister of Saionji Kinmochi. " There is).


The incumbent Prime Minister has never lost an election.However, as an example of not being able to winMasayoshi OhiraCandidate for the House of Representatives election in 1980, but died before the ballot counting[Annotation 13].Middle-election systemMost of the current incumbent prime ministers were elected to the first place, but onlyYasuhiro NakasoneOnly in 1983 and 1986 are the second place elected in the two lower house elections (the first place isFukuda Yoshio).

As an example of a person who has experience with the Prime Minister being defeated in the national election, Satoshi Katayama (1949, 1963)Ishibashi Tozan(1963) andToshiki Kaifu(2009) is an example. Also,Naoto Kan(2012/2014)Small districtLost inProportional revivalI'm winning.Hosokawa GokiIn 2014 after retiring from politicsTokyo Governor ElectionI ran for, but lost.


The Prime Minister must be elected from members of the Diet.In legal theory, he can take office from the age of 25, when he is entitled to eligibility for a member of the House of Representatives.Legally, any member of the Diet may be nominated, regardless of which House of Representatives they belong to, but political experience is often emphasized, and the probability that a first-year member will be appointed. Is extremely rare (Hosokawa GohiWas elected prime minister in the House of Representatives once in 1993, but before taking office he was a member of the House of Councilors.KumamotoGovernorHad experience. In addition, Shigeru Yoshida was appointed prime minister in the House of Representatives once elected in 1948, and had prior experience as a member of the House of Representatives and the Minister of Foreign Affairs and Prime Minister).

The youngest Japanese prime minister to hold the record is the first Hirobumi Ito (1885 years old at the time) in 44, who is still unbroken.The oldest inauguration record in history1945 OfKantaro Suzuki(77 years old at that time), the oldest tenure record is Shigenobu Okuma (78 years old at that time). As the youngest after the war,2006 Is Shinzo Abe (52 years old at the time). The post-war oldest inauguration record isKijuro ShimeharaHowever, within the scope of the new constitution, it is 73 years and 72 months of Ishibashi Tanzan.

Education / educational background

There are no particular rules regarding educational background.

The early Prime Ministers were each youngEducation method of the Edo period (late Tokugawa period)I was educated and raised in France, but the first Prime Minister with an education in modern education was in France.Sorbonne UniversityToStudy abroadIt is Saionji Kinmochi.

(especially at Waseda UniversityWaseda University Oral SocietyThere is a speech circle that is sometimes regarded as "one of the gateways for politicians", and five people have been appointed as Prime Minister from 1956 to 2000).

Kakuei Tanaka has a background of studying at a vocational school (in a delicate position), and the "final academic background in the school system" isHigher elementary schoolGraduation[Annotation 14], I dared to make it my own appealing point.In addition, Sosuke Uno is an old systemKobe University of Commerce(CurrentKobe University), but two months laterStudent campAnd after the warSiberian detentionThe only student in Heisei, who dropped out without returning to schoolBachelor OfBachelor of ScienceIt became the prime minister who does not have.

After retirement

Even after retiring from the Prime Minister, if he / she wishes, about one personSecurity policeIt is customary for the (SP) to protect the former Prime Minister himself.[27]However, unlike the incumbent Prime Minister, who basically cannot refuse SP protection, it is possible to terminate SP protection at the will of the former Prime Minister himself.[28].
