Diet of Japan
Encyclopedia
The is Japan's bicameral
legislature. It is composed of a lower house
, called the House of Representatives
, and an upper house
, called the House of Councillors
. Both houses of the Diet
are directly elected under a parallel voting system
. In addition to passing laws, the Diet is formally responsible for selecting the Prime Minister
. The Diet was first convened as the Imperial Diet in 1889 as a result of adopting the Meiji constitution
. The Diet took its current form in 1947 upon the adoption of the postwar constitution
and is considered by the Constitution to be the highest organ of state power. The National Diet Building
is located in Nagatachō, Chiyoda, Tokyo

in Japan) may vote in these elections. Japan's parallel voting system is not to be confused with the Additional Member System
used in many other nations.
The Constitution of Japan
does not specify the number of members of each house of the Diet, the voting system, or the necessary qualifications of those who may vote or be returned in parliamentary elections
, thus allowing all of these things to be determined by law. However it does guarantee universal adult suffrage and a secret ballot. It also insists that the electoral law must not discriminate in terms of "race, creed, sex, social status, family origin, education, property or income".
Generally, the election of Diet members is controlled by statutes passed by the Diet. Because the Liberal Democratic Party
has controlled Japan for most of its postwar history, and gains much of its support from rural areas, rural areas generally have more representation in the Diet than do urban areas. The Supreme Court of Japan
began exercising judicial review
of apportionment laws following the Kurokawa decision of 1976, invalidating an election in which one district in Hyōgo Prefecture
received five times the representation of another district in Osaka Prefecture
. The Supreme Court has since indicated that the highest electoral imbalance permissible under Japanese law is 3:1, and that any greater imbalance between any two districts is a violation of Article 14 of the Constitution. In recent elections the malapportionement ratio amounted to 4.8 in the House of Councillors (census 2005: Ōsaka/Tottori; election 2007: Kanagawa/Tottori) and 2.3 in the House of Representatives (election 2009: Chiba 4/Kōchi 3).
Candidates for the lower house must be 25 years old or older and 30 years or older for the upper house. All candidates must be Japanese nationals. Under Article 49 of Japan's constitution, Diet members are paid about ¥1.3 million a month in salary. Each lawmaker is entitled to employ three secretaries with taxpayer funds, free train tickets, and four round-trip airplane tickets a month to enable them to travel back and forth to their home districts.
describes the National Diet as "the highest organ of state power" and "the sole law-making organ of the State". This statement is in forceful contrast to the Meiji Constitution
, which described the emperor
as the one who exercised legislative power with the consent of the Diet. The Diet's responsibilities include not only the making of laws but also the approval of the annual national budget that the government submits and the ratification of treaties. It can also initiate draft constitutional amendments, which, if approved, must be presented to the people in a referendum. The Diet may conduct "investigations in relation to government" (Article 62). The prime minister
must be designated by Diet resolution, establishing the principle of legislative supremacy over executive government agencies (Article 67). The government can also be dissolved by the Diet if it passes a motion of no confidence introduced by fifty members of the House of Representatives. Government officials, including the prime minister and cabinet members
, are required to appear before Diet investigative committees and answer inquiries. The Diet also has the power to impeach judges convicted of criminal or irregular conduct.
In most circumstances, in order to become law a bill must be first passed by both houses of the Diet and then promulgated by the Emperor
. This role of the Emperor is similar to the Royal Assent
in some other nations; however, the Emperor cannot refuse to promulgate a law and therefore his legislative role is merely a formality.
The House of Representatives is the more powerful chamber of the Diet. While the House of Representatives cannot usually overrule the House of Councillors on a bill, the House of Councillors can only delay the adoption of a budget or a treaty that has been approved by the House of Representatives, and the House of Councillors has almost no power at all to prevent the lower house from selecting any Prime Minister it wishes. Furthermore, once appointed it is the confidence of the House of Representatives alone that the Prime Minister must enjoy in order to continue in office. The House of Representatives can overrule the upper house in the following circumstances:
. In an emergency the Cabinet can convoke the Diet for an extraordinary session, and an extraordinary session may be requested by one quarter of the members of either house. At the beginning of each parliamentary session the Emperor reads a special speech
outlining the government's plans for the coming year from his throne in the chamber of the House of Councillors.
The presence of one third of the membership of either house constitutes a quorum
and deliberations are in public unless at least two-thirds of those present agree otherwise. Each house elects its own presiding officer who exercises the casting vote in the event of a tie. Members of each house have certain protections against arrest while the Diet is in session and words spoken and votes cast in the Diet enjoy parliamentary privilege
. Each house of the Diet determines its own standing orders and has responsibility for disciplining its own members. A member may be expelled, but only by a two-thirds majority vote. Every member of the Cabinet has the right to appear in either house of the Diet for the purpose of speaking on bills, and each house has the right to compel the appearance of Cabinet members.
in force from 1889 to 1947. The Meiji Constitution was adopted on February 11, 1889 and the Imperial Diet first met on November 29, 1890 when the document entered into operation. The Diet consisted of a House of Representatives and a . The House of Representatives was directly elected, if on a limited franchise; universal adult male suffrage was introduced in 1925. The House of Peers, much like the British House of Lords
, consisted of high ranking nobles.
The word diet
derives from Latin
and was a common name for an assembly in medieval Germany
. The Meiji constitution was largely based on the form of constitutional monarchy found in nineteenth century Prussia
and the new Diet was modeled partly on the German Reichstag
and partly on the British Westminster system
. Unlike Japan's modern constitution, the Meiji constitution granted a real political role to the Emperor, although in practice the Emperor's powers were largely directed by a group of oligarchs called the genrō
.
To become law or bill, a constitutional amendment had to have the assent of both the Diet and the Emperor. This meant that while the Emperor could no longer legislate by decree he still had a veto over the Diet. The Emperor also had complete freedom in choosing the Prime Minister and the Cabinet, and so, under the Meiji constitution, Prime Ministers often were not chosen from and did not enjoy the confidence of the Diet. The Imperial Diet was also limited in its control over the budget. While the Diet could veto the annual budget, if no budget was approved the budget of the previous year continued in force.
The proportional representation system for the House of Councillors, introduced in 1982, was the first major electoral reform under the postwar constitution. Instead of choosing national constituency candidates as individuals, as had previously been the case, voters cast ballots for parties. Individual councillors, listed officially by the parties before the election, are selected on the basis of the parties' proportions of the total national constituency vote. The system was introduced to reduce the excessive money spent by candidates for the national constituencies. Critics charged, however, that this new system benefited the two largest parties, the LDP and the Japan Socialist Party, which in fact had sponsored the reform.

- If both houses cannot agree on a budget or a treaty, even through the appointment of a joint committee of the Diet, or if the House of Councillors fails to take final action on a proposed budget or treaty within 30 days of its approval by the House of Representatives, then the decision of the lower house is deemed to be that of the Diet.

This meant that while the Emperor could no longer legislate by decree he still had a veto over the Diet. The Emperor also had complete freedom in choosing the Prime Minister and the Cabinet, and so, under the Meiji constitution, Prime Ministers often were not chosen from and did not enjoy the confidence of the Diet. The Imperial Diet was also limited in its control over the budget. While the Diet could veto the annual budget, if no budget was approved the budget of the previous year continued in force.
The proportional representation system for the House of Councillors, introduced in 1982, was the first major electoral reform under the postwar constitution. Instead of choosing national constituency candidates as individuals, as had previously been the case, voters cast ballots for parties. Individual councillors, listed officially by the parties before the election, are selected on the basis of the parties' proportions of the total national constituency vote. The system was introduced to reduce the excessive money spent by candidates for the national constituencies. Critics charged, however, that this new system benefited the two largest parties, the LDP and the Japan Socialist Party, which in fact had sponsored the reform.
