Japanese National Assembly


May 29, 2022

The National Diet (National Diet) is the legislative branch of the central government of Japan. It is the supreme institution of national sovereignty under the Constitution of Japan and the only legislative body in Japan. The National Assembly Building, used for medical purposes, is located in Chiyoda-ku, Tokyo.


In 1874, Daisuke Itagaki and others submitted the “White Paper on the Establishment of the People’s Election Assembly”. In 1881, Emperor Meiji issued an ordinance promising to open the National Assembly 10 years later. The Constitution of the Empire of Japan was promulgated in 1889. Established by the bicameral imperial parliament, which consists of the nobility and the lower house. 1890 First Imperial Assembly opened. 1936 The Imperial Diet Building (now the National Assembly Building) was completed. In 1947, the Constitution of Japan came into force. As the highest organ of national power, a bicameral National Assembly consisting of the House of Representatives and the House of Representatives was established, and the 1st National Assembly was opened.


The National Assembly consists of the House of Representatives and the House of Representatives. The House of Representatives corresponds to the House of Representatives and the House of Representatives to the Senate, and both houses are made up of members of the National Assembly who are elected by the people who are sovereign. There is a secretariat and a legislative branch, respectively, as institutions supporting both houses. Also, there is the National Assembly Library as an auxiliary institution that is not under the direct control of the Parliament. In addition, the Judge Prosecution Committee and the Judges Impeachment Tribunal have been established to carry out the impeachment of judges of the National Assembly as stipulated in the Constitution of Japan.

The National Assembly is active only during the session. However, the committee may conduct a review even at the time of adjournment through the procedures prior to adjournment. General Assembly (Normal National Assembly: Regular meeting) It is convened once a year, in January, and the session is 150 days. It can be extended once. Temporary Meeting (Temporary National Assembly) The Cabinet decides to convene as needed. A decision to convene is unavoidable when there is a request of at least one-fourth of the total number of members of the House of Representatives. The session is determined by a unanimous resolution of both houses and can be extended up to two times. Special Session (Special National Assembly) Convenes after the general election due to the dissolution of the House of Representatives. The decision of the session is the same as that of an extraordinary session. When an urgent resolution issue arises during the period between the dissolution of the House of Representatives and the period before the special session, the House of Councilors may hold an emergency meeting. Although the resolution of the emergency assembly has the effect of a resolution of the National Assembly, it is only temporary, and if the consent of the House of Representatives is not obtained after the death, it loses its effect thereafter.


While the plenary session was the center of the deliberations on the agenda of the imperial assembly era, the post-war National Assembly deliberated the agenda centered on the committee. Each National Assembly committee has a permanent standing committee and a special committee that can be set up as needed for each agenda item. In addition, a committee has been established for long-term, in-depth investigation without waiting for the delegation of specific agenda items.
