A Brief History

1890 to 1947

Prior to World War II, the Imperial Diet of Japan was comprised of the House of Peers and the House of Representatives, as stipulated under the 1889 Constitution of the Empire of Japan. Whereas the House of Representatives was elected by the people, the House of Peers was made up of members of the imperial family, descendents of feudal lords, and other members appointed by the emperor.

1947 to present

Ever since the adoption of the current constitution following World War II, the Diet has consisted of the House of Councillors and the House of Representatives. Members of both houses are now elected directly by the citizenry.
