== List of sessions ==

There are three types of sessions of the National Diet:<ref>House of Councillors: [http://www.sangiin.go.jp/japanese/aramashi/syousyu_kaiki.html 国会の召集と会期] {{Webarchive|url=https://web.archive.org/web/20171113003433/http://www.sangiin.go.jp/japanese/aramashi/syousyu_kaiki.html |date=November 13, 2017 }}</ref>
* R – ''jōkai'' (常会), regular, annual sessions of the National Diet, often shortened to "regular National Diet" (通常国会, ''tsūjō Kokkai''). These are nowadays usually called in January, they last for 150 days and can be extended once.
* E – ''rinjikai'' (臨時会), extraordinary sessions of the National Diet, often shortened to "extraordinary National Diet" (臨時国会, ''rinji Kokkai''). These are often called in autumn, or in the summer after a regular election of the [[House of Councillors]] (参議院議員通常選挙, ''sangiingiin tsūjōsenkyo'') or after a full-term general election of the [[House of Representatives (Japan)|House of Representatives]] (衆議院議員総選挙, ''shūgiingiin sōsenkyo''). Its length is negotiated between the two houses, it can be extended twice.
* S – ''tokubetsukai'' (特別会), special sessions of the National Diet, often shortened to "special National Diet" (特別国会, ''tokubetsu Kokkai''). They are called only after a dissolution and early general election of the House of Representatives. Because the [[Cabinet of Japan|cabinet]] must resign after a House of Representatives election, the National Diet always chooses a prime minister-designate in a special session (but inversely, not all PM elections take place in a special Diet). A special session can be extended twice.
* HCES – There is a fourth type of legislative session: If the House of Representatives is dissolved, a National Diet cannot be convened. In urgent cases, the cabinet may invoke an emergency session (緊急集会, ''kinkyū shūkai'') of the House of Councillors to take provisional decisions for the whole Diet. As soon as the whole National Diet convenes again, these decisions must be confirmed by the House of Representatives or become ineffective. Such emergency sessions have been called twice in history, in 1952 and 1953.<ref>House of Councillors: [http://www.sangiin.go.jp/japanese/aramashi/kinkyu_syukai.html 参議院の緊急集会] {{Webarchive|url=https://web.archive.org/web/20171209221007/http://www.sangiin.go.jp/japanese/aramashi/kinkyu_syukai.html |date=December 9, 2017 }}</ref>

Any session of the National Diet may be cut short by a dissolution of the House of Representatives (衆議院解散, ''shūgiin kaisan''). In the table, this is listed simply as "(dissolution)"; the House of Councillors or the National Diet as such cannot be dissolved.
