List of members of the Diet of Japan
This is a list of members of the Diet of Japan. The Diet has two chambers: the House of Councillors (upper house) and the House of Representatives (lower house). Councillors serve six year terms, with half being elected every three years. Representatives serve terms of up to four years, but the House of Representatives can be dissolved, causing a shorter term (snap election).

The following table lists members of the House of Representatives by constituency and parliamentary group (会派, kaiha) as of 18 February 2026. The elected party column shows the party under which each member was elected; the parliamentary group column shows their current parliamentary group membership, which may differ.
Notes:
- Not all members of a parliamentary group are necessarily members of the associated party/parties if any, and vice versa. For example, the Speaker and Vice-Speaker of the House of Representatives are independents in terms of parliamentary group membership, but not independents in terms of party membership.
