Osaka at-large district

The Osaka at-large district is a constituency of the House of Councillors that elects Councillors to represent Osaka Prefecture in the National Diet of Japan. From 1947 the district has elected three Councillors every three years by single non-transferable vote for six-year terms, such that there are six Councillors representing the district in the 242-member house. A revision to the Public Officers Electoral Law in 2012 increased the district's representation so that four Councillors were elected at the July 2013 election which will give the district a total eight Councillors by 2019.

The district has 7,140,578 registered voters (as of September 2015), making it the third-largest district behind the Tokyo and Kanagawa districts. The current Councillors for the district are:
