岡田克也
During the nomination period of the July 2016 House of Councillors election, the party signed an agreement with the Democratic, Social Democratic and People's Life parties to field a jointly-endorsed candidate in each of the 32 districts in which only one seat is contested, uniting in an attempt to take control of the House from the LDP/Komeito coalition. JCP leaders have expressed willingness to enter into a coalition with the Democratic Party, a notion which was rejected by Democratic Party President Katsuya Okada as being "impossible" in the near future due to some of the "extreme leftist policies" promoted by the JCP. The party has three Councillors up for re-election and is fielding a total of 56 candidates in the election, down from 63 candidates in the 2013 election, but still the second-most behind the LDP. However, only 14 of those candidates are contesting single- and multi-member districts, while 42 will contest the 48-seat national proportional representation block.
