The Chūseikai (Japanese: 中正会, lit. Impartiality Society) was a political party in Japan.
The party was established in December 1913 as a merger of Ekirakukai and Seiyū Club and initially had 37 MPs.[1] It supported Ōkuma Shigenobu's government from 1914 until 1916, with party member Yukio Ozaki appointed Minister of Justice.[1] In the 1915 general elections it won 33 seats, and in October 1916 it merged into the new Kenseikai party.
