Kenseikai was a Japanese political party active during the Taishō era, primarily known for its advocacy of democracy and political reform. Founded in 1916 by former members of the Seiyūkai, Kenseikai aimed to push for more liberal policies and parliamentary democracy in Japan. The party played a crucial role in the movement towards Taishō democracy by promoting the interests of the common citizen and seeking to reduce the power of the military and oligarchs in government.
