1930's Japanese Politics / Postcards : Poster Art for Election of the Diet Members / " senkyo shukusei undo " (election discipline movement)

Electoral fraud or vote rigging was one of huge political issues in Japan in the 1930's.

Government bureaucrats thought big influential parties & party politics itself were causing this problem, so, carried out a political movement called "senkyo shukusei undo" (election discipline movement) in order to weaken political parties. 

And, linking this movement with patriotism worked well to appeal to people.
