The Liberal Democratic Party won the most seats, but failed to win a majority.

The left parties aimed to win at least a third of seats to prevent any constitutional change.

Another issue was the government's plan to replace the elected prefectural boards of education with appointed ones, a plan fiercely opposed by the left: In June 1956, on the LDP's request the police intervened in the "deliberations" in the Diet when Socialist Councillors resorted to violence.

Takenaka Tsuneo, who was elected as a member of the Japan Dentists' Federation, later joined the LDP.
