The ruling Liberal Democratic Party and junior coalition partner, Komeito, have maintained their majority in the Upper House, securing at least 63 seats in the election held July 21.

With the ruling coalition assured of the 123 seats needed in the 245-seat Upper House for a majority, Prime Minister Shinzo Abe can continue with a stable Diet as the ruling coalition will hold solid majorities in the two chambers.

In his campaign speeches, Abe said that he hoped to secure enough seats to ensure political stability and had set an extremely low goal of 53 seats total between his LDP and Komeito as the primary objective. That number would have given the ruling coalition a simple majority in the Upper House, but it has far exceeded that threshold.

Half the seats in the Upper House are up for election every three years. A total of 74 seats were contested in the prefectural districts with another 50 decided through proportional representation.
