TOKYO—Japanese Prime Minister Shinzo Abe was re-elected as head of his ruling Liberal Democratic Party in a landslide on Sept. 20, paving the way for up to three more years as the nation’s leader and a push toward a constitutional revision.
The decisive victory may embolden Abe to pursue his long-sought amendment to Japan’s U.S.-drafted pacifist constitution, although the hurdles remain high and doing so would carry political risks.
