Japan’s 2019 upper house election: Solidifying Abe, the LDP, and return to a one-party dominant political system

Abstract

Japan’s upper house, the House of Councillors, is a less powerful body than the House of Representatives, the lower house of the national Diet. Yet, electoral results of the upper house can have a significant impact on the government of the day, both for legislative purposes and for judging the credibility of the ruling party and its leader. This article analyses the July 2019 election and its likely impact on the Abe administration, and implications for Japan’s parliamentary democracy and party politics. The article argues that opposition forces are highly fragmented and weak, sustaining the LDP’s dominance in Japanese politics. Such a political landscape is welcomed by the ruling party and its leader, but continuing to entrench the hold on national governance by one dominant party is unhealthy for Japanese democracy.
