It is heartening that female candidates performed well in this election, as Japan lags behind the rest of the developed world in terms of gender equality. Japan has never had a female prime minister, and women in politics are often evaluated based on their looks instead of their substance. While the election was a notably sleepy one, it still represented a solid step forward.
This election was emblematic of everything that's gone awry with Japanese politics. A proliferation of fringe and joke candidates muffled real opposition to an entrenched status quo that the population is growing disaffected with. An incumbent has never lost an election in Tokyo, and Koike benefited from apparent connections to the news media to boot. There's little to write home about in this election.
