Tokyo has elected a new governor despite a "sex strike" held by a group of women in protest against men who voted for him.
The action from "the association of women who will not have sex with men who vote for Masuzoe" comes after 65-year-old Yoichi Masuzoe said in an interview with a men's magazine in 1989 that women are "not normal" during their periods, and are therefore unfit to govern.
Three thousand women are following the campaign since it started last week, the Guardian reported.
Their profile reads: "We have stood up to prevent Mr Masuzoe, who makes such insulting remarks against women [from being elected] ... We won't have sex with men who will vote for Mr Masuzoe."
Backed by Prime Minister Shinzo Abe, Masuzoe won Tokyo's gubernatorial election on Sunday, and was given a mandate to restart Japan's 50 nuclear reactors.
