A group of Japanese women went on "sex strike" against men who voted for Yoichi Masuzoe for Tokyo governor.

The Twitter campaign group wanted to prevent Mr Masuzoe, who once said that menstruation made women unfit for government, from being elected.

Despite the group gaining 3,000 followers since its launch a week ago, the pro-nuclear former cabinet minister won the election on Sunday.

Japan Times journalist Jake Adelstein told BBC Radio 5 live's Up All Night: "There's a huge gender gap, and he kind of personifies the gender gap."
