The 64-year-old angered the Tokyo branch of Prime Minister Shinzo Abe's Liberal Democratic Party by not getting its approval before announcing her candidacy for city governor. She opted to run as an independent and LDP instead drafted Masuda, 64.

“I am in awe to see that when individual votes becomes one, it can turn into a huge wave,” Koike told reporters at her campaign office on Monday after clinching her victory.

Her predecessor resigned on June 15 after admitting he used thousands in taxpayer money to fund family trips and artwork.

Koike joins the swelling ranks of women who have recently been elected or chosen to run countries and major cities.

On June 19, Virginia Raggi was elected Rome's first female mayor in its almost 3,000-year history, giving Italy's anti-establishment Five Star Movement its biggest victory to date.

On July 13, Theresa May became Britain’s prime minister. She replaced David Cameron, who became the first political casualty of the Brexit referendum when he announced his intention to quit hours after the result.

Koike mobilized support by promising environmentally friendly policies for the capital. She urged voters to wear green at her campaign rallies in a nod to her days as environment minister when she called for office workers to set aside their jacket and ties in favor energy saving lighter clothes.
