Japan election: Surge of women candidates could reshape male-dominated parliament

A woman casts her vote at a polling station in Japan. Sunday's upper house election could see a dramatic increase in the number of female lawmakers.

(CNN)One of the world's most unequal parliaments could be about to get a lot more female, or ... maybe not.

Voting is underway in Japan's general election, where a record number of women are running for office to fill 124 of the 245 seats in the upper House of Councilors.
Half of the upper chamber of the National Diet is elected every three years and this election includes three new seats.
Of the 370 candidates running this year, 104 -- or almost 30% -- are women, according to public broadcaster NHK.
