A group of Japanese professors has revealed an estimate of gender gap indexes for Japan's 47 prefectures in a bid to call attention to inequality between men and women, as the country marks International Women's Day on Tuesday.
The indexes, calculated based on 28 items from government statistics and other data, rank the prefectures by gender equality in the areas of politics, administration, education and economy. The closer the figure is to one, the smaller the gender gap.
Tokyo, where about 30% of metropolitan assembly members are women, topped the list in politics but has room for improvement, with its index standing at 0.292.
