Sanae Takaichi has officially become Japan's first female prime minister following her victory in the lower house vote on Tuesday. This marks a significant milestone in a country where women have historically been underrepresented in politics. Takaichi garnered 237 votes, surpassing the 233 required for a majority in the 465-seat lower house. It is anticipated that she will also receive approval from the upper house, which holds less influence, and will be inaugurated as Japan's 104th prime minister later today. Takaichi now confronts a range of challenges, including ongoing inflation, regional security tensions, and political instability domestically.
