Sanae Takaichi made history by becoming the country's first female prime minister by winning a majority in both houses of parliament.

Takaichi, a member of the Liberal Democratic Party of Japan, took office with 237 votes in the lower house and 125 votes in the upper house.

The new prime minister has been a prominent figure in Japanese politics, earning her the nickname "Japan's Iron Lady."

The prime minister is a close confidant of the assassinated former Prime Minister, Shinzo Abe, and is known for her staunchly conservative stance.

Until now, Japan's leadership has been largely dominated by men, and now Sanae Takaichi is being hailed as a major breakthrough as she becomes the first female prime minister.

Many say the appointment of the prime minister is a historic step in the gradual shift towards greater female representation in Japanese politics.

Prime Minister Sanae Takaichi is the fourth female prime minister to come to power in five years in Japan's volatile political landscape.

Takaichi's victory came at a time when his party, the Liberal Democratic Party, was embroiled in a political scandal and its public approval ratings were low.
