Sanae Takaichi has been elected Japan's prime minister by its parliament, making her the first woman to hold the office, BBC reported.
The 64-year-old won a clear majority on Tuesday - 237 votes in the powerful Lower House and another 125 in the Upper House - as leader of the ruling Liberal Democratic Party (LDP).
A staunch conservative and admirer of the late former UK PM Margaret Thatcher, Takaichi takes over at a challenging economic moment as Japan grapples with a rising cost of living and a frustrated public.
It's also been an uncertain time for the world's fourth-largest economy. She is the fourth PM in just five years, after her predecessors' terms were cut short by plunging ratings and scandals, according to BBC.
