TOKYO — Japan’s parliament elected ultraconservative Sanae Takaichi as the country’s first female prime minister Tuesday, a day after her struggling party struck a coalition deal with a new partner expected to pull her governing bloc further to the right.

With far-right Sanae Takaichi in power, Japan’s anti-immigration forces are likely to prevail and immigration reforms may end soon. In the ageing society, immigration is seen important for growth but nativist politics appears to have trumped.

Japan ranks low in gender equality among developed nations. The first woman to lead the country is an ultraconservative who cites Margaret Thatcher as a role model. She also loves heavy metal.
