Japan’s fifth premier in as many years also leads a minority government and has a bulging in-tray, not least a scheduled visit by US President Donald Trump next week.
The former heavy metal drummer and Margaret Thatcher admirer became head of the Liberal Democratic Party (LDP) on October 4, but its coalition collapsed days later.
This forced Takaichi to form an alliance with the reformist, right-leaning Japan Innovation Party (JIP), which was signed on Monday.
She was approved by parliament as prime minister on Tuesday and was due formally to take office later in the day when she meets the emperor.
EU chief Ursula von der Leyen congratulated Takaichi for “making history” as Japan’s first woman premier.
Takaichi had promised a cabinet with “Nordic” levels of women, up from two under predecessor Shigeru Ishiba. The record for Japan is five.
But she named only two other women in her 19-strong cabinet, with Satsuki Katayama in charge of finances and the Japanese-American Kimi Onoda taking on the economic security portfolio.
Japan ranked 118 out of 148 in the World Economic Forum’s 2025 Global Gender Gap Report. Around 15 percent of lower house MPs are women.
Takaichi has said she hopes to raise awareness about women’s health struggles and has spoken candidly about her own experience with menopause.
But she is seen as socially conservative, opposing revising a 19th-century law requiring married couples to share the same surname, and wants the imperial family to stick to male-only succession. AFP
