Sanae Takaichi won the lower house of parliament vote to become Japan’s prime minister on Tuesday, effectively making her the first woman to clinch the nation’s top leadership job.

Her ascension to the premiership is a historic feat in a country that has ranked low in female political representation. With that achievement out of the way, Takaichi will now face a range of challenges that include persistent inflation, a tense security environment and simmering domestic political instability.

Among her first orders of business is to cobble together a cabinet, which she is expected to unveil later Tuesday. In coming days she’ll also have a string of diplomatic events to attend to, including a possible visit to Japan by US President Donald Trump next week.
