Japan’s Sanae Takaichi and her ruling Liberal Democratic Party secured an overwhelming mandate in Sunday’s election, sweeping a supermajority — which means the LDP holds two-thirds or more seats in the Lower House — and ushering her back as the country’s prime minister.

The outcome gives Takaichi broad latitude to pursue her agenda, which includes boosting spending and suspending some food-related taxes. Japanese stocks climbed to a record high Monday, while the yen

strengthened to 156.88 per dollar, reflecting renewed investor confidence following the election results.
