U.S. President Donald Trump and Japanese Prime Minister Shigeru Ishiba on Wednesday said they had struck a trade deal that will include a 15% tariff on U.S. imports from Japan. Here's what we know so far.

Japan will buy 100 Boeing aircraft and boost US defense equipment purchases under a new trade deal announced by the Trump administration.

Aside from the question of growth, the question is whether policymakers can reorient the country’s future trajectory before serious problems set in.
