Japan’s Prime Minister Shigeru Ishiba faces a critical test in Sunday’s upper house election. A loss could deepen political instability as his government struggles with rising prices, U.S. tariffs and voter dissatisfaction.

U.S. Treasury Secretary Scott Bessent told Japanese Prime Minister Shigeru Ishiba that their countries can reach a "good agreement" on tariffs, Ishiba said on Friday after meeting Bessent at his office in Tokyo.
