Prime Minister Ishiba Shigeru and his Liberal Democratic Party were projected to lose their majority coalition government in Japan's Upper House of Parliament on Monday.

The ruling LDP has only been able to remain in office as a minority government as a result of the deep divisions among the opposition parties—between the far-right and the nominally liberal parties.

Japan’s shaky ruling coalition is likely to lose its majority in the upper house, exit polls showed after Sunday’s election, potentially heralding political turmoil as a tariff deadline with the United States looms.
