<h1>Japanese prime minister's party wins supermajority, enabling major shifts in defense, immigration, and security policy.</h1> A more-than-two-thirds lower-house majority gives the governing party an enhanced capacity to enact a right-leaning legislative program focused on revising security and defense policy to allow offensive capabilities, lifting the weapons-export ban, increasing defense spending, and advancing proactive economic and technology investments, alongside tougher immigration, property and anti-espionage measures that observers warn could impinge on civil rights and raise funding and diplomatic-management questions.
