Overview

• NHK projections show the LDP and Komeito won just 75 of 248 Senate seats, falling at least 50 seats short of a majority
• The coalition lost its lower house majority in October 2024, marking the first time since 1955 that it holds neither chamber
• Far-right Sanseito is poised to increase its Senate representation to about 14 seats, up from just two before the vote
• Prime Minister Ishiba has ruled out resignation despite the losses, signaling his intent to govern with a minority legislature
• A fragmented opposition reduces the risk of a no-confidence motion but complicates efforts to pass legislation on tariffs, defense and economic reforms
