Why It Matters
Scientists note that a warmer atmosphere holds more moisture, intensifying rainfall, while the “super El Niño” has raised sea-surface temperatures, contributing to the storm’s strength. The event highlights Japan’s exposure to climate-amplified extreme weather and the strain on disaster-response systems.
What’s Next
Search and rescue operations for the missing continue, and the JMA monitors for additional heavy rain. No new evacuation orders have been announced as of September 23, and authorities are working to restore power and transport infrastructure over the coming weeks.
