Japan’s southern island of Kyushu is facing a severe meteorological crisis as record-breaking torrential rains have led to catastrophic floods and landslides, causing widespread travel disruptions and endangering lives during the peak Bon holiday travel season.
Extent of the Rainfall & Weather Warnings
On August 11, 2025, torrential downpours swept across Kyushu, with Kumamoto Prefecture alone registering more than 40 cm (15.7 inches) of rainfall within just 24 hours—the highest rainfall alert ever recorded there. The Japan Meteorological Agency issued its highest-level warning for Kumamoto, later downgraded as the storm system began its eastward shift. Yet, a lower-tier alert remained in place for western Japan as additional heavy showers were anticipated.
In Tamana City, Kumamoto, an astonishing 370 mm (37 cm) of rain fell in a mere six hours—roughly double the region’s August monthly average—prompting authorities to sound the highest-possible danger alerts and warn of imminent disaster risk.
Human & Infrastructure Toll
Authorities have issued evacuation advisories for tens of thousands of residents across multiple prefectures, including Kumamoto, Kagoshima, and Fukuoka. In some reports, up to 3 million people were under evacuation notices as a result of rising waters and unstable hillsides.
Numerous tragedies have been reported: a woman missing since Friday in Kagoshima was found deceased, and in Kumamoto, a man discovered with no vital signs after a mudslide struck his vehicle. Other victims remain missing, swept away by swollen rivers or caught in landsliding debris. In addition, about 6,000 households in Kumamoto were left without power, although restoration efforts brought electricity back to nearly half later in the day.
The downpour has also severely damaged infrastructure: roads submerged under knee- to waist-deep waters, bridges compromised, and communities cut off by landslides. In Kagoshima City, flooding forced shopkeepers to clean up damaged goods and equipment, with many unsure when they can reopen.
Travel & Tourism Disruptions Amid Bon Holiday Rush
This calamity has arrived amid Japan’s Bon holiday, a traditional period when many Japanese travel to reunite with family. A combination of bullet train suspensions, canceled local trains, road closures, and flood-damaged infrastructure has thrown travel plans into chaos. Bullet trains between Kagoshima and Hakata were halted on August 11, with ripple effects spreading as far east as Honshu.
With mass transit limited, roads impassable, and power outages ongoing, both residents and tourists are stranded, placing immense strain on emergency relief operations.
Government Mobilization & Community Resilience
Prime Minister Shigeru Ishiba has mobilized a national emergency response, coordinating rescue and relief efforts across affected areas. Defense forces were dispatched to impacted regions such as Kagoshima to deliver critical supplies like fresh water, while emergency teams worked around the clock to search for missing persons and evacuate vulnerable populations.
Local and national agencies are combining resources to secure shelters, clear roads, and restore vital services. Communities and authorities alike remain on high alert, as more rain is expected and ground conditions remain dangerously unstable.
Outlook & Tourism Recovery
Although this disaster has plunged Kyushu into crisis, resilient recovery efforts are already under way. As floodwaters recede, restoration of transport networks and essential infrastructure will be critical steps toward reviving tourism and economic activity in the region.
For those planning future visits to Kyushu, consider monitoring weather updates, checking advisories from Japan’s Ministry of Transport, local prefectural sites, and the Japan Meteorological Agency. While some attractions may reopen in the near term, infrastructure repairs may delay full return to regular tourism operations.
Kyushu’s hot springs, historic sites, and scenic landscapes remain undiminished—but the paths to them may take time to become fully accessible again. The steadfast spirit of local communities, backed by coordinated government support, stands as a beacon of hope through this challenging time.
In Summary: Devastating rainfall across Kyushu has triggered record-breaking floods and landslides, severely impacting travel and tourism during the Bon holiday. Authorities continue rescue operations and evacuations, while infrastructure damage poses a prolonged recovery challenge.
