Tropical Storm Jangmi brought torrential rain and strong winds to the Tokyo metropolitan area on Wednesday, causing widespread power outages and travel disruptions [1, 2].
The storm's impact on Japan's capital region threatens critical infrastructure and logistics, disrupting one of the world's busiest aviation hubs and leaving thousands of residents without electricity.
The storm made landfall in Wakayama Prefecture [6], triggering flood warnings across the region [6]. In the Tokyo area, aviation was severely impacted, with nearly 880 flights cancelled [4]. Other reports indicate more than 700 flights were grounded [2], while others described the total as hundreds [1].
Utility services suffered significant failures as the storm moved inland. Nearly 60,000 households were left without power [5]. Regional breakdowns include more than 30,000 households without electricity in the Kagoshima region, and around 17,000 outages in Okinawa [7].
Local authorities issued flood warnings as the storm's approach brought heavy precipitation and high winds [6]. The combination of these factors led to the widespread disruption of transport and power grids across the affected prefectures [1, 6].
“Nearly 880 flights cancelled”
The scale of the disruption, affecting both the southern islands and the capital region, demonstrates the storm's broad reach. The variance in flight cancellation data suggests a rapidly evolving situation at Tokyo's airports, while the concentrated power outages in Kagoshima and Okinawa highlight the vulnerability of regional grids to tropical systems.
