Typhoon 15 is moving in an unusual east-to-west direction across Japan on Tuesday, Aug. 11 [1].
The storm's rare trajectory is disrupting the Obon holiday period, one of Japan's busiest travel windows. This "reverse" track increases the storm's impact on infrastructure and tourism as millions of people travel to visit ancestral graves and family homes.
Heavy rain began falling around 11 a.m. in Kushiro, Hokkaido [2]. Other regions under alert include the Kanto Pacific coast, Miyagi, Aomori, and Iwate [1]. Local authorities have responded by closing beaches to prevent accidents as the system moves across the archipelago [1].
Air travel has been severely impacted by the weather. At Haneda Airport, travelers faced difficulties with digital re-booking systems as flights were cancelled. One traveler whose 4:30 p.m. flight to Saga was cancelled said they came to the airport counter because they could not use the online booking buttons [3].
Officials are urging caution even in areas far from the center of the storm. The unusual path of Typhoon 15 means that regions typically less susceptible to specific storm patterns may face unexpected flooding and wind damage [1].
Flight cancellations have forced many passengers to seek manual re-booking at airport counters [3]. The combination of the holiday rush and the storm's erratic path has created significant congestion at major transport hubs [1].
“The storm is following a rare “reverse” trajectory, moving from east to west.”
The 'reverse' movement of Typhoon 15 is a meteorological anomaly that complicates standard emergency preparedness. Because the storm is hitting during Obon, the intersection of peak domestic travel and unpredictable weather creates a high-risk scenario for transportation bottlenecks and public safety lapses across both northern and southern Japan.
