Typhoon 13 is forecast to make a direct hit on Okinawa main island on Aug. 7, 2026 [1].
This simultaneous arrival of two major storms creates a high-risk environment for southern Japan, threatening critical transportation infrastructure and public safety across several prefectures.
Japan is currently surrounded by two simultaneous typhoons, identified as Typhoon 13 and the newly formed Typhoon 15 [2]. Typhoon 15 developed on Aug. 5 [2]. While Typhoon 15 remains a factor, the immediate threat comes from Typhoon 13, which is maintaining a large and strong structure as it moves westward [1, 2].
Forecasters expect maximum instantaneous wind speeds of 55 m/s in Okinawa between Aug. 7 and Aug. 8 [1]. The storm is expected to bring heavy rain and high winds to Okinawa main island, Daito Island, and Kumamoto prefecture [1, 2].
The aviation sector has already begun reacting to the weather warnings. Japan Airlines has cancelled 232 flights [1], while All Nippon Airways has cancelled 244 flights [1]. These disruptions are scheduled between Aug. 6 and Aug. 8.
FNN said that approximately 75,000 people are expected to be affected by these flight cancellations [1].
"A large and strong Typhoon No. 13 is expected to directly hit the main island of Okinawa tomorrow, the 7th," FNN said [1]. The network also said that the presence of both Typhoon 13 and Typhoon 15 puts the region in a precarious position [2].
“Typhoon 13 is forecast to make a direct hit on Okinawa main island on Aug. 7, 2026.”
The simultaneous occurrence of two large typhoons increases the complexity of disaster response and resource allocation for Japanese authorities. When multiple systems are active, the interaction between storms can sometimes alter trajectories or intensify rainfall, elevating the risk of flooding and landslides beyond the impact of a single storm.
