Typhoon 6 entered the violent-wind zone of Okinawa on May 31, bringing record-breaking rainfall and strong winds to the region [1].
The storm's arrival disrupts critical transportation links and threatens infrastructure on the main island and in Naha city. Because Okinawa relies heavily on air travel for connectivity to mainland Japan, the total suspension of major airline services creates a significant logistical bottleneck.
The system was reported to have entered the violent-wind zone at 10:00 JST on May 31 [1]. At that time, the typhoon was moving west-north-west at approximately 20 km per hour [1]. This movement brought warm, moist air into the region, which produced the heavy rainfall and intensifying winds observed across the prefecture [4, 5].
Both ANA and JAL cancelled all flights to Okinawa in response to the deteriorating weather conditions [3]. The storm is expected to affect Okinawa and Amami from May 31 to June 1 [2].
Local authorities warned of the potential for record-level rain as the system continued to intensify while moving north-westward [4, 5]. The impact has been most severe on the main island and within the Naha city area, where the combination of wind and rain posed the highest risk to residents [2, 3].
“All ANA and JAL flights to Okinawa were cancelled.”
The total cancellation of flights by Japan's two largest carriers indicates a high-severity weather event. The timing of Typhoon 6, coinciding with the transition into June, highlights the volatility of the early typhoon season in the Ryukyu Islands, where record-breaking precipitation can lead to immediate flash flooding and landslides in urban centers like Naha.
