(OKINAWA, JAPAN) — Authorities effectively closed Naha Airport for the day on June 1 as Typhoon No. 6 approached Okinawa, while airlines canceled 405 flights across Japan.

Air service across Okinawa halted as all flights to and from Naha, Miyako, and Ishigaki airports were canceled on June 1. The shutdown left the prefecture’s main air gateways offline as the storm drew nearest to the islands.

Japan Airlines canceled 71 flights on June 1, and All Nippon Airways canceled 104 flights the same day. JAL and ANA had also already announced more than 130 additional cancellations for June 2, extending the disruption beyond the first day of the storm’s impact.

Ground and sea transport also stopped. Okinawa’s route buses suspended service, the Okinawa Urban Monorail suspended operations, and all ferry services linking Okinawa Island, Miyakojima, and nearby islands were suspended.

The shutdowns cut across the transport network at the same time the typhoon was forecast to pass closest to Okinawa on June 1. Forecasts then showed the system moving toward western Japan.

The closest approach to the Kansai region was expected between the night of June 2 and the early hours of June 3. That trajectory put the storm on a path from the far southwest toward one of Japan’s most densely traveled regions.

Weather data in the broadcast transcript described the typhoon as having a central pressure of 975 hectopascals. It carried maximum sustained winds of 30 meters per second and maximum instantaneous gusts of 45 meters per second.

Forecasters also expected heavy rain, storm surge, and violent seas in Okinawa. Those conditions affected not only aviation but the wider movement of people and goods across islands that depend on short flights, ferries, buses, and the monorail.

The closure of Naha Airport carried particular weight because the airport serves as Okinawa’s main air hub. With all flights at Naha canceled for the day, the interruption reached far beyond a single terminal and spread through domestic schedules elsewhere in Japan.

The total of 405 flights canceled nationwide underscored that reach. Within that broader figure, the largest named airline disruptions came from ANA’s 104 flights and JAL’s 71 flights, while the remaining cancellations were spread across other operators and routes.

Miyako and Ishigaki, which rely heavily on air links with the rest of Okinawa and mainland Japan, also saw complete flight stoppages for the day. Ferry suspensions linking Okinawa Island, Miyakojima, and nearby islands removed another set of connections as sea conditions worsened.

On land, the suspension of route buses and the Okinawa Urban Monorail narrowed options within Okinawa itself. Travelers who had already reached the prefecture faced a transport system that had largely shut down at once, from airport runways to city rail lines and inter-island vessels.

Airlines moved quickly into a second day of cancellations even before the storm completed its closest pass to Okinawa. The more than 130 additional cancellations announced for June 2 by JAL and ANA pointed to continued disruption as the typhoon advanced toward western Japan.

The sequence of closures showed how broadly Typhoon No. 6 was affecting the region. Airports at Naha, Miyako, and Ishigaki stopped flights, buses and monorail stopped running, ferry routes shut down, and the storm then turned toward western Japan with the Kansai area in its projected path by the night of June 2 into the early hours of June 3.
