How early should I arrive at Kumejima Airport?

Kumejima Airport (UEO) serves the island town of Kumejima in Okinawa Prefecture and operates as a small regional airport with a single terminal handling both domestic arrivals (到着) and departures (出発). It is primarily served by local carriers such as Ryukyu Air Commuter and Japan Airlines subsidiaries, offering frequent connections to Naha and other nearby islands, plus seasonal flights from larger Japanese cities. Travelers can check the online flight board (オンラインフライトボード) for real-time schedules, note limited ground services and rental options, and plan extra time for inter-island transfers and weather-related adjustments.
