Senagajima Sunset Park Observatory sits on Senaga Island south of Naha Airport, where you can watch passenger planes landing alongside the city of Naha. The view takes in aircraft moving between the two runways, and on clear days the sea at sunset. It is close to Sunset Park's fourth parking lot, and the observatory parking lot is free, though reaching the beach side requires climbing four to five flights of stairs. There is no shelter from sudden squalls or strong winds.
