"Due to the special terrain of Eiko, Umibutsu International utilised 2 neighbouring islands on the coast, with one of the runway built on the smaller island and another one of the runway plus the terminal on the larger island, meaning that planes landing on the second runway have to pass through a narrow bridge to access the terminal -- a view considered quite astonishing but not that much as the approach of Al Tak. Large airliners often land here but smaller airplanes may be redirected to airfields around Eiko."
