Kitadaito Airport — Kitadaitōjima, Japan

Kitadaito Airport lies on the small, remote island of Kitadaitōjima, part of the Daitō Islands in Japan's Okinawa Prefecture, far out in the Pacific east of the main Okinawan islands. At an elevation of about 80 feet, it has a single asphalt runway near 4,921 feet, providing the isolated island community with an air link that is essential given its distance from anywhere else. The Daitō Islands are among the most far-flung parts of Japan, tiny specks of land surrounded by open ocean. The KTD code identifies this field, whose flights connect a few hundred residents to Okinawa's main island, making aviation a genuine lifeline for daily life on Kitadaitō.
