Shimojishima Airport — Miyakojima, Japan

Shimojishima Airport, designated SHI, sits on Shimoji Island within Japan's Okinawa Prefecture, part of the Miyako Islands chain. Originally built with an unusually long runway intended for pilot training by international airlines, the airport has since transitioned toward serving low-cost carriers and tourists drawn to the region's turquoise waters and coral reefs. SHI provides connections to mainland Japan and other Okinawan islands, supporting the growing tourism economy of the Miyako area. The surrounding island scenery, including nearby bridges connecting Shimoji to Irabu and Miyako Islands, has made this airport increasingly popular among travelers seeking a quieter, scenic alternative to Okinawa's more crowded destinations.
