New Ishigaki Airport — Ishigaki, Japan

ISG is New Ishigaki Airport, serving Ishigaki Island in Japan's Okinawa Prefecture, part of the Yaeyama Islands near Taiwan. Opened in 2013 to replace an older, shorter airfield, New Ishigaki Airport enabled larger jet aircraft and significantly expanded tourism capacity to this subtropical destination known for coral reefs, diving, and traditional Ryukyuan culture. ISG connects Ishigaki to major Japanese cities like Tokyo, Osaka, and Naha, as well as some international routes, making it the primary gateway for visitors exploring the surrounding Yaeyama island chain, including Iriomote and Taketomi. The airport's development marked a turning point for regional tourism infrastructure, allowing direct long-haul domestic flights that previously required connections through Naha.
