Tsushima Airport — Tsushima, Japan

Tsushima Airport serves Tsushima Island, situated in the strait between Japan and South Korea, making it one of Japan's most geographically distinctive island territories. TSJ connects Tsushima to Fukuoka and Nagasaki on the Japanese mainland via short domestic flights, essential given the island's separation from Kyushu by open water. Tsushima has long served as a historical bridge between Japan and Korea, with the island's proximity to South Korea also making it a popular day-trip destination for South Korean tourists arriving by ferry. The airport supports both this cross-border tourism dynamic and the needs of Tsushima's resident population, who rely on air links for faster access to mainland services.
