Tokunoshima Airport — Amagi, Japan

Tokunoshima Airport, coded TKN, serves Tokunoshima Island in Japan's Kagoshima Prefecture, part of the Amami archipelago in the East China Sea. The airport connects the island to Kagoshima and Amami Oshima via domestic flights, supporting a small population along with sugarcane farming and traditional bullfighting culture unique to the island. Tokunoshima's subtropical climate and coral reef surroundings attract modest ecotourism interest, and TKN provides essential access given the island's remote location far from mainland Japan. The airport's single short runway reflects the limited scale of operations typical of Japan's outlying island airfields, yet it remains a vital lifeline for residents dependent on air transport for travel and supplies.
