Sado Airport — Sado, Japan

Sado Airport is a small airfield located on Sado Island off the coast of Niigata Prefecture, Japan, in the Sea of Japan. Sado Island is renowned for its rich cultural heritage, including former gold mines, traditional folk performances, and populations of the endangered Japanese crested ibis. The airport historically supported limited commercial flights connecting the island to mainland Japan, though service levels have fluctuated over the years due to low passenger demand and competition from ferry services. SDS remains an alternative gateway for tourists and residents seeking faster travel than the boat crossing from Niigata City. The airfield's short runway limits it to smaller aircraft types typical of regional island-hopping routes in Japan.
