Rishiri Airport — Rishiri, Japan

Rishiri Airport serves Rishiri Island, a small volcanic island off the northern coast of Hokkaido, Japan, known for the dramatic cone-shaped Mount Rishiri and its hiking and seafood tourism. RIS handles domestic flights connecting the island to Sapporo and other Hokkaido destinations, though service has historically been seasonal and limited due to the island's small year-round population and challenging weather, including frequent fog that can disrupt operations. Rishiri's economy relies heavily on fishing, particularly kelp harvesting, alongside a growing tourism sector centered on outdoor activities. RIS remains a small but vital air link for islanders and visitors who would otherwise depend on longer ferry crossings from the Hokkaido mainland.
