Okushiri Airport — Okushiri Island, Japan

Okushiri Airport, coded OIR, serves Okushiri Island, a small island off the southwest coast of Hokkaido, Japan. The island became internationally known following the devastating 1993 Hokkaido earthquake and tsunami, which caused significant loss of life and led to major rebuilding efforts, including improvements to local infrastructure such as the airport. OIR provides a vital air link between Okushiri and the Hokkaido mainland, supporting the island's fishing-based economy and limited tourism industry. Given the island's remote location and reliance on ferry connections that can be disrupted by weather, Okushiri Airport plays an important supplementary role in ensuring residents have reliable access to medical care, supplies, and travel options. The airport remains a modest but essential piece of infrastructure for this small Hokkaido community.
