Oshima Airport — Izu Oshima, Japan

Oshima Airport, coded OIM, serves Izu Oshima, a volcanic island in the Izu archipelago south of Tokyo, Japan. The island is dominated by Mount Mihara, an active volcano that has shaped both the island's dramatic landscape and its tourism appeal, drawing hikers and nature enthusiasts. OIM connects Izu Oshima to Tokyo and other nearby islands, offering an alternative to the ferry services that also serve the island. Given the volcanic activity in the region, including a significant eruption in 1986 that required island-wide evacuation, air access through Oshima Airport has practical significance for both routine travel and emergency response planning. The airport supports small aircraft operations suited to the island's modest passenger demand and its role as a gateway to volcanic tourism.
