Miyake-jimaMiyake-jima is a volcanic island in the Izu Islands chain administered by Tokyo Prefecture, known for its active Mount Oyama and rugged coastal scenery. The island’s volcanic activity has shaped both its landscape and modern community arrangements.
Hiking to Mount Oyama, visiting geothermal sites and diving off sheltered coves are primary visitor activities; services are concentrated in the main village where the ferry and small airport land. The island experienced a significant volcanic episode in 2000 that produced elevated sulfur dioxide emissions and required temporary evacuation of residents; phased returns were organized once conditions allowed.
Miyake-jima sits in the Philippine Sea as part of the Izu archipelago, several hundred kilometres south of central Tokyo, and is reached by scheduled ferry or regional flights depending on the season.
