North Iwo Jima

North Iwo Jima is a volcanic island in Ogasawara Village featuring steep cliffs and dark rock formations shaped by intense geological activity. The landscape shows the raw, dramatic results of ongoing volcanic processes that continue to reshape the terrain.

The island became part of Tokyo's administrative region during Japan's territorial expansion in the late 1800s and has since attracted scientific attention. Its ongoing geological activity has made it valuable for studying volcanic processes and environmental changes.

Scientists regularly conduct research expeditions to North Iwo Jima to study its volcanic formations and document the changes in local marine ecosystems.

Access requires special permits from Japanese authorities, and visits are typically limited to research expeditions rather than general tourism. The remote location and protected status mean that only authorized travelers can reach the island.

The island continuously releases sulfur emissions that create unusual mineral deposits in the surrounding waters. This chemical activity makes the area particularly valuable for marine researchers studying geothermal environments.
