North Iwo Jima

North Iwo Jima rises 792 meters above sea level, featuring steep cliffs and black volcanic rocks that form its distinctive geological structure.

The island became part of Tokyo's administrative region during Japan's territorial expansion in the late 19th century, marking its integration into modern Japan.

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

Access to North Iwo Jima requires special permits from Japanese authorities, and transportation is limited to scheduled research and monitoring vessels.

The island's geological activity produces continuous sulfur emissions, creating mineral deposits that give the surrounding waters a distinctive composition.
