South Iojima native natural environment conservation area

South Iojima native natural environment conservation area is a 367-hectare reserve featuring tropical vegetation and rock formations shaped by ocean currents. The island supports rare plants and animals that evolved in this isolated setting.

The area was established under the Nature Conservation Law to protect natural resources on the island. It forms part of a network of five designated wilderness zones across the Ogasawara archipelago.

Scientists conduct regular research expeditions to document native species and monitor the natural processes within this strictly regulated environment.

Access requires special permits from environmental authorities and is subject to strict rules protecting the environment. Visitors should check requirements in advance, as collecting plants and animals is prohibited and entry restrictions apply.

Researchers conduct regular expeditions to document biodiversity and observe natural processes without human interference. These undisturbed ecosystems provide deep insights into how island habitats and species evolve over time.
