Mukōjima

Mukōjima features rocky shores surrounded by coral reefs and dense vegetation that provides habitat for diverse plant and animal species adapted over millions of years since its volcanic formation.

The island emerged approximately 48 million years ago through volcanic activity caused by tectonic movements when the Pacific Plate subducted beneath the Philippine Sea Plate, creating its distinctive geological landscape.

The island maintains traditional Japanese conservation practices and hosts annual ceremonies celebrating the natural environment, emphasizing sustainable interaction between humans and the fragile ecosystem through educational programs.

Visitors can access Mukōjima through guided tours from neighboring islands like Chichijima during summer months, but must adhere to strict environmental guidelines to protect the fragile habitats.

The island contains rare boninite volcanic rock formations that share mineral compositions similar to meteorites, making it one of the few places on Earth where this geological phenomenon can be observed.
