An uninhabited volcanic island at the northern edge of the Bonin Islands, Muko-jima represents a pristine natural landscape protected within Japan’s UNESCO World Heritage Site and national park system.
At a glance
Muko-jima forms part of the Mukojima Islands, the northernmost group within the Bonin Islands archipelago. The island itself remains uninhabited, its ecology and geology preserved under strict environmental protection. The surrounding waters and reefs contribute to one of Japan’s most significant marine and terrestrial heritage zones.
History
The Mukojima Islands were historically known to Western navigators as the Parry Group. Today, Muko-jima exists primarily as a natural reserve, its isolation and lack of permanent settlement allowing its ecosystems to develop without human disturbance.
What you see
As an uninhabited natural site, Muko-jima offers volcanic geology and endemic flora characteristic of the remote Bonin Islands. Surrounding reefs create a significant marine environment.
Cultural significance
