The Mukojima Islands are a small group of islands in the Ogasawara or Bonin archipelago, administered as part of Tokyo Prefecture. They form one of the remote island groups in the Pacific west of the main Ogasawara clusters.

Small and largely uninhabited, the islands are noted for seabird colonies, endemic plant species and surrounding coral reefs. Shorelines and coastal habitats are the main features of interest rather than visitor facilities.

The islands were incorporated administratively into Tokyo with the other Bonin Islands and are part of the wider Ogasawara natural area that received UNESCO World Heritage recognition in 2011. Human presence has historically been minimal and the islands remain largely undeveloped.

Geographically the group sits in the northwestern Pacific as part of the Bonin chain, roughly 1,000 kilometers south of mainland Tokyo. The nearest inhabited Bonin islands lie to the south and southwest; the surrounding seas are open ocean with coral reef outcrops.

  • World Heritage status: Included in the Ogasawara (Bonin) Islands World Heritage inscription in 2011 for its endemic flora and seabird colonies.
  • Access: Largely uninhabited and remote, landing is often restricted or requires permission; access is typically by private boat or organized expedition.
