Danjo Guntō is a small group of islands administered by Nagasaki Prefecture in western Japan, situated off the coast of Kyushu and noted for steep coasts and rich marine life.

The islands are largely uninhabited and are important for seabird nesting and nearshore marine ecosystems; they are visited only infrequently and access is often limited to protect habitat.

Charting, naming and limited human use date from regional maritime history, while contemporary management focuses on conservation of seabirds and marine resources.

Geographically the islands lie in the East China Sea to the west of Kyushu and are part of Nagasaki Prefecture’s offshore island groups.

  • Wildlife protection: The island group is noted for seabird colonies and marine biodiversity and is often subject to access controls to protect wildlife.
