Diaoyudaoite was found in a heavy mineral fraction of the surface layer of sea-floor muds taken offshore at about 1500m water depth, roughly 200 km northeast of Taiwan. Named after the Chinese name for the Senkaku islands. The natural origin of this material (diaoyudaoite, corundum, eskolaite, chromium, carlsbergite) is in doubt.

The grid reference marks the approximate sampling locality, as given by Shen et al. (1986).
