The Kuroshio Current is an ocean current found in the western Pacific Ocean off the east coast of Taiwan and flowing northeastward past Japan, where it merges with the easterly drift of the North Pacific Current. It is analogous to the Gulf Stream in the Atlantic Ocean, transporting warm, tropical water northward towards the polar region. It's also sometimes known as the "Black Stream"—an allusion to the deep blue of its water.

Its northern counterpart is the North Pacific Current.

Its eastern counterpart is the California Current.

Its southern counterpart is the North Equatorial Current.
