Northeast Asia, sometimes called Northeastern Asia or Northeast Eurasia, is a geographical subregion of Asia. Its northeastern landmass and islands are bounded by the North Pacific Ocean.
The term Northeast Asia was popularized during the 1930s by American historian and political scientist Robert Kerner. Under Kerner's definition, "Northeast Asia" includes the Japanese archipelago, the Korean peninsula, the Mongolian Plateau, the Northeast China Plain, and the mountainous regions of the Russian Far East, stretching from the Lena River in the west to the Pacific Ocean in the east.
