East Asia is a subregion of Asia that can be defined in either geographical4 or cultural5 terms. Geographically, it covers about 12,000,000 km², or about 28 percent of the Asian continent, about 15 percent bigger than the area of Europe. More than 1.5 billion people, about 40 percent of the population of Asia or a quarter of all the people in the world, live in geographic East Asia, which is about twice the population of Europe. The region is one of the world's most crowded places. The population density of East Asia, 131 per km², is about three times the world average of 45 per km².6
East Asia and Eastern Asia (the latter form preferred by the United Nations) are both more modern terms for the traditional name the Far East7, which describes the region's geographical position in relation to Europe rather than its location within Asia. However, in contrast to the United Nations definition, East Asia commonly is used to refer to the eastern part of Asia, as the term implies.

Some consider the following countries or regions as part of East Asia, while others do not.citation needed Disagreements hinge on the difference between the cultural and geographic definitions of the term. Political perspective is also an important factor. In descending order in terms of the frequency with which they are described as East Asian:citation needed
Mongolia (considered either East Asia or Central Asia—here culture and/or geography may be at issue)
Vietnam (considered either East Asia or Southeast Asia—here the primary question is geographic)
Russian Far East (considered either East Asia or North Asia—here the primary question is political, with culture and geography also at issue)
In infrequent circumstances, the term East Asia is purposefully used to include all countries in Southeast Asia, especially when used in dualism with the term West Asia, the latter of which is then used to include those regions commonly considered West Asia, Central Asia and Southwest Asia.citation needed
