The Jakota Triangle is an East Asian region comprising 3 countries: , , and . The concept originated with Harm de Blij and it has become popularized in the many editions of Geography: Realms, Regions and Concepts, first appearing in the 8th edition, published in 1997. The term triangle was inspired by the three-sided figure defined by the 3 capital cities of the region: , Seoul and Taipei. But the Jakota triangle is unified by more than its three-cornered geometry. This group of East Asian states shares high population density, a high level of urbanization, rapid growth in manufacturing in spite of its dependence on imported raw materials, and lingering geopolitical problems that may be traced to the end of World War II.
