Jakarta, officially the Special Region of Jakarta, previously called the Special Capital Region of Jakarta, is the de facto capital and largest city of Indonesia and an autonomous region with administrative status equivalent to a province. Located on the northwest coast of Java, the world’s most populous island, the city borders the provinces of West Java and Banten and faces the Java Sea to the north. Although Jakarta covers about 662 square kilometres, the wider Jakarta metropolitan area—commonly known as Greater Jakarta—is one of the largest urban agglomerations in the world. The city serves as Indonesia’s political, economic, and cultural centre and hosts numerous national institutions, corporate headquarters, and the secretariat of the Association of Southeast Asian Nations (ASEAN).
