Intensive settlement began in earnest in the late 17th century, when the place was known as Ch'i-hou. Opened in 1863 as a treaty port, subsidiary to the port of Anping farther north on the coast, Kaohsiung became a customs station in 1864 and then gradually became an important port for the southern Taiwan coastal plain.
Kaohsiung's real economic and strategic importance began under the Japanese occupation (1895–1945). The Japanese needed a good port in southern Taiwan to serve those designated areas that were to become a major source of raw materials and food for Japan, and Kaohsiung was chosen. It became the southern terminus of the main north-south railway line, and from 1904 to 1907 extensive harbor works were undertaken. In 1920 the port was given the name Takao and the area became a municipality in 1920.
Before and during World War II it handled a growing share of Taiwan's agricultural exports to Japan, and was also a major base for Japan's campaigns in Southeast Asia and the Pacific, and extremely ambitious plans for the construction of a massive modern port were drawn up. At the same time, it handled a growing share of Taiwan's agricultural exports to Japan. Toward the end of the war, too, the Japanese promoted some industrial development at Kaohsiung, establishing an aluminum industry based on the abundant hydroelectric power produced by the Jih-Yueh Lake project in the mountains.
After it came under Chinese administration in 1945, Kaohsiung developed rapidly. The port, badly damaged in World War II, was restored. It also became a fishing port for boats sailing to Philippine and Indonesian waters. Largely because of its climate, Kaohsiung has overtaken Keelung as Taiwan's major port.
Today as a major international port and industrial city in the southwest of the country, Kaohsiung is the most rapidly developing urban center of Taiwan. With an area of 2,946 km, it has a large natural harbor, with the entrance in recent
