Jangsaengpo (Korean: 장생포) is a port located in Nam District, Ulsan, South Korea.
The Jangsaengpo whaling originates from the establishment of the Pacific Fisheries Co., Ltd. by the Russian Emperor, Nicholas II in 1891.
However, as Japan monopolized the whaling business after the victory of the Russo-Japanese War and overhauled whaling stations nationwide, Jangsaengpo drew attention as the center of the whaling business.
After liberation, Korean people jointly took over the Japanese-run company and changed its name to Joseon Whaling Co., Ltd.
However, careless whaling reduced the catch and some species were even in danger of extinction by 1980.
