Doosan Group is the country’s oldest business organization and ranked 17th in its business hierarchy as of 2023. The group’s headquarters, Doosan Tower, is in Euljiro 6-ga, Jung-gu, Seoul. The company originated from Park Seung-jik Store, established by Park Seung-jik in Jongno-gu, Seoul, in August 1896. In 1946, the company underwent a significant transformation, renaming itself “Doosan Sanghoe.” The name “Doosan” combines “doo” (a traditional Korean unit for measuring grain) and “san” (mountain), symbolizing the company’s philosophy of achieving great heights through collective effort, akin to tiny grains of sand forming a mountain.
