Shinsegae is also famous for its long history. The main branch of Shinsegae is the oldest department store in Korea. The main building of the store was opened in 1930 as the Gyeongseong branch of Mitsukoshi, a Japanese department store franchise; Korea was occupied by the Japanese Empire at the time. The store was acquired in 1945 by the late founder of Samsung group, Lee Byung-chull, and renamed Donghwa Department Store. After the Korean War (1950–1953) began, it was used for several years as a post exchange by the American army. In 1963, the store was given the name Shinsegae. The old building is currently used as a luxury shopping venue.
Shinsegae was the first credit card company in South Korea. They issued its own charge card from 1967 to 2000. In 2000, Shinsegae sold its credit card division to KorAm Bank, which was later acquired by Citibank Korea.
