Lotte Co., Ltd is an East Asian conglomerate and one of the largest food and shopping groups in South Korea and Japan. Originally established in 1948 in Tokyo by a Korean businessman, Lotte started trading in Korea after the normalisation of Japan-Korean relations in 1965.

Unusually for a large Korean chaebol, Lotte's headquarters are in Shinjuku, Tokyo compared to Seoul, which is typical of other chaebol groups.
