京城

Keijō, meaning "capital city," was the Japanese name for the city of Seoul in Korea during the Japanese colonial period, beginning with Japan's forcible annexation of Korea in 1910 and ending with Japan's defeat in World War II in 1945.

The name became the basis for a variety of instutitons, including Keijō Imperial University, which later became the basis for Seoul National University, the most prestigious university in South Korea today.
