The modern postal system was first introduced in 1884, but was actually implemented after the Gabo Reform of 1894, with post offices set up in various parts of the country.

In 1895, the Incheon office was located inside the building of the shipping firm Yiun-sa in Gyeong-dong, Jung-gu, and moved to Nae-dong in 1898.

It was merged into the Japanese-owned Incheon post office after the Japanese Resident-General of Korea was established by the Protectorate Treaty between Korea and Japan, concluded in 1905. When Korea was annexed by Japan, it came under the jurisdiction of the Japanese Government-General of Korea and later became the Incheon post office after the country’s independence.

The building, completed in 1923, has an eclectic style that blends the Western and Japanese styles that were in fashion at the time, and is a two-story building with bricks stacked on top of granite and dressed in a rough manner, making it look like a stylobate.

Large columns were installed on either side of the entrance, and the main entrance protruded to the corner facing the intersection and was constructed in a straight line.

During the Korean War, some parts of the roof were destroyed and partially repaired. It is now used as the Jung-dong post office.
