South Korea, officially known as the Republic of Korea is an East Asian country occupying the southern half of the Korean Peninsula. To the north, it is bordered by North Korea (Democratic People's Republic of Korea), with which it was united until 1945. To the west, across the Yellow Sea, lies China and to the southeast, across the Korea Strait, lies Japan. The Republic of Korea in Korean means "The Great Nation of the Korean People" and is sometimes referred to as the "Land of the Morning Calm", originating from the peaceful Joseon Dynasty. The capital and largest city of South Korea is Seoul, the world's 2nd largest metropolitan city. The official language of South Korea is Korean and is currently the 10th most spoken language in the world.
South Korea occupies the southern portion of the Korean Peninsula, which extends some 680 miles (1,100 km) from the Asian mainland. This mountainous peninsula is flanked by the Yellow Sea to the west, and the Sea of Japan (East Sea) to the east. Its southern tip lies on the Korea Strait and the East China Sea.
The country's total area is 38,462.49 square miles (99,617.39 km²).
South Korea can be divided into four general regions: an eastern region of high mountain ranges and narrow coastal plains; a western region of broad coastal plains, river basins, and rolling hills; a southwestern region of mountains and valleys; and a southeastern region dominated by the broad basin of the Nakdong River.
South Korea's land is mostly mountainous, most of which is not arable. Lowlands, located primarily in the west and southeast, constitute only 30% of the total land area. |
