The Republic of Korea (South Korea) shares borders to the north with the demilitarized zone (separating it from the Democratic People's Republic of Korea), to the east with the Sea of Japan (East Sea), to the south with the Korea Strait (separating it from Japan) and to the west with the Yellow Sea. There are many islands, bays and peninsulas in the Korea Strait. The volcanic island of Cheju-do lies off the southwest coast. Most of the country consists of hills and mountains and the 30 per cent of flat plain contains the majority of the population and cultivation. Most rivers rise in the mountains to the east, flowing west and south to the Yellow Sea. The Naktong River flows into the Korea Strait near the southern port of Pusan. The eastern coast is rocky and steep with mountains rising from the sea. |
