The Republic of Korea (South Korea) is a peninsula that shares borders to the north with the demilitarised 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 and bays in the Korea Strait, including the largest, the volcanic island of Jeju-do, which lies off the southwest coast and is also home to South Korea's highest mountain, Mount Halla, at 1,950m (6,397ft). Most of the country consists of hills and mountains with the 30% of flat plain home to 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 Busan, Korea's second largest city after Seoul. The eastern coast is rocky and steep with mountains rising from the sea.
