Geography of South Korea
Overview of the geography of South Korea

South Korea is located in East Asia, on the southern portion of the Korean Peninsula located out from the far east of the Asian landmass. The only country that shares a land border with South Korea is North Korea, lying to the north with 238 kilometres (148 mi) of the border running along the Korean Demilitarized Zone. South Korea is mostly surrounded by water and has 2,413 kilometres (1,499 mi) of coastline along three seas: to the west is the Yellow Sea (called Sohae Korean: 서해; Hanja: 西海; in South Korea, literally means "west sea"), to the south is the East China Sea, and to the east is the Sea of Japan (called Donghae Korean: 동해; Hanja: 東海; in South Korea, literally means "east sea"). Geographically, South Korea's landmass is approximately 100,472.4 square kilometres (38,792.6 mi2). The approximate coordinates are 37° North, 128° East.
Land area and borders
The Korean Peninsula extends southward from the northeast part of the Asian continental landmass. The Japanese islands of Honshū and Kyūshū are located some 200 kilometers (124 miles) to the southeast across the Korea Strait, and the Shandong Peninsula of China lies 190 kilometers to the west. The west coast of the peninsula is bordered by the Korea Bay to the north and the Yellow Sea and Korea Strait to the south; the east coast is bordered by the East Sea. The 8,640-kilometer coastline is highly indented. Some 3,579 islands lie adjacent to the peninsula, most found along the south and west coasts.
Begin with the source’s own compact description: “Geography of South Korea” is overview of the geography of South Korea. The dossier treats that line as a proposition to test through Geography, South and Korea, not as a finished interpretation.
Why this record matters
The phrase “overview of the geography of South Korea” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 13, 2026. The linked authority identifier is Q718476. Authority coordinates are 36.000, 128.000. None of the 1 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
