South Coast
Overview
The South Coast (Namhaean, 남해안) is the coastline of the southern Korean Peninsula, collectively referring to the coastal zone and hinterland stretching from the Mokpo–Jindo area of Jeollanam-do in the west to Busan Metropolitan City in the east. Its representative landforms are a highly indented ria coast and an archipelago of thousands of islands; influenced by warm currents, it has a mild climate and abundant fisheries resources. Since ancient times it has functioned as a center of maritime transport and the fisheries and shipbuilding industries, as a stage for naval activity during the Imjin War, and as a representative marine tourism destination.

Geographic Scope and Topography
Administratively, the South Coast encompasses Busan Metropolitan City, southern Gyeongsangnam-do (Changwon, Tongyeong, Geoje, Sacheon, Namhae, Goseong), southern Jeollanam-do (Yeosu, Suncheon, Goheung, Wando, Jindo, Mokpo, Haenam), and parts of Jeju. The proportion of coastline curvature is so high that a substantial portion of the entire Korean Peninsula’s coastline length is concentrated in this region, and islands large and small number in the thousands. Because of terrain in which peninsulas extending far into the sea and bays repeat, natural harbor conditions are good, so ports and harbors developed since ancient times.
Climate and Natural Environment
It has a representative oceanic climate with an annual mean temperature of 13–15℃ and relatively mild winters. In summer it receives heavy rain and lies on paths affected by typhoons. Influenced by the Kuroshio warm current system, subtropical organisms inhabit the area, and ecologically important habitats such as tidal flats, salt marshes, and eelgrass beds are widely distributed. The Hallyeosudo and archipelago areas are designated and protected as marine and coastal national parks.
Industry and Economy
The fisheries sector has a very high share, with active aquaculture of anchovy, oyster, abalone, laver, and wakame, and seafood markets in places such as Tongyeong, Yeosu, and Wando are nationwide distribution hubs. The shipbuilding and offshore plant industries are concentrated in Geoje, Tongyeong, and Changwon, forming a core axis of Korea’s shipbuilding industry. Petrochemicals and steel in the Yeosu–Gwangyang national industrial complexes, and port logistics centered on Busan Port and Gwangyang Port, also account for a large share of the South Coast economy.
History and Culture
It was a stage where the naval forces led by Yi Sun-sin were active in the Battle of Hansan Island and the Battle of Noryang during the Imjin War, and many related relics remain in the Hansan Island, Yeosu, and Namhae areas. As fishing community culture, the South Coast Byeolsingut and boating songs are transmitted as Important Intangible Cultural Properties, and local foods and seafood festivals are active in each region. The island areas of the archipelago have formed a unique living culture and dialect sphere different from the mainland.
Transport and Tourism
The Namhae Expressway and South Coast Tourist Road run along the coast, and KTX, passenger ferries, and land bridges have improved access to island areas. Tongyeong Cable Car, Geoje Haegeumgang and Oedo Botania, Yeosu Odongdo and Dolsan Bridge, Suncheonman Wetland, and Namhae German Village are representative tourism resources. Recently, as demand for marine leisure, yachting, and island tourism has grown, the region is trending toward becoming a stay-type tourist destination.
Recent Trends
In 2024–2025, the South Coast region is changing around mega-regional cooperation and new marine industries. Discussions continue on a South Coast region development plan linking Busan, Gyeongnam, and Jeonnam and on creating a tourism belt, and large-scale offshore wind farm construction is being promoted in places such as Sinan, Yeosu, and Geoje, while a marine energy cluster concept linked to the shipbuilding and equipment industries has emerged. The construction of Gadeokdo New Airport and discussions of a southern metropolitan express railway are cited as variables that could change the South Coast transport network. In addition, the push to inscribe Imjin War naval relics as World Heritage, policies for living population and tourism stays in response to island population decline, and rising water temperatures due to climate change and diversification of aquaculture species are being addressed as major issues.
