Description ▣ Jeju, South Korea — what kind of city is it? Jeju Island, our country's beautiful island filled with sights, delicious food, and fun activities everywhere you look! Recognized as one of the world's premier tourist destinations, Jeju is also home to over 660,000 residents who call it their everyday living space. As the largest island in South Korea, Jeju is quite sizable even by Asian standards — in fact, the entire territory of Singapore, a major Asian city-state, is only about one-third the size of Jeju Island. In recognition of both its scale and its unique status as an island, Jeju was elevated in 2006 to become South Korea's first Special Self-Governing Province. As a result, Jeju enjoys independent administrative authority and even has its own special autonomous police force, giving it a distinctive administrative system unlike any other region in the country. Rising majestically at the island's center is Hallasan, standing at about 1,950 meters — the tallest mountain in South Korea. Centered around this volcanic peak, Jeju Island's landscape holds tremendous ecological value. The island boasts such diverse and unique volcanic terrain that it could rightfully be called a 'volcanic museum.' Thanks to these remarkable features, Jeju was designated a Biosphere Reserve in 2002, inscribed as a UNESCO World Natural Heritage Site in 2007, and certified as a UNESCO Global Geopark in 2010 — achieving the remarkable distinction of a UNESCO Triple Crown. ▣ Inside the Book The World City Exploration Comics: History Knowledge series inserts an informational page connected to the story at the end of each comic chapter, effectively delivering essential knowledge about the history and culture of world cities. Treasure Hunt in Jeju 1 features a 'Jeju at a Glance' page that uses maps, photos, and text to introduce important locations across the island, along with a 'Jeju Basics' page that broadly covers the island's characteristics, climate, and volcanic activity. The book also includes a 'Jeju History' page exploring the island's rich and varied past, including the mystical legend of Grandmother Seolmundae and the founding myth of the ancient Tamna kingdom. A 'Jeju Travel' section highlights three must-visit destinations: Jeju Dongmun Market, a beloved traditional market that has been part of local life since just after Korea's liberation in 1945; the National Museum of Jeju, where visitors can learn all about the island in one place; and the Lee Jung-seob Art Gallery, where visitors can feel the artistic spirit of painter Lee Jung-seob. Rounding out the book is a 'Jeju Culture' page that introduces local specialties like mongguk (pork and seaweed soup) and dombe-gogi (sliced boiled pork), fresh seafood, and Jeju's famous citrus fruits like hallabong and cheonhyehyang. Finally, a Jeju-themed amusement park section with hidden picture puzzles and spot-the-difference games adds an extra layer of fun.
