South Korea’s department store market is becoming sharply polarized between dominant Seoul and regional hub stores and underperforming regional outlets. Shinsegae Gangnam and Lotte Department Store Jamsil are each positioned to exceed ₩4 trillion (approximately $2.9 billion) in annual transaction volume this year, which would mark the first time two South Korean department stores cross that threshold in the same year. Shinsegae Gangnam recorded ₩3.6717 trillion last year, while Lotte Jamsil reached ₩3.301 trillion, and both reported or are estimated to have achieved more than 20% growth in the first half of this year. Foreign customer sales at Lotte, Shinsegae and Hyundai Department Store reached a combined ₩1.72 trillion in the first half, with sales at Lotte’s main branch and The Hyundai Seoul rising 140% and 134%, respectively. At the same time, stores including Lotte Masan, Grand Ilsan, Hyundai D-Cube City and Lotte Bundang have closed, while other properties are being sold or considered for redevelopment. Hanwha Galleria is reviewing options including the sale of its 100%-owned Daejeon Timeworld operation, with Lotte Shopping cited as a potential buyer, although no transaction has been confirmed. Timeworld recorded ₩603.2 billion in transaction volume last year, the second-highest among Galleria’s five stores, but that figure declined 18.6% from 2021; separate company figures put its revenue at ₩603.2 billion, down 3.6% year over year. Hanwha plans to spend approximately 900 billion won ($649.8 million) from next year through 2033 to more than double Apgujeong Luxury Hall’s sales floor, while its Daejeon Station Area Complex 2-1 District project remains under feasibility re-evaluation as projected costs rise above 1.6 trillion won. The industry is concentrating capital on destination-style stores and commercial hubs as population decline, aging and youth outmigration constrain regional demand.
