Starfield COEX Mall is an underground shopping center in Samseong-dong, Gangnam-gu, Seoul, spanning approximately 154,000 square meters on a single level, recognized as the worlds largest underground mall. Integrated within the COEX complex, it connects directly to Samseong Station on Line 2 and Bongeunsa Station on Line 9 of the Seoul Metro, providing excellent accessibility for over 1.5 million daily subway passengers in the area.
The property features over 300 retail outlets, including fashion brands, electronics, and lifestyle stores, alongside two food courts with diverse dining options from local Korean cuisine to international chains. Entertainment anchors include the COEX Aquarium housing 40,000 marine creatures, MegaBox cinema with multiple screens, and the iconic Starfield Library displaying 50,000 books as a cultural hub for events and reading.
Managed by Shinsegae and owned by the Korea International Trade Association, the mall operates daily from 10:30 AM to 10:00 PM with free entry. In the context of Seouls retail market, it holds a strong position in the premium Gangnam district, benefiting from the citys tourism rebound with 16.37 million inbound visitors in 2024, representing 94% of 2019 levels.
Leasing advantages include high visibility through convention center synergies, drawing business travelers and tourists, and a balanced tenant mix that supports cross-traffic between shopping, exhibitions, and leisure. However, challenges arise from Gangnams 15.4% vacancy rate in Q4 2024, reflecting slower post-pandemic recovery compared to tourist-heavy areas like Myeongdong, potential saturation in entertainment categories, and competition from newer integrated developments.
Operational quality remains high with recent renovations enhancing flow and appeal, but aging underground infrastructure may require ongoing maintenance.
Overall, it suits retailers targeting affluent locals aged 25-45, young professionals, and international visitors seeking experiential retail in a convenient urban setting.

Insights
Demographics and Footfall
The primary demographic comprises affluent urban professionals and families in Gangnam, with median household incomes exceeding KRW 100 million annually, alongside a growing influx of international tourists from China, Japan, and the US, driven by K-culture appeal. Footfall benefits from the COEX complexes role as a MICE hub, estimating 40-50 million annual visitors pre-pandemic, with 2024 recovery showing subway traffic in Gangnam exceeding 2019 levels in peak periods. This supports strong performance for experiential and F&B tenants, though seasonal dips occur outside convention events, and competition from nearby high streets like Apgujeong dilutes pure mall traffic.
Occupancy and Rent Levels
Occupancy in Seouls mall sector hovers around 85-90% for prime assets like COEX, though Gangnam high street vacancy at 15.4% in Q4 2024 indicates selective leasing pressures. Average rents for mall spaces range from KRW 150,000 to 250,000 per square meter annually, often structured as 10-15% of gross sales plus base, favoring high-turnover categories. Advantages include stable cash flows from anchor tenants like cinemas and aquariums, but risks involve negotiation leverage for smaller retailers amid market saturation and slower domestic consumption growth projected at 2-3% for 2025.
Competition and Risks
Key competitors include Lotte World Mall and Times Square in nearby Jamsil and Yeongdeungpo, offering larger above-ground formats with theme parks, alongside emerging projects like Magok One Grove opening in Q1 2025. COEX strengths lie in its unique underground connectivity and event-driven traffic, but weaknesses encompass limited natural light, potential access issues during peak hours, and category overlaps in fashion and dining leading to intra-mall competition. Market factors such as rising operational costs and e-commerce penetration at 25% of retail sales pose risks, recommending diversified tenant mixes to mitigate saturation in Gangnam upscale segment.
