Located at 65-1 Suha-dong, Jung-gu, Seoul, it sits at the core of daily routes for both tourists and office workers, covering Myeong-dong Walking Street, Lotte Department Store, Namdaemun Market, and surrounding office buildings. With no detours, no obstructions, and 100% guaranteed foot traffic visibility, it is adjacent to Exit 3 of Euljiro Entrance Station on Subway Line 2. This is a prime visual spot at the intersection of the Myeong-dong commercial district and the Euljiro financial/commercial belt, making it a high-exposure medium that every visitor to Korea and local core consumer group will inevitably pass by.
Large screens in Seoul's core commercial areas are limited in supply but high in demand. The Changjiang Building location is a scarce core resource in the Myeong-dong–Euljiro area, with converging subway, bus, and car traffic. The daily pedestrian flow exceeds 600,000 and vehicle flow exceeds 150,000, doubling during holidays and peak tourist seasons. The annual exposure exceeds 200 million people, making it one of Korea's top-tier high-traffic media. Its landmark status naturally attracts check-in sharing on social media, easily triggering spontaneous online sharing, achieving a dual effect of "offline exposure and online diffusion."
Over 90% of travelers pause in front of the screen and then directly enter surrounding commercial establishments, realizing seamless conversion from "brand impression → emotional stimulation → on-site consumption." There are no similar large media distractions nearby; the single screen occupies the core vision alone. Brand information reading rate and retention far exceed ordinary street screens, achieving long-term brand asset accumulation with "one placement, full-area penetration," forming a closed loop of "offline visual impact → online viral spread."
The value of a large screen lies not in being 'the biggest' but in being 'the most accurate'—precisely positioning the first impression for international tourists exiting the station and the emotional explosion point of fan economy. It is a rare medium for high-end brands to achieve 'awareness → emotion → conversion' integrated communication. With the core advantages of monopolizing traffic in two commercial districts, strong visual impact, high-conversion audience, and all-day exposure, it is a top-tier outdoor media for brands to capture Korea's core commercial areas and reach global tourists and local high-net-worth individuals.
This screen is a popular choice for the return of Korean idols and birthday support campaigns, frequently appearing in materials shared within fan communities, indirectly driving secondary dissemination of brand content. Its surrounding bus routes are dense, convenient for clients to monitor and shoot materials on-site. Compared to small lightboxes and indoor screens in the Myeongdong commercial area, the unit exposure cost is lower. Long-duration display and high-frequency rotation effectively enhance brand recall.
Large screens in Seoul's core commercial areas are limited in supply and subject to strict approval. The Changjiang Building location is the only vertical landmark large screen in the Myeongdong - Euljiro area. Its resources are irreplaceable and retain long-term value. As a landmark outdoor media asset scarce in core commercial areas, its core advantages are high-end audience, flexible operation, policy incentives, and asset appreciation, making it an excellent target for entering Korea's outdoor advertisingmarket.
The large screen enjoys a 360° unobstructed view. Whether for passing traffic or stationary pedestrians, the image can be clearly captured, with effective viewing time far exceeding other outdoor media in the same area. Advertising exposure has extremely high conversion value and also provides a solid traffic foundation for investment returns.
