COEX Convention and Exhibition Center
Major exhibition and event complex in Samseong-dong, Gangnam, with halls, conventions and a connected mall. The event you came for determines its actual entry time, ticket price and hall; there is no single schedule for all of COEX.
Checked October 9, 2026: COEX lists the free Korea–Japan Festival for Saturday October 10, 11:00–18:30 in Hall D, 3F. Other exhibitions have separate schedules and ticket policies. Check the exact hall, venue map and organizer notice before arriving.
Why go
Use COEX as a dependable transit and venue anchor for indoor Seoul events. An official October 10 Korea–Japan cultural festival is in Hall D on the third floor; this is not the general mall entrance or a complex-wide event.
