Nexon Computer Museum

This guide to the Nexon Computer Museum on Jeju follows Kim Jung-ju, the reclusive Nexon founder who quietly built a private hoard of vintage computers and arcade cabinets even as he faced a bribery investigation that dominated Seoul headlines through the 2010s. You'll hear how a college friendship, a stock windfall and a years-long prosecution unfolded alongside a hobby collection that began around 2003 and eventually filled four floors on this side of the island. Along the way it lingers on individual pieces, including a working first-generation Apple bought at Sotheby's.
