SM Entertainment is one of Korea's 'Big 3' agencies, home to NCT, aespa, Red Velvet, SHINee, and more. In 2021, it consolidated its subsidiaries — previously scattered across Gangnam — into the ACRO Seoul Forest D Tower in Seongsu-dong.
Honest heads-up: the office itself is a working corporate space, not open to visitors. What you can actually visit is 'KWANGYA@SEOUL', the flagship store on B1 of the same building — open to anyone, selling official merch with interactive exhibit zones.
Local tip: weekend and holiday afternoons get crowded; weekday mornings are calmer. Many fans pair the visit with a walk through neighboring Seoul Forest Park. 5-minute walk from Seoul Forest Station (Suin-Bundang Line).
