At which Seoul landmark does Rumi sing the finale of KPop Demon Hunters?

Rumi sings the finale of KPop Demon Hunters at Namsan Tower.

The landmark, officially known as N Seoul Tower, is one of Seoul’s most recognizable locations. In the film, it becomes the setting for the final confrontation and for Rumi’s performance of “What It Sounds Like.”

Rumi arrives at the tower and breaks Mira and Zoey out of their trance. The reunited Huntrix then confronts Gwi-Ma and the Saja Boys, making the location both a dramatic battle site and the stage for the film’s emotional resolution.

Namsan Tower is not the city itself; Seoul is the film’s main real-world setting. The tower is a specific landmark within that setting, which is why it is the more precise answer to this question.
