Jaha Koo is a South Korean theatre/performance maker and music composer.

The first part of the trilogy, Lolling and Rolling, was first presented by the Zürcher Theater Spektakel in 2015. The second piece, Cuckoo, was premiered at the Steirischer Herbst Festival in 2017. Koo’s current project is the final part of the trilogy, The History of Korean Western Theatre. It will premiere in the spring of 2019. Koo majored in theatre studies (BFA) at Korea National University of Arts and studied at DasArts (MA) in Amsterdam. GuJAHA is the pseudonym Jaha Koo uses as a music composer.
