The official website for the stage play adaptation of Kei Urana’s Gachiakuta manga announced on Wednesday that it canceled the Wednesday and Thursday performances, after lead actor Hikaru Imamaki, who portrays Rudo, injured his leg during the play’s Tuesday evening performance.
Imamaki’s injury was immediately examined and he was diagnosed with a torn meniscus (a common knee injury, mostly seen among athletes, caused by sudden twisting movements while the foot is planted and knee is bent). After discussions with the parties involved including Imamaki, his agency, and the production committee, it has been decided that Imamaki will withdraw from the remaining performances of the Gachiakuta stage play from May 29 onward, to focus on his treatment.
Accordingly, the stage play’s staff announced that actor Ryota Kamiya will replace Imamaki to play the role of Rudo, and performances will resume on Friday from the afternoon performance.
The stage play is scheduled to run at that Stellar Ball in Tokyo from May 22-31, and it will run at the Rohm Theater in Kyoto from June 5-7.
