Similar to the original London staging, the set of the 1,200-capacity CATS Theatre is built on a revolving stage floor such that during the overture, the stage and sections of the stalls revolve approximately 180 degrees into place. In 1998, the Japanese production underwent major revisions to the choreography, staging and costume designs. Following further revisions in 2018, the current incarnation features 27 named cats, including both Jemima and Sillabub (who have evolved into two separate characters), and an original character named Gilbert.
