Taishu engeki ("theatre of/for the masses") is a genre of popular theater in Japan. Frequently described as "light theater" or some people call it working-class Kabuki.

Though different interpretations and definitions abound, the chief distinguishing feature of taishu engeki is the notion that it is intended as entertainment for regular people. Taishu engeki has 3 basic structure; they start with music dance/ (a certain kind of samurai moves) and then main story play and end with musical dance and singing. Audience can shout, clap and give money or gifts while the actor is performing.

Taishu engeki troupes tend not to be connected with a single theater, but travel, performing at small local theaters, community centers and the like. Ticket prices are relatively low compared with the major forms of urban theater, such as kabuki, opera, and Broadway musicals, and efforts are made to inspire a feeling of closeness between the audience and the performers.
