Aragoto (荒事), or rough style, is a style of kabuki acting that uses exaggerated, dynamic kata (forms or movements) and speech. Often, aragoto actors wear bold red or blue makeup (kumadori), and have costumes that are padded and enlarged. The term aragoto is an abbreviation of the term aramushagoto, which literally means reckless warrior matter.
