Waki is a term used in traditional Japanese theater, particularly in Noh and Kyōgen. It refers to a secondary character, often a companion or a foil to the main character, known as the shite. The waki typically provides context and helps to advance the plot, often representing a more relatable or human perspective. In Noh performances, the waki usually plays a role that is more grounded and realistic compared to the often supernatural or heroic shite. This contrast enhances the storytelling, allowing the audience to engage with the themes and emotions presented in the performance.
