Ittan Gomen is a recurring Yo-kai in Yo-kai Watch, inspired by the Japanese phrase "ittan gomen" (meaning roughly "excuse me for a moment"). He is a comedic character who appears as a nuisance or distraction, often interrupting situations and causing confusion with his apologetic but troublesome nature. In the series, he represents the idea of an annoying interruption, and his presence is used mainly for humor rather than as a major plot-driving figure.
