What does hansoku-chui mean in Japanese?

Hansoku-chui (反則注意) in Japanese refers to a warning issued in Martial Arts or sports for a foul or infraction. It serves as a formal notice to the athlete that their behavior is against the rules, but it is not as severe as a disqualification. Repeated violations following a hansoku-chui can lead to more serious penalties. The term reflects a disciplinary measure aimed at maintaining fair play.
