Kirikaeshi is a drill done with a partner that involves a succession of strikes to e.g. the head (men, in Japanese). Kirikaeshi was established as a basic exercise toward the end of the Meiji era (1868–1912). The exercise typically begins with a strike to the center of the head, followed by a series of alternating strikes to the left and right sides of the head (yokomen). Though the exact method of kirikaeshi can vary among dōjō, the most common scheme involves a single strike to the center of the head, followed by four angled strikes going forward (starting on the receiver's left side), and five strokes going backward. Kirikaeshi practice is the staple of kendo training. It teaches a number of important principles including proper distance and timing, accuracy, rhythm, and smoothness.
