Kirikaeshi
Kirikaeshi(切り返し:きりかえし), not to be confused with the backwards throw used in sumo and jujutsu with the same name, and with a literal meaning of "cutting repeatedly", is a kendo exercise, combining the practice of attacking and receiving strikes and is meant to develop physical strength, spirit, and vigor. Kirikaeshi is also known as uchikaeshi(打ち返し:うちかえし) "striking repeatedly".
