The Japanese verbal noun 'コーチ (こうち)' is borrowed from the English word 'coach'. It refers to a person who trains or instructs individuals or teams, particularly in sports, but it can also be used in other contexts such as life coaching or professional development. For example: He is a soccer coach「彼はサッカーのコーチです」(かれはサッカーのコーチです). She hired a coach to improve her public speaking skills「彼女はスピーチのスキルを向上させるためにコーチを雇いました」(かのじょはスピーチのスキルをこうじょうさせるためにコーチをやといました). The term is widely understood in Japanese and retains its original English meaning.
