One of the reasons that led to Kotoōshū's introduction to sumo wrestling was to help with the household, because his father could not work due to a traffic accident. Kotoōshū sent money to his parents in Bulgaria, but his parents said "I want the child (Kotoōshū) to use it for himself." He has given a washing and drying machine to his mother, a wristwatch to his father, and two cars (a used Ford car and a new Toyota Land Cruiser) to them. In later years Kotoōshū said, "Why do Japanese people ask their parents to send them in after getting started? It's weird."
