Kiyoshi has brown hair and dark eyes. In a flashback, he wears a black captain hat and a black captain uniform but a photograph shows that he is seen wearing a white captain uniform.
He was supposedly in the navy during World War II. During the film, Seita and his sister attempt to write to him several times but never receive a reply. Much later at the bank, Seita overhears that the Japanese has lost the war and the entire fleet of ships has been sunk. Astonished, Seita finally realizes why his father hasn't written back.
