Ukitake is a tall man with a somewhat emaciated appearance, caused by an illness which occasionally causes him to cough up blood. Because of his illness, he often spends his time recuperating at Ugendō, his family’s estate. During one of his attacks when he was much younger, his hair turned white over a three-day period.
