Ukitake is a tall man who suffers from tuberculosis. This causes him to frequently have a sickly appearance and is what causes his pale complexion and white hair.
110 years ago he wore his hair in a long ponytail. Currently, his hair is worn long, cascading down his back almost reaching his waist. He wears it parted on the left side with one long piece that tends to fall over his right eye. His eyes are a hazel/brown color. Ukitake wears the common Shinigami uniform with a long sleeved captain's haori, with a red lining. He wears a narrow obi in which he secures his Zanpakutō.
At first, his lieutenant Kaien Shiba performed them, but following his death they were performed by his 3rd Seat officers, Kiyone Kotetsu and Sentarō Kotsubaki. He often spends his time recuperating at Ugendō, his family's estate.
