Komamura is an anthropomorphic wolf, although he is often mistaken for a dog. Initially, he was very self-conscious about his appearance, so he wore gloves with bracers, as well as a helmet, to conceal his entire body. However, he later gains enough confidence to go on without his helmet after Kaname Tōsen's betrayal against Soul Society, along with former Captains Sōsuke Aizen and Gin Ichimaru. He is the tallest captain of the Gotei 13. His fur is light-brown in color, which is the same color as his gloves. He also wears shoulder weights over his haori and large, plated boots instead of sandals.
In contrast to his imposing physical stature, Komamura has a heart of gold, as well as being a loyal and grateful subordinate to Captain-Commander Genryūsai Shigekuni Yamamoto, to whom he owes great gratitude for taking him in; so grateful that he would even die for him. The betrayal and subsequent departure of his close friend, Kaname Tōsen, may have adversely affected his self-confidence and view of himself, since Tōsen was the first person to have accepted him for who he is and not what he is.
