Yamamoto is the oldest captain in the Gotei 13. He has the appearance of an old man with red eyes a very long white beard, and long eyebrows.There are many scars on his torso and head, the two most prominent being a pair of long, perpendicular scars above his right eye, suggesting numerous battles in his past. After his brief confrontation with Aizen, Yamamoto lost his left arm. He wears the standard Shinigami uniform, but its size is greatly exaggerated. He also drapes his haori over his back instead of actually wearing it. Despite his old and frail appearance, he has a very muscular body that he only reveals when he takes a certain battle stance, something that, Shunsui claims, is not seen too often.
As the captain-commander of Gotei 13, Yamamoto is highly respected by most of the Shinigami, most notably Sajin Komamura, who views Yamamoto as a benefactor who saved his life. The embodiment of conviction, Yamamoto follows the laws and regulations of Soul Society to the letter, and expects the same of others. He is not a man to tolerate insubordination, and is vocal with those who attempt to act in such a manner. He is quick to anger in the face of possible betrayal, and can be quite aggressive in combat. When in a state of peace, he carries himself with an air of frailty, even to the point where he has fallen asleep standing while awaiting Shunsui Kyōraku's arrival for a meeting. Due to years of experience, Yamamoto very rarely shows any sign of distress or surprise, usually responding by opening one or two of his eyes, which are partially closed slits the majority of the time.
Yamamoto is very loyal to Soul Society and takes his duties very seriously, expecting the same from the rest of the Gotei 13. His loyalty is so great that he is willing to sacrifice himself and the Gotei 13 in order to defeat Aizen, believing it to be their duty to lay down their lives for the sake of the Soul Society if necessary. Another example where Yamamoto shows his loyalty, is when he become visibly angry when Shunsui, Byakuya and Kenpachi lose their haoris and show little regret; to him the haori represents their status as captains.
Yamamoto founded the Shinigami Academy about 2100 years before the current time. Yamamoto was himself a teacher at this academy, and personally instructed Shunsui Kyōraku and Jūshirō Ukitake. He admits to being rather proud of the two. When they became captains, he boasted about them as though they were his own sons. Approximately one thousand years ago, Yamamoto founded and became the Captain-Commander of the Gotei 13.

Ryūjin Jakka (aka Flowing Blade-like Flame"): His Zanpakutō is the oldest and the most powerful fire-type Zanpakutō and has greater attack power than all other Zanpakutō in Soul Society. In its sealed form, Ryūjin Jakka usually takes the appearance of a harmless wooden staff which can be used like a spear. At any time, Yamamoto can instantly remove that disguise, by peeling off the wood, to reveal its true form of a standard katana with a dark purple handle and a circular hand guard. Its power is so great that even the strongest of Shinigami are afraid of it even in its sealed form.
- Shikai: Its Shikai command is "Reduce All Creation to Ash": The release of his Zanpakutō comes with an extreme release of spiritual pressure affecting all in the area, and can be felt for miles upon miles across all of Seireitei.
