Sugar Mountain (シュガー・マウンテン, Shugā Maunten) is the title of a tertiary character featured in the seventh part of the JoJo's Bizarre Adventure series, Steel Ball Run, introduced in the The Promised Land: Sugar Mountain story arc. An old woman with the appearance of a young girl, she is trapped by and made the current guardian to a Great Tree possessing a Stand of the same name.
Sugar Mountain has the appearance of a young girl, with dark hair in a hime cut and straight, eyebrow-level bangs. She wears a bonnet, a necklace in the shape of a cluster of grapes, a short dark dress with a light one underneath, leopard-patterned sleeves, and long socks with a pair of leather boots.
Behaving much like a young child with a vivid imagination, Sugar Mountain does not seem to have aged physically or mentally during the roughly fifty years she spent bound to the Tree. She passes her time playing make-believe with dolls made from cloth and twigs, and has drawn rooms for an entire 'house' within the tree-hollow she lives in. Johnny deduces that she is nearly blind, noticing the mark of a cane around her abode. In spite of her childish mannerisms, she highly values honesty, and is able to comport herself with some maturity when she explains the Tree and the nature of its Stand to Johnny and Gyro, making sure that they understand that they must use up all of the items given by the spring by sunset. She expresses a strong desire to free her parents and leave the forest with them together, and holds Johnny and Gyro in high regard for their ability to escape the Tree's ability.
At one point in the past, Sugar Mountain and her parents encountered the great tree. Her father had dropped an axe and managed to acquire it back from the guardian, plus a golden axe for being honest. However, Sugar Mountain's family failed in using it up before sunset and they were turned into tree fruits, slumbering for so many years Sugar Mountain lost count of the time. It is estimated that she was prisoner of the tree for about 50 years. At one point, it is Sugar Mountain's turn to be the guardian of the tree.
She encounters Gyro and Johnny while they search for the ears and right Arm of the Saint's Corpse after she steals one of Gyro's Steel Balls. After a brief introduction, Gyro attempts to search for it in her Tree. She asks the pair a series of questions, offering in an exchange not only Gyro's Ball, but money, a piece of gold ore and a few gemstones.
A sort of game emerges to Gyro's understanding. When he severs the ears of the rabbit Johnny caught earlier and drops it into the spring by the Tree, Sugar Mountain produces the Ears of the Corpse, to her surprise. At some point before departing her, Gyro also drops the rabbit's (right) arm, retrieving the Corpse's Right Arm.
As per the rules of the Tree's Stand, Sugar Mountain; Johnny and Gyro are obligated to use or spend everything they gained in their exchange with her before sunset, under threat of the both of them joining the the Tree's collection of inanimate human "fruits".
When they succeed, Sugar Mountain, along with her parents, are released from the Tree.
- Throughout the ages, each watcher over the Stand of the large tree is named Sugar Mountain, making it more of a title than an actual name.
