Movie
Description
Jam-ojisan is the narrative's chief baker and inventor. He accidentally birthed Anpanman when a shooting star struck his oven during anpan preparation, infusing life into the bread-headed hero. This pivotal moment cemented his role as Anpanman’s creator and guardian, instilling in him the principle to always strive his utmost. His mechanical ingenuity shines through inventions like the Anpanman Mobile and repairs of mechanical beings, while his vast knowledge—gathered from youthful travels—fills the library in his home.

Physically, Jam-ojisan mirrors Anpanman with age-distinct traits: gray hair, fluffy eyebrows, a mustache, and faint red cheek and nose tints. He consistently wears a white chef’s hat, shirt, pants, and apron, paired with blueish-gray shoes. His profound kindness and nurturing demeanor prioritize others' well-being, echoing Anpanman’s altruism. This compassion drives him to craft replacement heads for Anpanman whenever the hero sacrifices his own to feed the hungry or sustains damage.

Jam-ojisan nurtures key bonds throughout the story. He holds deep paternal love for Anpanman, whom he created and raised. With Batako, he shares a non-biological familial closeness, cohabiting and showing mutual care—their connection possibly tracing to her infancy. He supports Melonpanna as a father figure and fosters Creampanda’s talents as an adoptive child. Despite Rollpanna’s instability from her dual hearts, he persistently invites her into the bakery fold, retaining affection for his creation. He aids fellow bread heroes like Shokupanman and Currypanman; early media implied he made Currypanman, though this origin later blurred. Cheese, his dog, accompanies him, though their bond is less intense than with Batako.

Further facets include motorcycle proficiency and possible undisclosed inventor-researcher skills. In Anpanman’s world—devoid of humans—he and Batako are fairies. Early 1973 picture books called him "uncle" or "old man" before settling on Jam-ojisan. An abandoned manga detail depicted him smoking a pipe, omitted in later adaptations. He is alternatively known as "Mr. Jam" in English contexts.
