Ine Yamada is a central character from the 1980s anime series Ojamanga Yamada-kun, depicted as the housewife of the Yamada family. In addition to her domestic role, she serves as the landlady of the Yamada-so apartment building, which the family runs as a source of income.

Her personality is largely defined by her daily experiences and concerns as a mother and wife in a busy household. In one notable storyline, she becomes preoccupied with her physical appearance after noticing she has recently gained weight. This concern reveals a relatable, self-aware side to her character, as she takes proactive steps to address her worries. Her motivation in this instance is clear and practical: to lose weight and feel better about herself.

This goal leads her to join a nearby tennis club, highlighting her willingness to take action to solve personal problems. Her role in the story often involves interacting with her family members, particularly her son, Noboru. The narrative takes a comedic turn when she goes to the tennis club and unexpectedly encounters him there, as he is trying to join the same club for his own reasons, specifically to meet girls. This incident showcases how her personal journey can intersect with and drive the humorous, family-centric plots of the series, setting up situations that reveal the dynamics between her and her children.
