Uramichi Omota is a 31-year-old man employed as a gymnastics instructor for "Together with Mama," an educational program for children. Before his young viewers, he must project a cheerful and energetic persona. Away from work, and occasionally even on camera, he inevitably reverts to his true self, which stands in stark contrast to his television image. In reality, he is miserable and thoroughly fed up with his current way of life. Uramichi Oniisan is a dark comedy that exposes the less-than-glorious reality of adulthood through its characters, who serve as unfortunate examples.
