Description
Professor is the unnamed homeroom teacher of Nobita Nobi's elementary school class in the anime Doraemon, a recurring supporting character who is referred to simply as Sensei, or teacher, in Japanese and as Mr. S in some English-language adaptations. He is a middle-aged man whose name and age are never established in the original work, though certain anime versions have given him the name Eiichiro Senjou and identified his school as Shitamachi Elementary School. He is typically seen wearing a suit and rectangular glasses, and he has a slightly heavy build, visible nasolabial lines, and a distinctive hairstyle with a straight center parting and shaved sides that gives the impression of a black book resting on his head. In the earliest installments of the series he lived in a small apartment, while later stories show him living in a detached house.
In terms of personality, Professor presents a stern and disciplined front in the classroom. He is frequently shown scolding Nobita for arriving late, forgetting homework, receiving poor test scores, and falling asleep during lessons. His standard punishments include making students stand in the hallway, issuing overwhelming amounts of homework, and ordering them to clean as a form of reflection. He has a common refrain suggesting that students should be studying instead of wasting their time. Beneath this strict exterior, however, he genuinely cares about the wellbeing and growth of his pupils. He comforts Nobita with kind words when the boy is discouraged after receiving a zero, he acknowledges Nobita's effort when Nobita stays up all night to complete a massive assignment even though the work is full of mistakes, and he is openly delighted when Nobita manages to earn a perfect score. He is not infallible, as he can be deceived on occasion, such as when he accepts Suneo's false excuse and unfairly favors him while punishing the other children, and he sometimes fails to notice Gian bullying Nobita even when it happens right in front of him. When he does catch Gian or Suneo misbehaving, he scolds them just as severely as he scolds Nobita.
Professor's motivations are rooted in his sense of duty as an educator. He wants his students to study diligently, behave properly, and develop into responsible people, and he believes that consistent discipline is the way to achieve this. Even when he appears harsh, his goal is to steer children away from laziness and dishonesty and toward effort and integrity. In several episodes he acts as a moral voice, offering lessons about life beyond academics, such as advising Nobita that people should hate the sin rather than the sinner and reminding him that eyes face forward so that people can move ahead in life.
His main role in the story is that of an authority figure and a recurring source of comic tension. The classroom is a regular setting for episodes involving tests, homework, and school routines, and his reprimands often set the stage for Nobita's attempts to solve his problems with Doraemon's gadgets. Professor is also a frequent unwitting victim of Nobita's misuse of those gadgets, and when an invention causes chaos or Nobita's mistakes create trouble, he regularly joins other characters in punishing Nobita. At the same time, he provides emotional support in quieter moments, showing that his place in the series is not limited to scolding.
His key relationships center on his students. His most notable interactions are with Nobita, whom he treats as a problem child with hidden potential; he frequently contacts Nobita's mother, Tamako, to discuss Nobita's academic performance and behavior. He places great trust in the top student Dekisugi, and he treats the other members of the class, including Shizuka, Gian, and Suneo, with the same mixture of authority and concern. Because he is the homeroom teacher, his relationship with the group as a whole forms a constant backdrop for the series' school-based episodes.
Professor's character has developed over the course of the franchise. In the very earliest stories, he was noticeably different, being milder, somewhat timid, overly polite in speech, and even slightly looked down upon by the children, with a different hairstyle and facial expression. As the series progressed, he settled into the strict but caring teacher persona that became his defining portrayal. In the 1979 anime, his famous line ordering students to stand in the hallway became a recurring catchphrase, and later anime eras gradually softened the harsher punishment scenes. An episode depicting Nobita's chaotic entrance ceremony establishes that Professor was present from the very beginning of Nobita's school life, reinforcing his status as a long-term and familiar presence.
Professor has no supernatural abilities and is an ordinary human. His distinctive traits are his authority as a teacher, his sharp tongue, and his talent for assigning punishing homework. More meaningfully, he is capable of inspiring his students through sincere encouragement, and his effectiveness as an educator lies in balancing strictness with genuine warmth and concern for their futures.
