Nobisuke Nobi is the father of Nobita Nobi and the husband of Tamako Nobi. He works as an ordinary salaryman, commuting to an office job each day. His childhood took place during World War II, and he grew up in a time of hardship. He has a younger brother named Nobiro Nobi.

In terms of personality, Nobisuke is gentle, easygoing, and patient. He often arrives home from work to find Tamako scolding Nobita, and he tends to soften her anger with calm words. He shares many of his son’s traits, including a laid-back attitude, clumsiness, and a tendency to be forgetful. He is not particularly ambitious in his career, having accepted a modest, stable life. Despite this, he possesses a quiet wisdom and offers Nobita encouragement rather than harsh discipline. He is also somewhat ineffectual at times, occasionally avoiding household conflicts by quietly disappearing. His hobbies include painting, which was once a serious dream of his; as a young man, he was a highly skilled painter and even won awards. He gave up the opportunity to study painting abroad and marry a wealthy businessman’s daughter because he wanted to carve his own path in life. That decision led him to meet and marry Tamako. He still paints occasionally. Other pastimes include fishing (though he is not very skilled), golf, watching baseball and golf on television, and listening to music on expensive audio equipment. He has bad habits: he smokes heavily and has tried to quit many times without success, he enjoys drinking alcohol and sometimes becomes drunk at social gatherings, and he has taken the driver’s license test many times but never passed. He is also prone to nagging and has a poor memory.

Nobisuke’s primary motivation is the well-being of his family. He wants to provide for them and be a positive presence in Nobita’s life. He believes in gentle guidance rather than strict rules. He is not driven by material success or status; instead, he values stability, family bonds, and simple pleasures.

His role in the story is that of a supporting character who provides emotional balance in the Nobi household. While Tamako represents discipline and worry, Nobisuke represents patience and reassurance. He often mediates conflicts and helps Nobita feel understood. He serves as a relatable example of an ordinary, caring father.

His key relationships are with his wife Tamako, his son Nobita, and the robot cat Doraemon. With Tamako, he has a complementary partnership: she is strict and practical, while he is calm and lenient. They love each other and work together to raise Nobita. With Nobita, Nobisuke is nurturing and believes in his son’s inherent goodness despite his poor grades and frequent failures. He occasionally shares stories from his own childhood to teach lessons. He fully accepts Doraemon as a member of the family, treating him with the same affection he shows Nobita.

Character development is subtle but present. Through flashbacks and special episodes, viewers learn about Nobisuke’s lost dream of becoming a painter, his wartime childhood, and his acceptance of an ordinary life. These moments add depth and show that he understands Nobita’s struggles because he once faced similar ones himself. He remains a steady, unchanging presence, but his backstory enriches his character.

As for notable abilities, Nobisuke is a talented painter, though he no longer pursues it professionally. He is also a reasonably competent worker at his office, though not outstanding. He lacks skill in driving, fishing, and golf, and his attempts to quit smoking are a running joke. He has no superhuman or gadget-based abilities; his strengths lie in his emotional intelligence, patience, and unconditional love for his family.
