Description
Ginnosuke Nohara is the paternal grandfather of Shinnosuke and Himawari, and the father of Hiroshi Nohara. He is sixty-five years old and lives with his wife, Tsuru, in the rural prefecture of Akita, where the family home is a traditional Japanese house located in the countryside.

In terms of personality, Ginnosuke shares a great deal in common with his young grandson. He possesses a mischievous and playful nature, enjoys playing strange and elaborate jokes, and has a very noticeable interest in pretty young women, a trait he has passed down to both his son and grandson. He is affectionately called Gin-chan by his family. His behavior is often a source of exasperation for his daughter-in-law, Misae, as he tends to overstay his welcome and engage in immature antics.

Ginnosuke plays a recurring role in the story as a visiting family member who brings rural charm and chaos to the Nohara household in Kasukabe. He lives on a farm in Akita with his wife, and the Nohara family occasionally travels to visit him. A running gag associated with him is his method of arrival; he will call or send a letter announcing his intention to visit, only to appear suddenly without warning, much to the family's shock. When the family visits him in Akita, he often greets them in strange and embarrassing ways, such as by dressing up as various movie characters.

His key relationships are defined by both affection and rivalry. He has a very strong bond with his grandson, Shinnosuke, with whom he likes to do weird things. It is implied that he taught Shinnosuke many of his unusual habits. He shares knowledge of country life with his grandchildren, instructing them on activities like catching bugs and fishing, and growing vegetables. Conversely, his relationship with Misae is strained, as she dislikes his long, unannounced visits and his disruptive influence. He also has a notably bad relationship with his daughter-in-law's father, Yoshiji Koyama, with whom he shares a mutual rivalry.

Throughout the series, Ginnosuke does not experience significant personal development; instead, he serves as a consistent comedic force whose primary motivation is to enjoy life, tease his family, and spend time with his grandchildren. His notable abilities include his skill at farming and traditional country activities, which he proudly demonstrates. Furthermore, his tendency to behave like a much younger man, combined with his sudden materializations and elaborate pranks, are his defining character traits.
