|“||You broke my windows again! I will not spare you this time!||”|
— Kaminari to Nobita, Gian and Suneo after breaking his window
It is often shown that the baseballs are breaking the glass of Kaminari's window (a woman's window in early manga chapters) or destroying one of his favorite bonsai plants, which angers Kaminari a lot. The children always try not to anger Kaminari and play carefully. He also has a wife who rarely appears and a beautiful niece that the boys fall in love with.
Kaminari is an old man and he wears glasses and wears a Japanese Traditional Cloth most of the time.
He is seen as a hot-headed old man particularly due to children breaking his window frequently, but he is sometimes seen as a good and nice old man towards the girls (as seen in the case of Shizuka in one episode) or when someone apologizes for breaking his glass, seen in the case when Nobita apologizes to him and he happily gives the baseball to Nobita along with other baseballs that he had acquired since then. He is also shown to be protective towards his granddaughter who was a short time love interest of Gian, Suneo and Nobita.
In the birthday episode, Shizuka-chan and the Grandfather Tree, Kaminari is shown to be very passionate of the oldest tree that Nobita, Doraemon and Shizuka tried to save. He'd even rush to city hall to protest to save the Grandfather Tree from being cut down thanks to one of Doraemon's gadgets that encouraged him to do as such. It is because Kaminari used to play next to the Grandfather Tree when he was very young.
In the episode The Great Battle of the Breaking Neighborhood, when Nobita tried to make things right with Kaminari, he offered to bring one of his most prized bonsai to the contest to which Kaminari happily complied. Doing so successfully despite almost every kid in the neighborhood, including Gian mostly, wanting to catch Nobita was enough to make Kaminari forgive Nobita for accidentally breaking his window(s) and bonsai(s).
