Kaminari

Kaminari (神成さん) is a recurring character in Doraemon.He's an old man living next to the Open Lot where Nobita and his friends play.

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 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.
