An old man who lives next to the vacant lot where Nobita and the gang play baseball. They sometimes "accidentally" throw baseballs, rocks, or even one of Doraemon's gadgets through his window, breaking it and knocking over his prized bonsai. The children refer to him as Kaminari-oyaji (雷おやじ,, Old Man Thunder?), because he shouts so loud that they scatter. Kaminari is his family name.
