Background
When Cartman, Stan, and Kyle build a massive ladder to Heaven so they can get tickets to Lolly's Candy Factory from Kenny, the Japanese claim to have already reached Heaven with their own ladder. Nobunaga reports on the weather in "Heaven", which is very obviously a studio in Japan. Despite this, the boys parents still believe they actually reached Heaven.

Nobunaga has combed black hair that appears to be graying, thin black eyebrows, and a small black mustache. He wears a dark blue suit, a white undershirt, a red tie, black pants, and black shoes. He has the typical features of Asian characters as depicted on the show, including squinted eyes and an exaggerated Japanese accent.
