"I kicka your ass!"
~Junichiro, Returning Japanese

Junichiro Hill was conceived at the end of World War II. His mother was a Japanese woman named Michiko who served as Cotton's nurse, draining the fluid from his legs after his shins had been blown off by machine-gun fire from Japanese soldiers. Cotton and the rest of the Hill family did not meet Junichiro until he was in his early 50s.

Junichiro looks, acts, and talks like a Japanese version of Hank and shares many of his tendencies, such as shouting "Bwahh!" when startled; rubbing the back of his neck when he's nervous; and also having a narrow urethra (because of this, he is unmarried). Junichiro works at a factory that makes robots and robot accessories, and he is passionate about his work because they are clean and efficient, very similar to how Hank views propane and propane accessories. Junichiro is an assistant manager at his company, much like Hank's job as assistant manager of Strickland Propane - the only difference being that Junichiro is one of thirty assistant managers.

When Junichiro first met Cotton, he said he was ashamed of who his father was and wished he'd never been born. This made Cotton angry and he made a journey around Japan in order to spit in the Emperor's face. Junichiro and Hank teamed up to stop Cotton, and during this time the two brothers bonded and learned they had much in common. When they caught up to Cotton, Junichiro apologized to Cotton for what he had said and declared himself to be a Hill. Touched by Junichiro's apology, Cotton in turn dropped his plan to spit on the Emperor. Instead he told the Emperor that he forgave the Japanese for taking his shins ("No hard feelings, Tojo") and proudly introduced both of his sons to the Emperor.

Junichiro did not appear in the series again until "Lucky's Wedding Suit," in which he is seen among the many guests at Luanne's and Lucky's wedding. That was also the last time Junichiro appeared in the series.


  • Junichiro (純一郎, Junichirō) is a male given name meaning "Genuine First Son".
  • Junichiro's job is similar to Hank's job, as they both sell a product and product accessories and are both assistant managers. (Propane & propane accessories, Hank. Robot and robot accessories, Junichiro.)
