"I kicka your ass!" —Junichiro, "Returning Japanese"
Junichiro (born c. 1946) is Cotton Hill's illegitimate son who was conceived at the end of World War II, and the half-brother of Hank Hill. He is an assistant manager of a robotics company.
His mother is 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 and his feet surgically attached to his knees. Junichiro would not meet Hank, Cotton, or the rest of the Hill family he was around 56 years old in the 2 part special "Returning Japanese".
Biography[]
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 of which he is even more ashamed of this than Hank, saying he has never had the courage to propose marriage to a woman due to fear he could not have a child with her. 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 and is responsible for more employees than Hank. Junichiro is also fully fluent in English as well as Japanese. He and Hank have similar interests into sports.
When Junichiro first met Cotton, he said he was ashamed of who his birth father was and wished he had never been born. This made Cotton angry and he made a journey around Japan in order to spit in the emperor's face. When Hank tells him, Junichiro reacts with horror at this, for if this occurs it will ruin his business and personal reputation beyond measure. Junichiro and Hank teamed up to stop Cotton, and during this time the two brothers bonded and learned they had much in common. Both even taught the other some of their other culture to better help. When they caught up to Cotton, Junichiro apologized to Cotton for what he had said and declared Cotton as his father and 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 while getting Junichiro's name correct.
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 Kleinschmidt's wedding.
He later makes a brief appearance in "No Hank Left Behind" over a video call. This was the first time he was seen with his youngest half-brother G.H. Hill.
Relationships[]
- Michiko: Similar to Hank towards Tilly, Junichiro appears close to and protective of his mother. They are not shown together much but it appears clear that he cares for her very much.
- Wataru: Junichiro's step-father that Junichiro claims to be his true father. It was stated in "Returning Japanese" that Wataru was not bothered by Junichiro having been born out of wedlock from another man and raised the young boy as his own. Because of this, Junichiro saw him as his real father instead of Cotton.
- Hank Hill: Junichiro's younger half-brother. At first, Junichiro was distant from Hank when they first met as he felt that Hank had the upbringing he should have had but didn't. He soon began to change his behavior toward Hank when they started bonding and Hank helped to prevent shame falling onto Junichiro's family when Cotton attempted to spit on the emperor. During that time, Junichiro came to accept Hank as his brother and the two are assumed to have kept in touch after parting ways. This is later confirmed by Junichiro taking part in the family meeting in Season 14.
- Cotton Hill: Junichiro's biological and estranged father. Junichiro appeared to be aware of Cotton prior to their first meeting and showed great displeasure of Cotton's actions during and after meeting Michiko. During the dinner after they met, Junichiro announced that he could not overlook Cotton's actions and did not accept their relation. It was only through Hank's actions and efforts that Junichiro would come to accept Cotton as his birth father.
- G.H. Hill:Junichiro's youngest half-brother. There has not been any direct interaction between them, but he is aware of GH. In Season 14, they are seen together for the first time and Junichiro called both him and Hank his brothers.
