Sanada Kazuki (真田 一機) is a recurring character in Hajime no Ippo. He was the antagonist of the television special Champion Road.

His surname is Sanada. In Japan, surnames come before given names.

History Edit

Sanada was the Junior Featherweight Champion before relinquishing the title to conquer another class. He is a boxer who relies on science to win his fights. In his title fight against Ippo he used science to calculate how many seconds he will be immobilized (even though Ippo's fighting spirit kept him going and proved his theory wrong). He can reduce his pulse rate between rounds which helps him to fight at his full potential again.

He is known to be very close to Ippo as he didn't hesitate to help him when Ippo thought that Takamura had a detached retina.

Fighting Style and TechniquesEdit


Sanada in the ring.

Being a former Japanese champion Sanada was a highly skilled boxer. His fighting style focuses on skill and strategy rather than overwhelming strength or speed. Sanada's boxing involves his knowledge of the human body to drive in major attacks at pinpoint precision to stop and breakdown his opponent from the inside rather than attacks to the body that do major external damage. His techniques allow him to drive in major attacks with even the slightest opening in an opponent guard. His understanding of anatomy also allows him to target the 4 vital organs of the body, which would lead to cyanosis.



Sanada himself has no outstanding weaknesses. He lost to Ippo because he was too focused on his strategy of lowering Ippo's stamina. This might be more of a fault of Hama Dankichi than Sanada, since it was Dankichi who instructed Sanada to focus on that strategy. Considering his intelligence, it is possible Sanada would have developed Sawamura's strategy had he focused on countering the Dempsey Roll instead.



  • The video game system Sanada was playing on with Kinoshita's daughter bears a striking resemblance to the original Xbox, though the controller is a cross between the Xbox's and PlayStation's. The two game cases sitting next to the console read "Megamix 200X" and "Buyo". The fighting game they were playing feature two male characters with similar appearances to that of characters from the [Seint Saiya] anime.
