Jason Ozuma (ジェイソン・尾妻 lit. jeison ozuma) is a non-recurring character in Hajime no Ippo.
Jason is a retired boxer who was affiliated with the Hachinohe boxing gym. He was known for his immensely powerful right hooks, intimidating appearance, but surprisingly kind and compassionate personality.
Jason is an African-American soldier stationed at the Misawa Air Base near Hachinohe, Aomori. As trained military personnel, he boasts an impressive body structure and is first seen in the weigh-in room with his coach. Ippo, who arrived shortly after, comments on Ozuma's intimidating height and appearance.
Later seen in the Rookie King Tournament match against Ippo, Ozuma proves to be a difficult and equally durable opponent. Unrelenting and fearsome, he is revealed to have an explosive hook equal to, if not more powerful than, Takamura Mamoru's. However, Ippo's fighting spirit and resolve eventually unnerved Ozuma, who believed that Ippo could not be hurt. After failing to land a finishing hook, Ippo retaliates with a damaging counterattack, causing Ozuma to lose his first match. Shortly after, it is revealed by Okita Keigo that Ozuma has retired due to spine damage from his match against Ippo.

AppearanceTowering in height compared to Ippo, Ozuma's appearance can prove to be incredibly intimidating. He has a dark skin tone and black hair. His hairstyle, as expected of a man from the military, is cut short and styled neatly to prevent any stray strands to fall in his line of vision. In addition to that, Ozuma also has a neatly trimmed stubble beard that wraps around his chin and mouth. His eyebrows are short and moderately thick. Ozuma's eyes are onyx in color.
Despite his fearsome height and overall appearance, Ozuma possesses a polite and outgoing personality. He is kind, compassionate, and charitable, stating that his reason for boxing is to earn money for his gym. He treats his coach and gym mates like his own family, supporting them and fighting for them with hardened resolve.
Ozuma is an in fighter, most frequently fighting at close range to increase the precision of his immensely powerful hooks. His body, built expertly for an in fighter, has the ability to withstand the punches of the (then still inexperienced, but still powerful) esteemed hard-puncher Ippo.
When he throws his signature hook, his body opens up, leaving him very vulnerable to body blows and counterattacks.
- He is the first African-American character to appear in the series, as well as Ippo's first foreign opponent.
- Based on the Japanese Wiki, Jason's fighting style was modeled after Yoshino Hiroyuki.
