Hajime no Ippo follows Ippo Makunouchi, a shy high school student who helps his mother at home and gets picked on at school. After a passing boxer, Mamoru Takamura, steps in during one of those beatings and takes him to the Kamogawa Gym, Ippo decides to turn professional. The cast is organised around boxing gyms. The Kamogawa Gym is Ippo's home: coach Genji Kamogawa, his senior gym mates Takamura, Aoki and Kimura, manager Yagi and, later, the younger Itagaki. Rivals come from other gyms across Japan, such as Miyata, Sendo of the Naniwa Gym in Osaka, Mashiba of the Toho Gym and the veteran Eiji Date. This page covers 16 characters with their gym, weight class, fighting style and Japanese voice actor, written without fight results.
Protagonist
Ippo Makunouchi 幕之内 一歩
Kamogawa Gym · Japanese voice: Kōhei Kiyasu
The protagonist. Timid and polite outside the ring, Ippo becomes stubborn and fearless once the bell rings. He fights at featherweight as an in-fighter, closing distance behind a tight peek-a-boo guard and throwing heavy body shots and hooks. He trains at the Kamogawa Gym under Coach Kamogawa and wants to learn what it means to be strong. Voiced by Kōhei Kiyasu.
Main characters
Mamoru Takamura 鷹村 守
Kamogawa Gym · Japanese voice: Rikiya Koyama
The boxer who rescues Ippo from bullies and brings him to the gym. Loud, vain and fond of teasing, Takamura is also the gym's most gifted fighter and its unofficial leader, and he acts like a rough older brother to Ippo. He fights at middleweight and has a powerful left jab. Voiced by Rikiya Koyama.
Masaru Aoki 青木 勝
Kamogawa Gym · Japanese voice: Wataru Takagi
A lightweight at the Kamogawa Gym and one of Ippo's seniors. A former high school delinquent, he is the comic relief of the group, always scheming with Kimura and Takamura. In the ring he uses odd, unpredictable tricks such as the 'Frog Punch' to throw opponents off balance. Voiced by Wataru Takagi.
Tatsuya Kimura 木村 達也
Kamogawa Gym · Japanese voice: Keiji Fujiwara
Aoki's best friend and another of Ippo's seniors at the Kamogawa Gym. Calmer and more stylish than Aoki, he relies on a quick left and good footwork as a junior lightweight. He has a romantic streak and often jokes around with the group, but takes his own career seriously. Voiced by Keiji Fujiwara.
Rivals
Ichiro Miyata 宮田 一郎
Kamogawa Gym (later Kawahara Gym) · Japanese voice: Tomokazu Seki
The young prodigy Ippo spars with on his first visit to the gym, and the rival Ippo most wants to face. Cool and reserved, Miyata is an out-boxer and counter-puncher who learned his style from his father, a former boxer. He fights at featherweight even though his frame suits a heavier class. Voiced by Tomokazu Seki.
Takeshi Sendo 千堂 武士
Naniwa Gym · Japanese voice: Masaya Onosaka
A featherweight from the Naniwa Gym in Osaka and one of Ippo's fiercest rivals. Brash, fearless and proud, he is a brawler with a strong sense of justice who protects the kids in his neighbourhood. His signature punch is the Smash, a heavy blow thrown from mid range. Voiced by Masaya Onosaka.
Ryo Mashiba 間柴 了
Toho Gym · Japanese voice: Masahiko Tanaka
A tall, quiet featherweight from the Toho Gym with an unsettling presence. He uses his long reach for the Flicker Jab, a whip-like jab thrown from a low hand, followed by a chopping right. He is fiercely protective of his younger sister, Kumi, and meets Ippo during the rookie tournament. Voiced by Masahiko Tanaka.
Ryuichi Hayami 速水 龍一
Otowa Gym · Japanese voice: Kōji Tsujitani
A featherweight from the Otowa Gym who is popular with fans for his good looks and works as a model. He is an out-boxer known for the Shotgun, a fast barrage of punches. He is one of the well-known names in the East Japan Rookie King tournament that Ippo enters. Voiced by Kōji Tsujitani.
Eiji Date 伊達 英二
Nakadai Gym · Japanese voice: Masaki Aizawa
A veteran featherweight from the Nakadai Gym whom Ippo admires. He had stepped away from boxing and came back to fight for his family. Calm and experienced, he reads opponents well, and his signature punch is the Heartbreak Shot, a corkscrew blow aimed at the heart. Voiced by Masaki Aizawa.
Alexander Volg Zangief
Otowa Gym · Japanese voice: Toshiyuki Morikawa
A boxer at the Otowa Gym and one of the most skilled opponents in the Class A tournament. Polite, gentle and reluctant to hurt anyone outside the ring, he becomes a dangerous out-boxer once a fight starts, known for the White Fang, an upward and downward combination. He and Ippo form a lasting friendship. Voiced by Toshiyuki Morikawa.
Mentors
Genji Kamogawa 鴨川 源二
Kamogawa Gym · Japanese voice: Kenji Utsumi
The elderly owner and head coach of the Kamogawa Gym, a former boxer who walks with a cane. He is strict, short-tempered and demanding in training, yet deeply loyal to his fighters. He sees fighting spirit in Ippo early and decides to coach him personally, passing on the punches from his own career. Voiced by Kenji Utsumi.
Supporting characters
Haruhiko Yagi 八木 晴彦
Kamogawa Gym · Japanese voice: Toshihiko Nakajima
The manager of the Kamogawa Gym, nicknamed 'Yagi-chan'. He handles matchmaking, tickets and money and helps with training when needed. Friendly and knowledgeable, he is one of the calmest people around the gym and often explains a boxer's situation to the others. Voiced by Toshihiko Nakajima.
Manabu Itagaki 板垣 学
Kamogawa Gym · Japanese voice: Daisuke Namikawa
A younger boxer who joins the Kamogawa Gym later and looks up to Ippo as his senior. A former high school boxing captain, he is a fast featherweight with sharp reflexes and quick footwork. Cheerful and fond of bad puns, he brings a lighter mood to the gym. Voiced by Daisuke Namikawa.
Kumi Mashiba 間柴 久美
Japanese voice: Sanae Kobayashi
Ryo Mashiba's younger sister. Sweet, modest and shy, she is protective of her older brother and worries about him. She first meets Ippo at a hospital, and a gentle, awkward friendship grows between them, a light romantic thread in the series. Voiced by Sanae Kobayashi.
Hiroko Makunouchi 幕之内 寛子
Japanese voice: Yorie Terauchi
Ippo's mother. A widow, she raised Ippo on her own and runs the family's business with his help.

Voiced by Yorie Terauchi.
Antagonists
Masahiko Umezawa 梅沢 正彦
Japanese voice: Mitsuaki Madono
Ippo's classmate and the leader of the group that bullies him at the start of the story. With two followers, he picks on Ippo until Takamura breaks up one of their attacks. As Ippo changes through boxing, so does his relationship with Umezawa. Voiced by Mitsuaki Madono.
