After the War Arc

Kamogawa Genji

Kamogawa Genji in his Younger Appearance

Kamogawa worked as a prizefighter in Japan shortly after the end of the Second World War. He has had multiple boxing matches with former prizefighter Nekota Ginpachi, two of which he lost, two of which he won, and another that ended a draw. He was also friends with fellow prizefighter and future trainer Hama Dankichi. During the American occupation of Japan, Kamogawa harboured strong feelings of national pride, refusing to accept food handouts.

Kamogawa witnessed American sergeant Ralph Anderson easily defeat Hama in an exhibition match. After Hama's loss, Anderson terrorised the population and chased Yuki into the alleys. Here, Kamogawa experienced the power of American boxing first-hand as he and Nekota were beaten up by Anderson while protecting Yuki. After seeing Anderson's clinical jabs and being hit by a Cross Counter, Kamogawa acknowledged that American boxing was at least a hundred years ahead of Japanese prizefighting. It was also here that he encountered Miguel Zale, a soldier and second to Anderson.

During this time, Yuki and Nekota moved into Kamogawa's makeshift home. Yuki looked after the pair while they trained, inspired by their commitment to rebuilding the country through their fighting spirit. However, Kamogawa discovered that Yuki was a survivor from Hiroshima, who was dying from radiation poisoning.

Although Kamogawa's pride was hurt, he was aware of the gap between Japanese prizefighting and American boxing, and declined to challenge Anderson on the basis that true boxers fight against their own weight division, and as a bantamweight, Kamogawa was no match for Anderson. However, Nekota secretly arranged a fight with Anderson. Kamogawa furiously rushed to the match after realising Nekota had been brain-damaged after their last fight together. Despite Nekota's superior speed, he was crippled by an illegal Rabbit Punch and was severely beaten before Kamogawa interfered and stopped the match.

Swearing to avenge Nekota, Kamogawa trained by punching a log into an embankment, honing his fists into a deadly weapon. In the match against Anderson, Kamogawa was outclassed and unable to land a clean hit. Through the strength of his spirit and Nekota's desperate encouragement, Kamogawa absorbs Anderson's chopping right and lands two deadly body blows, breaking his ribs and puncturing his internal organs. Despite defeating Ralph, Kamogawa broke both his fists in the process, which ended his career thereafter.

With Nekota retreating to his mountain home to recover, Kamogawa put aside the feelings between himself and Yuki and dedicated his life to passing on his passion for boxing.

Sometime later, Kamogawa opened his own boxing gym, where he trained the future manager of the gym Yagi Haruhiko, the then-OPBF Featherweight champion Miyata Senior, and the budding counter specialist Miyata Ichirō. By chance, he encountered Takamura Mamoru and convinced him to enter the world of boxing under his tutorship.

Part I

Early Days Arc


Kamogawa helping Ippo during his spar.

One day, Takamura Mamoru brought over a newcomer named Makunouchi Ippo. Kamogawa was sceptical about the idea of Ippo becoming a professional, due to his appearance and attitude. In order to conclude what his chances were, he decided to have him spar against boxing prodigy Miyata Ichirō. During the spar, Ippo went down several times and was unable to land a single hit on Miyata before losing via knockout. However, his durability, stamina and determination, earned Kamogawa's respect and a membership to his gym.

Kamogawa decided to supervise Ippo's training personally (which he did for no one other than Takamura) and announced that he would have a rematch against Miyata. During the months leading up to the rematch, Kamogawa taught Ippo how to perform an uppercut, and put him through intensive training in order to directly face the counter instead of avoiding it. In an attempt to have both aspiring boxers motivated, he instigated a rivalry between them, by constantly making comments about Ippo's growth. Kamogawa is Ippo's second on his second spar with Miyata. After Ippo won, Kamogawa had to hide his excitement. Kamogawa is impressed after receiving a picture of Ippo hitting the tip of Miyata's jaw from Fujii Minoru.

As Ippo "lost his goal" after sparring with Miyata, he no longer showed his punching power while mitt training with Kamogawa, seeing this, Kamogawa ordered him to train with Takamura in order to understand the hardships of the sport. Kamogawa is Takamura's second in his match against Hirano Kazuhiko, where Takamura wins and gets ranked first in Japan. Kamogawa announces that Ippo's opponent for his pro debut is Oda Yūsuke. In the match against Oda, Kamogawa avoided a doctor stoppage by applying ice and lotion to Ippo's cut allowing him to continue the fight which he ultimately won via knockout. After Ippo won, Kamogawa silently walked away and left Ippo and the others money to celebrate.


Kamogawa during Ippo's match with Fujiwara.

Kamogawa began to teach Ippo the Peek-a-Boo Style in order to heighten his defence. Kamogawa announced Ippo's second opponent as Fujiwara Yoshio and told him even with a one win and one loss record, anything can happen in boxing. Before the match began, Kamogawa told Ippo to do as practice and there will be no problem. After Ippo's win, Kamogawa congratulated him on his victory, and then laughed at Ippo's bump on his head.

Rookie King Tournament: First Rounder Arc


Kamogawa and Yagi learning about Ozuma sending his sparring partner to the hospital.

After Jason Ozuma was revealed as Ippo's first opponent at the East Japan Rookie King Tournament and hearing about how he put his sparring partner in the hospital with a hook, Kamogawa decided to have Takamura train Ippo to dodge hooks. On the day of the match after round one, Kamogawa told Ippo that his punches are getting to Ozuma and to not show pain in his face. After Ippo's down in round two, Kamogawa helped him get up by yelling. Kamogawa noticed the training paid off as Ippo won his match.

As Kamogawa watched tapes of Kobashi Kenta and Hayami Ryūichi's matches, he concluded that Ippo now has two obstacles to pass to get to Miyata. Kamogawa sent Ippo, Takamura, Aoki, and Kimura to a one week training camp session. When the group came back, Yagi showed everyone the poster of Takamura match against the Japanese middleweight champion and Ippo's match against Kobashi Kenta. Ippo began sparring with Kimura as Kamogawa noted Ippo's feet and weight shift has gotten better. When Ippo explained that Kobashi was observing him and that he might have a secret weapon, Kamogawa suggested to not care about the opponent and to focus on bringing destruction into play.

When Ippo's match against Kobashi began, Kamogawa noticed how bad Ippo was sweating during the match and how they both fell into Kobashi's trap. However, after Ippo found a chance for a hit, he and Kamogawa won. Kamogawa then acted as Takamura's second during his Japanese middleweight champion title match. After Takamura's win and winning the JBC middleweight champion belt, Kamogawa and the others celebrated.

Rookie King Tournament: Finals Arc

Kamogawa shows Ippo a recording of Hayami's match, showing Ippo's original plan was not going to work. Kamogawa told Ippo that in order to defeat Hayami, let him use the Shotgun and then attack while he is exhausted, Kamogawa then put Ippo on defensive training. When Aoki had a match that was after Ippo's next opponent, Hayami Ryūichi, Kamogawa was one of his cornermen. The match ended with Aoki winning. After Ippo told Kamogawa he wanted to learn how to throw a counter when Hayami uses his uppercut, Kamogawa began training Ippo for counters. On the day of the match, before Ippo was about to fight, Kamogawa told him to use the counter only once. Ippo then won the match against Hayami.


Kamogawa and Ippo after winning the tournament.

After Ippo damaged his fist, Kamogawa told him not to use it for two weeks. Kamogawa explained Mashiba Ryō's weakness in his Hitman Style, which is his left guard always being down. On the day of the match, Kamogawa told Ippo to keep the match an in-fight in order to keep close to him. After Ippo won the match, Kamogawa was proud of Ippo winning the tournament.

Phantom Card Arc

During Itagaki's match against Imai Kyōsuke, while Itagaki Manabu catching his breath in the 4th round, Shinoda Tomoyuki tells Itagaki to drink some water and listen close since he is going to say the ultimate words to perk him right back up again. Itagaki wonders if there are such words, and wonders what they are. Shinoda is hesitant in saying it, but he tells Itagaki "With Guts, Go Gattsun, Gattsun!!" The corner is shocked at Shinoda's bad pun. As the round is about to begin, Itagaki tells him "I'll go hang in there Shinoda-san!" (Shinoide, Shinoda) After that, Shinoda repeats his pun, where the crowd can hear him.

During the Round, Kamogawa tells Shinoda that Itagaki will return, and to have some words to cheer him up, but Shionda's run out of idea's. They ask Yagi instead. Imai and Itagaki continue to slug it out, but Itagaki doesn't fall and continues to show his determination to the round ends. When Itagaki makes it back to the corner, he falls down but Yagi Haruhiko manages to put the chair down in time for him. Yagi tells them about it as a pun, "This Isu Naisu!" (This chair/is nice.) However, Shinoda and Kamogawa tells him they have no time for such dumb comments. Itagaki manages to hold on till the end to take it to decision. The Judges rule in favor of Itagaki.

After the match, Ippo, Yagi, and Kamogawa leave the building they talk about the West Japan Rookie King, when Sendō Takeshi arrives mentioning that he nothing special. Ippo asks why Sendo is in Tokyo, and he mentions checking out the enemy. He introduces Hoshi Hiroyuki, who won the West Japan Rookie King the other day. He wants to challenge Ippo, but Ippo warns him that Itagaki is strong. Hoshi mentions if he defeats Itagaki, Ippo will acept his challenge as he leaves.

Kamogawa notes that Hoshi has nerves of steel, and Ippo thinks it could be tough on Itagaki. Kamogawa warns him the head that he is aiming for is his. Guys like that are going to rising higher from now on, if Ippo gives them the chance they will catch him off guard. Kamogawa tells him to keep defending the title, he will need to concentrate and concentrate. Ippo asks how long he needs to keep defending the title. He mentions remembering his past goal of the East Rookie King Finals of fighting Miyata, and how Miyata is waiting for him. He wants to relinquish the Japanese title. Kamogawa tells him he will inform the boxing commission of his intention to relinquish the title in a few days and at the same time to throw a challenge to the OPBF champion.

Veteran Card Arc

Kamogawa calls Kawahara Boxing Gym to speak to Coach Miyata about arranging Ippo's match with Miyata Ichirō. Miyata Senior knows what the call is about, and Kamogawa mentions that both boxers feel the same way about it, if they postpone it any longer, they will lose their motivation. It's time. Miyata Senior mentions that Miyata got a title defence set in two months, if he can clear that, he is free to fight Ippo. They agree on Spring. Miyata Senior mention the promise he made when they left Kamogawa Gym taht someday, they would meet again. A match between Ippo and Miyata is their promise land. This unworthy soul's apprentice will lead us all to the land that surpasses his master. Kamogawa tells him to stop kidding around, while Miyata Senior tells him to see him in the Spring. Kamogawa mentions to Yagi that he knew the day will come, and it here. He excited about it.

The next day, Ippo stops by while Takamura Mamoru is talking about the gyms new warcry, With Guts, Gattsun Gattsun. He mentions the moment was almost ruin by Yagi's pun, This Isu Naisu. When Kamogawa arrives he wonders what the ruckus is about. Yagi complains about them making fun of him, but Kamogawa mentions it was Yagi-chan's fault, while Kimura Tatsuya, Aoki Masaru, and Takamura die laughing. Kamogawa tells him that is enough, it's true that it was a big failure, but making fun of their superior is the height of insolence. He going to make them go through hellsih training to knock their attitudes back into shape. He tells Yagi to decide, and to show them what he is made of. Yagi tells them 10 mins without rest to hit the sandbags, they will do it 3 times, hit the sandbag 3 times (Sandobaggu Sando), which causes Takamura to laugh and Kamogawa to hit him for making another pun. Kamogawa tells Ippo to see him in his office, while everyone else trains.

Kamogawa tells Ippo to be calm to listen, but Ippo's too excited since it means he match with Miyata is decided, however Kamogawa tells him his next match will be at the champion carnival at the beginning of the year, where he is defending the time. Disappointed Ippo start to leave, when Kamogawa mentions that the match is set for January 25th, two days before Miyata's OPBF title defense. If Ippo doesn't have a match until spring, he would have gone 1/2 a year without a match. A blank will hurt him against Miyata, who is the number one boxer in the Pacific.

Yagi mentions they matched up our schedules with the OPBF Champions. Kamogawa adds his desired match is unofficially set for spring. He tells Ippo they matched the schedules so the time they will have to prepare for the match is the same, where there will be no handicaps for it. He asks Ippo if he will do it, and Ippo agrees. Kamogawa tells him to remember it's not official yet, so if either of them loses their defense that will be the end of the matter. After Ippo leaves, Yagi Haruhiko and Kamogawa discuss it. Kamogawa notes that most people will be interested in the fact that both of them are World Rankers, where the words on the poster will all but write themselves, "Their last battle before the world."

Later on, Kamogawa is discussing Ippo's next opponent, Take Keīchi, with Ippo. He mentions he never since Take fight, but it appears he's never been KO. Yagi mentions Take seems strong at taking punches. Kamogawa proceeds to train and prepare Ippo for the match. After mitt training, Kamogawa mentions Date makes a great leader to Takamura for warning Ippo about Take, since he planned to knock Ippo out of his fixation on his match with Miyata. Kamogawa notes that Ippo's hasn't fought against many veterans aside from Date. Takamura notes that Date only had 20 matches, while Take has over 30.

Kamogawa mentions Take probably has quite a few methods to wear down on young fighters, where it will be hard for Ippo to fight with his own rhythm for the entire match. Takamura thinks with Ippo's rhythm broken, even Ippo's mind could break, where he could end up losing. Kamogawa tells him noting adds more fatigue than a broken rhythem, so they are working on Ippo's stamina. It will help him control the fight early on.

During the weight in, Kamogawa is complaining about Take being late. When he sees Take come in looking sick. After it the weight in, Ippo comments on it, but Yagi starts laughing while Kamogawa tells him it was a textbook ruse. He was faking it since he didn't let Ippo get close to him to confirm it. Kamogawa mentions that even for a veteran to try a move like that was gutsy. He thinks it ws pathetic in this day and age, no one is gullible enough to fall for that. Mental games will never get any admiration from him, and the fact that he showed up late is pathetic. Yagi notes that the coach may have fallen for it more than either of them. Kamogawa tells Ippo to go in running from the opening gong to destroy his worthless tricks with his power. Kamogawa proceeds to coach Ippo in defeating Take.

After Miyata's match, Kamogawa tells Ippo that his match with Miyata had been called off due to injuries he received in it. Miyata broken both of his fists, where it will take time to heal. Upon recovery for the OPBF title match his return match, they decided that they will give Ippo priority as the first challenger. So the match is not canceled, but postponed.

File:Ippo mitt training with Kamogawa 2.png

When Ippo visits the Kamogawa Boxing Gym, Kamogawa greets him and is immediately hugged by the ecstatic Ippo. When asked about why he is wearing mitts, Kamogawa tells Ippo he is starting serious training for Takamura. While Yagi was the original mitt practising partner, Kamogawa tells Ippo to get ready for practise. When ready, Ippo begins mitt training with Kamogawa, who believes Ippo hasn't lost his edge. Kamogawa tells Ippo to go faster. However, Kamogawa is not able to keep up with him, noticing that Ippo has gotten stronger. After the mitt practise, Kamogawa asks why Ippo came over. Ippo replies that he wanted to borrow mitts to train Taihei. Kamogawa gives Ippo his old pair that he used to catch Ippo's fists when he first started. Ippo leaves the gym, promising he'll come back.

A bald Ippo comes into the gym and asks for Kamogawa in order to say his apologises. In Kamogawa's office, he returns the mitts, saying that he's not apt to be a leader nor qualified to wear the mitts. Ippo requests to be exiled, however Kamogawa states that exiling isn't enough. Kamogawa has the first atonement being to clean the gym for three months, while the second is to train Taihei and Kintarō Kaneda.

  • Kamogawa's Appearance
  • Kamogawa's in his "Dynamic Glove" navy blue long-sleeved shirt.
  • Kamogawa's younger appearance

During his youth, Kamogawa sported messy, dark-brown, hair and a muscular physique. He also had a very rigid face structure, with a bulky isometric nose and large eye-brows. This refined jawline is less prevalent in his older years.

In his twilight years, Kamogawa is partially bald with grey hair residing on the sides of his head, as well as an unusual small clockwise spiral of hair above his forehead. He also has large grey eyebrows and a large nose. His age leaves him with liver spots and wrinkles. It also leaves him often walking with a brown wooden cane.

His attire at his gym and during matches usually consists of a white long or short-sleeved shirt with a small "KBG" in black letters on the front in the top-right corner, and "Kamogawa Boxing Gym" in big black letters on the back along with black pants and shoes. Sometimes outside the gym, he wears a brown suit with a red tie, brown fedora, pants and shoes. Sometimes during matches he wears a navy blue long-sleeved shirt with "Dynamic Glove" in big white letters on the front, black pants and red shoes.


Kamogawa is fairly stubborn, stoic, and introspective, rarely displaying his emotions outwardly. He is deeply passionate about boxing as a sport and takes great pride in his boxers success. Despite this, he is prudish and does not tolerate indecency and debauchery, disciplining his disciples with his cane when they step out of line. He only yells at people who he has hopes for and deems dependable[2]..

He is repeatedly proud of Takamura and Ippo, though he rarely expresses it. It is Ippo who he regards as his "last son". He seeks to raise a world champion whose boxing is principled on fighting spirit, not just talent or skill.


Back in his prime days as a Bantamweight, Kamogawa was a right-handed hard fighter. Nekota once stated that Kamogawa's right and left hasn't faded in his old age, implying that Kamogawa used both Southpaw and Orthodox Boxing Styles.

He invented Tekken, a destructive body blow which leaves an imprint of a fist behind. He possesses a stubborn and unyielding fighting spirit, which he seeks to pass down to a successor in the hopes of challenging the world. His strong willpower allows him to continue fighting even the toughest of opponents.


Kamogawa has vast intelligence in boxing, knowing many techniques, styles, and boxers from the real world. He is able to quickly recognise many techniques as a boxer is using them, such as when he saw Ippo's Dempsey Roll for the first time. His boxing knowledge allows him to quickly come up with strategies to counter an opponent before and during matches for his boxers.



  • "I expected someone who could become a pro because you recruited him, but what is that? I don't feel any fighting spirit!" - To Takamura the first time Ippo joined the gym
  • "Not everyone who works hard is rewarded. But! All those who succeed have worked hard!" - To Takamura before his fight with Bryan Hawk


  • Kamogawa has been seen only once smoking a cigar in the series. [3].
  • As of Chapter 1012, Kamogawa is still able to do mitt hitting with Ippo and Takamura consecutively at his old age.
  • Kamogawa caused Hama Dankichi's Glass Jaw injury, and responsible for Nekota Ginpachi for being Punch Drunk.
  • In the manga, there is a page that shows Kamogawa and Nekota Ginpachi as fighter pilots during WWII.
  • Kamogawa was arrested in the story, prior to Ippo's match against Malcolm Gedo, but the charges were later dropped.
