Hiroko Makunouchi (幕之内寛子, Makunouchi Hiroko) is a recurring character in Hajime no Ippo.
After Makunouchi Kazuo returned with a new boat, he told that when he will no longer be a commercial fisher that stayed out for a while. He can now spend as much time with them from now on. Even though he doesn't know how to run a customer fishing boat, but he believed it suited him more than an office job. Hiroko and Ippo offered to help him with it. However, Kazuo had one last job as a Commercial fisherman before he could start. Hiroko told him to be careful since it looked like there is a storm. A few days later during a storm, Hiroko told Ippo that his father will return in a week, but she was worried the water would be rough and had a bad feeling over it. Her husband was declared lost at sea when he saved Sakuma. After a week of searching he was declared dead.
During the funeral without shedding a tear, she thanked everyone and thought Kazuo would be proud to hear from them. Ippo kept on waiting for his father's return. She tried to get Ippo to come home, but he wouldn't listen. She broken down, and told him there wasn't a point in waiting, but Ippo disagreed since his dad kept his promises. She didn't know what to do, now that her husband was gone until Ippo returned soaking wet carrying Kazuo's cap. Ippo told her his father kept his promise, where he came home. Hiroko decided to live throught it together. She got a captain's license for the fishing boat, while the local fisherman made a sign for it, and offered to help her.
Since Kazuo's death, Hiroko tried to get into dating again, however, nobody sparked her interest. The men thought she would be alone, but she believed she was never alone since she has her son, Makunouchi Ippo. After Ippo saw his mother always tired from working, he mentioned not enrolling in high school, but she told it was unacceptable. She believed he needed to enroll in case he found something else he wanted to do. She told him not to worry bout anything else. She thought if he had time to worry about the business, then he should use it to worry about his future.
When Makunouchi Ippo came home from school, Hiroko noticed he got beat up by students again. When Ippo got accepted to the gym and about to leave the gym for a spar, Hiroko suggested to think of his opponent as a fish, like his father used to. Before Ippo's debut match, Hiroko made a big meal for him and told him that she can't come because of work. Sometime before Ippo's debut match, Ippo asked her to put his name on his new trunks, but gave her an incorrect spelling ("IPO"), which he ended up wearing anyways, since it was too late when he noticed.
At home, Ippo asked Hiroko if she could come see him fight, Hiroko responded that she doesn't want to see her son get hit. Ippo became worried that Hiroko is doing too much work, when Ippo was asked to go to outdoor camp, Hiroko lets him go.
When Hiroko wanted to watch a TV show, Ippo asked her for more time so he can research his next opponent. She asked Ippo if his opponent is strong. Takamura Mamoru, Aoki Masaru, and Kimura Tatsuya visited the house to see Ippo. Hiroko told them that he was sleeping due to a fever as the trio went to his room.
When Ippo got back from the Yamaguchi Chiropractic, Hiroko asked Ippo how it went. Hiroko questioned if he should use medicine instead of a bucket of ice, however, Ippo reassured her that it is the best method. After Ippo won the All Japan Rookie King Tournament, Hiroko got a phone call from him. Hiroko asked Ippo how is his injuries. Hiroko then congratulated him on his victory.
When Ippo came home, Hiroko heard about his entry in the Class A Tournament. When Ippo asked Hiroko if he can go to the training camp, Hiroko let him go. The next day however, Hiroko collapsed due to anaemia from overworking and was sent to the hospital. When Hiroko woke up and saw Ippo, she apologised to Ippo that he could not go to the training camp and wants to close the fishing business. However, Ippo reassured her that he can do it. Two weeks before she was supposed to be released, Hiroko began packing up and go back home. Ippo stopped her, as he wants to continue helping and have boxing as a hobby. When it was time to pick Hiroko up, Ippo and Umezawa Masahiko drove to the hospital and congratulated Hiroko on her release. Hiroko then gave Ippo a new pair of boxing trunks. Hiroko then arrived back home.
The night before the Class A Tournament finals, Hiroko gave Ippo dinner and noted how he only eats a little before a match. Hiroko was then asked how she was feeling, which she informed Ippo that, thanks to him, she fine.
After Ippo's match against Alexander Volg Zangief, Hiroko began to get worried as Ippo has been passed out for three days at the Kawai Hospital. While at the hospital with Ippo, she met Volg, who apologised to her for hurting her son. She peeled Volg an apple, and before Volg left, told him how seeing her son work hard is a wonderful thing for any mother. When Ippo woke up, she informed him that he was sleeping for three days and that Volg came by.
When Ippo came back from a date with Mashiba Kumi, Hiroko asked how the date went and mentioned that since he was 19 years old it was no surprise to hear such things. Later when Ippo returned to the house, Hiroko noticed how Ippo's face looked more of a man's since he lost, as he looked disappointed and embarrassed. She told him that he must really like boxing and to have fun until he gets tired of it.
When Ippo came back from his trip to the mountains, Hiroko asked how the trip went.
When Hiroko heard they had a guest, she rushed to Ippo to met him. Ippo told her that he left, except Shimabukuro Iwao returned after smelling her. She greeted him, and asked if he would like to eat supper with them since he was one of Ippo's friends. Shimabukuro grabbed her hands, and mentioned she had a good smell. Hiroko was worried he had a strange hobby, when Shimabukuro told her that she was a woman of the sea, which confused her. Shimabukuro told Ippo that he must of missed judge him, since he had Hiroko's blood in him making him a man of the sea. He was surprised Tokyo had people of the sea, with it polluted waters. Hiroko was worried that Ippo's been hanging out with a bad crowd, but Ippo told her that it was the first time they met.
Shimabukuro told them his motivation and strength was returning to him, where he was looking forward to their seaman's duel as he was leaving. He asked Ippo if he was a good swimmer, and wondered how long he could last underwater without breathing, but Ippo's told him never tried because of the water there. Shimabukuro agreed, but told him in their match he will take him to the bottom of the sea as he walked away. Hiroko thought he didn't seem bad, just weird. She thought he looked her age, where he was a bachelor, but Ippo told her that he was 22. Later, due to Ippo's intense training, Ippo wasn't able to carry out his duties for the boat. She told him not to push himself too hard since he was told to rest. Ippo mentioned he was okay to work, but she told him it was hard for him to carry the customer's equipment right now.
After Ippo defeated Shimabukuro, Umezawa told her that it was an awesome fight that the newspaper could show, where he thought she should go to one of Ippo's match. Hiroko disagreed, since she didn't want to see her son being beaten to a pulp, where she thought she would have a heart attack from shock. Itagaki Nanako arrived, where she was worried about Ippo since he took a lot of hits in order to see how he was doing. Hiroko told her that he been sleeping the past two days, but he was able to get up to drink and bathroom. She thought since Nanako was a friend, she could go to his room to take a peek, but she warned her that Ippo's face still injured. As Nanako went inside, Hiroko thought it was rare for girls to visit, but Umezawa believed that since Ippo was the champion where he was popular with the ladies. Hiroko thought it was unbelievable that Ippo was popular, but Umezawa told her that he was the hero of Kōrakuen Hall. Mashiba Kumi arrived next, and later Iimura Mari.
When Hiroko arrived to Ippo's bedroom later with tea after she heard them yelling at each other. She told that yelling must make them thirsty. Mari, Kumi, and Nanako thanked her, when Hiroko thought she should be thankful since she had always been proud of Ippo. She added that he gets everyone's attention from boxing, but his strength wasn't why she was proud of him since he's a kind boy, and that was all he needed to be for her. Even the thought of Ippo practicing was enough to worry her, and when he came home with bruised faces too. But when Ippo was so happy every day, there was no way she could ask him to stop boxing. She believed when Ippo is heavily injured, she tries to let Ippo sleep as peacefully as she can. When Kumi, Mari, and Nanako heard that, they were ashamed and decided to leave, while Hiroko told them to return sometime.
After Ippo healed from his injures, he told Hiroko and Umezama that he planned to head to the gym. Hiroko was worried that Ippo was already practicing again, but Ippo told here that he was just going to stop by and check with everyone. Hiroko told Wanpo to go with him in order to make sure Ippo walked. Ippo told her that she didn't need to worry since he knows how important it was to recover from his damage. He promised that he will only walk.
Ippo brought Alexander Volg Zangief to their place, where they were watching Ippo's past matches, and discussing the Dempsey Roll when Hiroko brought them dinner that she fixed. She brought out Nattō since she thought Volg would like it, but he had trouble eating it. Volg mentioned he planned to go to America, but didn't know anyone there, where he hoped Ippo could introduce him to someone. Ippo thought Kamogawa Genji or Fujii Minoru could help, while Hiroko told him that he could stay with them for a few days, and not to worry about a thing. While Volg stayed there, he helped with the fishing boat. Hiroko told him that he didn' need to help, but Umezawa thought that people staying with them need to work. A few days later, Hiroko told Volg to relax while Ippo and Umezawa took the boat out. She wondered if Volg had a request for food to eat, but Volg mentioned he was willing to try anything. Volg thought Hiroko was very kind, he thought Ippo lived in a great environment, where he knew why he was so strong. Hiroko believed Ippo was always so clumsy, but Volg disagreed. He asked Hiroko if he could watch video of Ippo's next opponent since he couldn't read the words. When Ippo returned, she told Ippo that Volg was watching video's, but when they went to check on him, he went out training.
A while later, Hiroko ran into Volg and Wanpo when he was training. She told him that she fixed dinner, and mentioned that Ippo told her that Volg was training more than him. Volg thought Ippo's training was impossible for any boxer to follow. He believed even with all of his training, he didn't think he could win against him. She was surprised when he mentioned that, but she told him that it would be sad when he leaves. She wondered if he will be okay in America by himself, or if he spoke English. Volg thought he would be find, and he was thankful for Ippo and coach Kamogawa. Along the way home, they met Ippo who told them that Umezawa was starving, where Ippo and Volg decided to compete in dashing back, while Hiroko watched. After Volg sparred with Ippo, and over come the Dempsey Roll, Hiroko met with him before he left. She gave Volg a few charms, and some money for helping out with the store. Volg had one request before he left, he asked her to speak some Russian to him. She did, and Volg responded in Russian. She thanked him as Umezawa took him to the airport.
After Ippo defeated Sawamura, Ippo returned home with Kumi walking him back. Hiroko was shocked at Ippo's swollen face, where she thought he had a tough match. She thanked Kumi for walking him home, and offered her tea when Ippo fell down. She put him to bed, thought Ippo must of ran out of juice when he made it home. She told Kumi to comeback when Ippo's fever goes down. She added that she still can't used to seeing Ippo like that, and Kumi could understand since it the same with her brother. Kumi asked about Ippo's father. Hiroko told her that Ippo was a timid boy, if his dad wasn't so reliable, she don't know what she would have done. She wondered if his dad was strong, where Hiroko thought he might have made a better boxer than Ippo. Kumi thought if boy always looked up to his father, the no matter how much she worried about him, he would never stop boxing. Hiroko wondered if she wanted Ippo to stop boxing, and thought it might hard for her to worry about two men. Hiroko felt that no matter what anyone said, Ippo won't stop boxing since she never met a more stubborn man. When Ippo was a kid, when he got something in his mind, he would see it through to the end. She shown Kumi an old cap as proof of it. She started to tell Kumi about it.She mentioned when she saw Ippo soaking wet with the cap, she felt like Kazuo had come home. She thought finding anything floating in the water at night was impossible, when Ippo heard a voice that guided him to it. She believed Kazuo couldn't bear to watch his stubborn kid sitting around waiting any longer. Kumi thought it was amazing, and Hiroko agreed. When Kumi was about to leave, Hirako told her that there was a strange man waiting outside, but Kumi told her it was her brother.
After Ippo's injures healed, and Umezawa finished his his manga, he decided to quit the Fishing Boat and devote himself to be a mangaka. At a farewell dinner for him, Umezawa thanked Hirako for taking care of him, but she thought they should thank him since he helped them a lot. She thought it will be lonely with out him around, but Ippo told her that Umezawa dream wasn't with them. Hiroko told Umezawa to eat up for his arm strength, while Ippo told him to visit. Umezawa felt the need to come clean and apologise to Hiroko and Ippo for what he did in the past when he bullied and beat up Ippo since he wasn't sure on what his relationship with Ippo was. Hiroko told him to lift up his head, and lectured him that if he was going to be stepping into a whole new world, where he can't walk with his head down. He needs to keep his head up, his eyes forward, and do his best. Umezawa thanked while crying. As he left, Hiroko and Ippo discussed they will need to find someone to replace him. Ippo mentioned he will put up some posters for it.
The next day while Ippo visited the gym, Itagaki and Nanako stopped by for the job. Itagaki mentioned that Umezawa called him about it, where Itagaki said he needed the money and the position was a good job for a boxer. Ippo was glad for his help, while Hiroko told Nanako they could only afford the wage for one, but Nanako just there to play around. The next few days Itagaki work on the boat that end up helping his boxing. After Itagaki won his first match in the Rookie King Tournament, Kamogawa Boxing Gym decided to rent out fishing boat with part of the prize money from Ippo's match against Sawamura. Hiroko planned to prepare dinner for everyone with what ever they caught, which started a fishing competition between Yagi, Shinoda, Takamura, Kamogawa, Kimura , and Aoki. They returned early after Takamura fished Aoki out of the sea. Ippo told his mother that they ran out of fishing spots. She cooked the meal for them, and heard about what happened. She told them it was really dangerous for them, and Kamogawa told her that he would take responsibility for since he was with them. As they were eating, they were discussing their future matches that were planned.
Hiroko asked Ippo what he was doing in the hallway after he received a phone call from Miyata Ichirō, who asked about Takamura's potential eye problem.
Hiroko, Ippo, and Itagaki were shocked after they watched Takamura's commercial for Champion Royal C, an energy drink, after Takamura defeated David Eagle. The a few nights later at dinner with Ippo and Itagaki, Hiroko heard about Aoki's new haircut. Ippo thought Takamura got to carried away with his pranks, when another commercial for Takamura appeared advertising Aho Flex, an ab machine. Ippo thought it was strange seeing a boxer on TV, when they aren't fighting, but realised they only ask famous people to do commercials which shows how famous Takamura was. Itagaki agreed, and he wondered how far he will go. Hiroko pointed out they would be more concerned with themselves. She added everyone has dreams, big or small, where they chase after them. People try to see how far they are able to go, which was what makes a man. On the TV, they watch a commercial for Aoki appear where he was advertising Brocooli as Broccoman.
During Takamura's travel across Japan, he called Ippo's house where Hiroko answered. Takamura told her to tell everyone that he was fine. When Ippo asked her if he told her where he was, she mentioned that Takamura was somewhere in the northeast moving down to the east of Tokyo. Itagaki and Ippo discussed the reason why Takamura travelled around Japan. The night prior to Ippo's title defence match against Karasawa Takuzō, Takamura finally returned. Hiroko fixed him dinner, where he told her that he ate different food on his trip, but her food was the best of all as he stole Ippo's and Itagaki's food. Itagaki was surprised at the lack of tension Ippo and Takamura were showing before an important match, but Takamura thought it was against a small fry. Before they got into an argument, Ippo preferred to relax. Takamura mentioned he brought a gift for them, that he bought in Sweet Shop in Osaka. Ippo planned to save it for after the match, while Itagaki, Kimura, and Aoki ate it after they arrived later.
While Itagaki was in the hospital after his match with Imai Kyōsuke, Hiroko saw Ippo carrying more ice chest than usually. Ippo thought if Itagaki heard that the work was hard while he was away, he would probably insist on leaving the hospital to help out. In order, for Itagaki to rest, he thought he needed to pick up the slack for him to rest peacefully. She agreed. After Ippo's match with Take Keīchi, Hiroko was shocked at Ippo's face. She wondered if Ippo would be able to eat. Ippo thought so since they only need rice and miso soup, since he brought the main course (Mentaiko) from Take home with him.
After returning from a fishing trip, Miyazaki mentioned they was able to catch a lot thanks to crew. They told Miyazaki and the other fisherman to leave their gear and supplies and they will carry it for them. Miyazaki was impressed after seeing Ippo carry it all, where another fisherman thought it normal for the Champion, but Ippo told them he been doing this longer than boxing. When Ippo and Itagaki noticed Hiroko trying to carry the heavy stuff, they told her to leave the heavy lifting to them, while she carried the small stuff. Hiroko thanked him for the day, and thought Itagaki was always cheerful as her back started to hurt. She told Ippo that it was a relief to have Itagaki working there as she went inside. After Miyata called of his match with Ippo, Ippo hang around the pier till Mari talked to him. When he returned home, Hiroko noticed Ippo was soaking wet. Ippo told her he was going to change then head out again. He added that he was sorry, but she didn't know what he meant. After he was done changing and leaving, she asked where he was doing. He told her he was going to box.
After Ippo's injures heal from his match with Malcolm Gedo, he was ready to work again. However, a typhoon arrived where Hiroko told Itagaki the business will be closed a for a few days due to the rough weather as Ippo arrived to help. Itagaki mentioned he had something to show Ippo at Kour Hall. A few days later after the storm, when the boat arrived everyone had a big haul as Ippo and Hiroko saw Nanako greeting them offering to help. Ippo believed it was too heavy for her. Itagaki told her they didn't need her help, but Nanako wanted to stay since Kumi was there.
Ippo was watching a video sent by his next opponent. Hiroko asked him what Ippo was watching so intently. She later thought the ocean in the video look beautiful, where she loved to take a vacation there since she thought they could get all kinds of different fish. She noticed the second half of the video was just monkeys and jungle. Later, she decided to go to bed while Ippo continued to watch it. Later on the fishign boat, Hiroko saw Itagaki and Ippo trying to practice shadow boxing on it during their free time.
When Ippo was invited to a class reunion by Umezawa, Hiroko was surprised he was invited, telling her son to have fun as he left.
Hiroko has a slender build and long untamed dark brown hair that is down to her shoulders. She also has dark brown coloured eyes and visible cheekbones at the sides of her mouth.
She is a very kind and strong-willed woman who cares for her son a great deal. Though she refuses to attend any of Ippo's matches because she doesn't want to watch him get hurt, she supports his boxing wholeheartedly because she knows how much joy it has brought to his life and how it has helped him with his self-esteem. She also would always know when Ippo would hide his tears when he came home from school when something happened to him.
- "You want me to come and watch you get punched? ...I'll definitely come when you won't get punched at all." - Round 14, when Ippo asked her to come to one of his matches (to which Ippo thought, "That's impossible.")
