|Anime||Round 79 (S2 - 01)|
|Voice Actor||Inaba Minoru|
A world famous boxing manager, Sakaguchi is infamous for his impure motives and abandoning boxers who fail him. He has had a personal vendetta against Miyata Ichirō since he defeated his client Arnie Gregory to become the OPBF Champion and is willing to do anything to end his career. Sakaguchi bares quite a resemblance in both appearance and personality as the infamous boxing promoter Don King.
After Arnie finish off his sparring partner, Mr. Sakaguchi mentions they are taking applications for future opponents. The reporters mention the match with Miyata Ichirō is already set, but Mr. Sakaguchi mentions that Miyata is sensational, but it is okay since Arnie won't lose. He heard Japan would be a good for business.
After Miyata, they are thinking of fighting another Japanese boxer in Date Eiji or Makunouchi Ippo. Fujii Minoru thinks he is making light of Japanese Boxers. Iimura Mari mentions Miyata's strength is real, and she tells Mr. Sakaguchi that a boxer like his who's proud of his strength will find himself spinning his wheels and the joke will be on him.
Mr. Sakaguchi thinks reporters in Japan are blind. He wanted to keep it as a surprise to everyone in Japan, where they were with holding a souvenir. Although it is disappointing they can't show it at the spar, but it will be revealed during the match for sure, the Bloody Cross
At weigh in, Miyata is at the full limit. Miyata doesn't shake hands with Arnie, and mentions to Mr. Sakaguchi that instead of searching for the next opponent, he should be searching for his next job instead once the match is over. Arnie will not have his belt, and you will also be out of work as his manager.
Mr. Sakaguchi mentions that rumors of Miyata's harsh weight control is appears to be true, and he won't have much strength in the ring, but his counters seem quite excellent, where Arnie should focus on that and teach him a lesson during the 2nd half. Arnie think it won't be a problem. If Miyata tries a counter that will be the end of the match with the Bloody Cross.
After Miyata defeated Arnie, develops a grudge for Miyata and condescendingly yelled at Arnie for losing.
He returned again with another pawn from Thailand, Medgern Dachboy. Sakaguchi made a promise to Dachboy saying he would help his sick daughter if he could last all ten rounds with the OPBF Champion Miyata Ichirō, and that winning didn't matter. But during the course of the match, Dachboy grew excited and wanted to have a serious and man to man battle with Miyata. He went all out against Miyata and even after being nailed a few times by his counters, he kept fighting. In a last resort attack against the champion, he was sent flying by Miyata's Counter. After the fight, Sakaguchi claims to have discovered the "greatest flaw in Miyata's boxing".
Mr Sakaguchi makes a reappearance during Miyata's fight against Che Jounbong. During the 3rd Round, Miyata notices a familiar face in the crowd, Mr. Sakaguchi. He also notices a person (Randy Boy Junior) sitting next to Mr. Sakaguchi that looks familiar to him, but can't place him. Miyata starts thinking about who that person might be, and he becomes distracted in his match allowing Che to land some punches on him. After the match, RBJ meets Miyata to try and arrange a fight.
RBJ meets Mr Sakaguchi outside and mentions Miyata turned him down, but Mr Sakaguchi mentions not to worry, he will get that match for him. RBJ mentions if Miyata's fists weren't broken, he wonders what would have happened. After hearing that, Mr. Sakaguchi knew how to arrange their match now.
After Miyata's match against Donnie Sultan, Ippo runs into Mr. Sakaguchi. He want try sign Ippo to a contract, but Ippo turns it down. Mr Sakaguchi ask Ippo if he want a World title, the one condition is that you beat his boxer, Randy Boy Junior - the New OPBF Interim Champion. Both of them are aiming for a World title match, Ippo and him will clash and he would like to Promote it. Ippo has nothing to discuss with him since he doesn't think Miyata will lose.
Mr. Sakaguchi laughs, and comments that Ippo doesn't know their history. He tells Ippo to look up and see, Miyata has no chance of winning. Mr. Sakaguchi saw, and it only made him more confident. Counters will be useless. History has already proven it.
After defeating all the boxers at Otowa Boxing Gym, Randy Boy Junior is having a hard time finding training partners. Mr. Sakaguchi mentions that they should have gone to Mexico instead of training in Japan. When Mari asks why he didn't, Otowa Coach mentions it was because he was too cheap. Mr Sakaguchi ask if there is any other gyms they could call, that had a fast fighter (to prepare for Miyata, and to show off.) Otowa Coach doesn't think so when they hear about Randy Boy Junior destroying boxers. In order to find someone to eat his words, they begin to think of potential opponents for him. Mari thought of Itagaki.
Itagaki ends up fighting RBJ in a spar (with Ippo following along) and he loses. Ippo steps in the ring wanting to fight. However Sakaguchi breaks the fight up, saying he previously offered him a chance to fight Randy but he declined. After the spar, Randy Boy confronts Mr. Sakaguchi about it, only cares if he is able to delivers a World Title match later.
After Randy loses he claims he will never return to Japan again and then takes a bowel movement in the restroom and does not flush. Takamura happens to pass by and accidentally hits him in a fit of rage. The newspaper the next day has a headline of Sakaguchi saying he's never coming to Japan again, which causes Miyata to sigh in happiness.
Mr. Sakaguchi is the smallest adult in the story. He typically has a white mustache and white bushy hair and eye brows (similar to Don King.) He is typically seen wearing a business suit.
Mr. Sakaguchi tends to be arrogant, and looks down on people. When he first came to Japan, he tend to be over confident in his boxer's ability, and looked down on Japanese boxers and people. Mr. Sakaguchi tends to be petty, and he will carry a grudge if he is wrong, as his feud with Miyata has shown. He is willing to use his money or influence to get his way.
He is strongly interested in money. It was mentioned he could have took Randy Boy Junior to Mexico to spar with other boxer, but in order to save money, he took him to Japan instead. He tried to get Ippo to sign a contract with him, but Ippo refused.
- He has a lot of similarities in his managing background as real life retired boxing manager/promoter Don King.
