Otokojuku (男塾 Man Private School?) is a private boy's school in Tokyo, established over 300 years ago. The headmaster Heihachi Edajima gathers delinquents from all over Japan and trains them to become the leaders of the next generation.
Amongst the students, the first years are viewed as slaves, the second years as oni, and the third years as Enma. The third years take instruction from the headmaster alone, as the rest of the instructors are not at the same level as them and can not outpower them enough to punish them. The third years run things from the Tendo Shirne (天動宮?), and will tour all over Japan in order to settle disputes.
Anyone who fails to do anything in Otokojuku must undergo a Otokojuku Specialty (男塾名物 Otokojuku Meibutsu?). The outside world is told that these are average school events and special lessons, but in actuality they are various torture methods and duels. A few specialties are known of outside the school, as evident when Hidemaro knew of the Oil Bath before enrolling.
- Chokushin Kougun (直進行軍 Non-Stop Marching?)
- Abura Buro (油風呂 Oil Bath?)
- Chikurinken Sumou (竹林剣相撲 Bamboo Forest Sword Sumo?)

Kyoura Daiyon Kyousatsu
(驚邏大四凶殺, The Four Great Astonishing Assaults)
Otokojuku's greatest specialty, used to settle disputes between two teams of four. The entrance is the 1,000-year-old Fujiyama-roku Hougokuin (富士山麓宝獄院 Mount Fuji Foot Treasured Hell Temple?), which leads to the skeleton and corpse littered Anryoudou (暗魎洞 Dark Spirit Cave?). And the end of it is two giant iron balls called the Houkongyoku (砲魂玉 Cannon Spirit Ball?), which must be rolled up to the summit of Fujiyama. At the check-points, each team chooses one representative to take part in a fight. Whichever surviving side wins in the end is awarded the Shouhyoukan (勝彰巻 Victorious Shadow Scroll?) as champion.
Edajima is the only survivor in its 300-year history, having achieved a magnificent victory 50 years ago in 1950 (Showa 25). Inside Otokojuku is a memorial stone monument in honor of those who lost their lives.
- Shakumyaku Ioukan (灼脈硫黄関 Scorching Sulfur Vein Gateway?)
- A fight at one of Japan’s three great sulfur springs, the Fuji Shaku Gousen (富士灼獄泉 Fuji Scorching Hell Spring?). The footing is only countless protruding rocks scattered across the place, and those that fall end up in a thousand degree temperature manganese acidic sulfur spring. Site of J vs. Raiden.
- Dangai Chuurankan (断崖宙乱関 Violnet Midair Cliff Gateway?)
- A fight on Fuji’s 5’th side, the Kengen no Heki (懸厳の壁 Wall of Dangling Severity?). Both men dangle from a rope with no footing, but the rope itself is made of steel, so there is no chance of it breaking. Site of Togashi vs. Hien.

Site of Toramaru vs. Gekkou.
- Choukyou Taisou Kafunkan (頂極大巣火噴関 Great Erupting Summit Gateway?)
- A fight in the Tenjoutou (天縄闘 Heavenly Cord Battlground?) which lies on a large crater on the summit of Fuji. The spider-web shaped Tenjoutou is made of the Sekimenkou (石綿綱 Asbestos Rope?) which is ignited in flames from all sides during the fight, the two fighters compete as the flames draw nearer and the footing becomes unstable. Before the battleground falls the crater bottom becomes the Sekisanko (赤酸湖 Red Acid Lake?), filled with a large amount of poisonous hydrogen chloride gas. Site of Momo vs. Date.

It is Otokojuku's greatest fighting event, and whoever controls the Dai Ishin Pa-Lien Seiha also controls Otokojuku. The previous champion team chooses their opponent team, and Jaki has used this tournament to maintain his authority over the past 10 years.

He is fluent in multiple languages and is a master of various secret techniques, always wears a white hachimaki, carries around a katana, has a laid-back attitude and sense of humor and often dozes off during class. Very little is known about his past or how he got so strong. In the past, he trained at a temple to learn the Shoukyuu Soudan, and his son Shishimaru in Akatsuki!! Otokojuku underwent the same training. After graduating from Otokojuku, he enrolled in University of Tokyo, and after that he studied abroad at Harvard University. In Akatsuki!! Otokojuku he works for the Prime Minister of Japan.

- Shinganken (心眼剣 Mind's eye Blade?)
- An iai strike performed while blinded.
- Ichinotachi (一之太刀 Single Tachi?)
- Used in the fight against Shu Kougen. Momo covers his eyes with his hachimaki, draws a circle in the snow with his own blood, and strikes anyone he senses entering it.
- Shishi Tourouken (四肢鐺瓏剣 Quartered Heated Dragon Blade?)
- When an opponent with a katana strikes continuously, Momo strikes at all of their limbs and steals their fighting spirit.
- Hishou Kakusui Ken (秘承鶴錘剣 Secret Crane Spindle Blade?)

- Shinkifuukon (暹氣虎魂 Rising Tiger Spirit?)
- Momo concentrates his ki into his sword blade and sends out a shockwave in the shape of a tiger. Because the overwhelming destructive power exhausts so much ki, it can only be used for a short period of time.
- Kikoutouhou (氣功闘法 Ki Battle Tactics?)
- Battle tactics that rely on ki. When Momo exhausts a large amount of physical strength, his ki runs out as well and he sweats profusely.
- Koufuken Saikou (硬布拳砕功 Stiff Cloth Fist Attack?)
- Momo injects his hachimaki with his ki and can use it as a blade for an instant.
- Kensai Taikou (堅砦体功 Strong Fortress Body?)
- A defense technique where Momo focuses all of his ki into his chest. For an instant his chest becomes like an iron plate, and not even Jaki's Shinkuu Senpuu Shou can hurt him.
- Shoukyuu Soudan (翔穹操弾 Soaring Manipulation Bullet?)
- A secret attack where Momo can freely manipulate his opponent's entire body. Momo was one of three successors to the technique, but because the technique is rather cruel and meant for trifling with opponent's lives he usually keeps it sealed away. See Sou Reigen for more information.
(富樫 源次, Togashi Genji)
Voiced by: Ken Yamaguchi. The leader of the Otokojuku Shock Corps and a close friend of Momo since the beginning of class. He is a brawler and uses a dosu knife. He always wears a tattered school hat, which is a memento from his late older brother Genkichi (Voiced by: Michihiro Ikemizu) who was killed years ago in the same battleground where Togashi fights Senkuu. He has a scar underneath his right eye from a fight 3 years before enrolling in Otokojuku. He does not have any formal martial arts training, but he shows an incredible fighting spirit. Although he has great fights against Hien and Senkuu, he later becomes a comical character and mostly serves as a commentator with Toramaru. He is well known for risking his life and seeming to die, only to return alive and well later. In Akatsuki!! Otokojuku he has become Edajima’s secretary. Additionally, his father, Genzo Togashi, appears in Peerless: The Legend of Edajima Heihachi as an ace pilot for the Imperial Japanese Navy.

(虎丸 龍次, Toramaru Ryūji)
Voiced by: Yūsaku Yara. A comical guy with herculean strength and a big appetite. He claims to practice Mouko-ryuu Kenpo, but in actuality it is just his own style of Kenpo. Because he farted in the face of an instructor the day he enrolled, he was accuses of treason and forced to hold up a 200 kg suspended ceiling for half a year. Although initially depicted as strong enough to knock out Momo and break off a piece of the ice ring with a single punch, he later mostly serves as a commentator with Togashi. Though he accepts this position and even calls himself the "Eternal Commentator of Otokojuku", whenever he does fight again he fights bravely. His specialty is sumo and he was a yokozuna back in his hometown. He will often fight wearing only his fundoshi. His father Ryuta appears in Peerless: The Legend of Edajima Heihachi in a maximum-security army prison, holding a suspended ceiling, the same way his son was introduced.

Originally depicted as one of many students who came to Japan to study abroad, after his fight with Momo he enrolls in Otokojuku. His full name is King Battler Junior (キング・バトラー・ジュニア?) and is the son of the well known boxer King Battler. He has several times faced an opponent who was confident in their victory against him, only to be defeated in a come from behind victory by a new blow.

(極小路 秀麻呂, Gokukōji Hidemaro)
Voiced by: Noriko Tsukase. A bratty yakuza successor who is enrolled in Otokojuku after his group crumbles due to his profligate ways. He is frequently teased for his short build, but obtains a form of personal growth by hoisting Otokojuku's massive school flag. In the anime, he disliked pro wrestling before entering Otokojuku. In the manga he refers to himself in the first person as boku (僕?), but in the anime he says ore (オレ?).
The live action film focuses a lot on his experience after enrolling in Otokojuku, making him a sort of second main character after Momo.
(松尾 鯛雄, Matsuo Taio)
Voiced by: Juji Matsuda. The comic relief character along with Hidemaro and Tazawa, he is also the lead yeller and bell ringer in the school's ōendan. He has an odd hairstyle, similar to the title character in Sazae-san. His bad premonitions often come true. His father, Koisachi Matsuo, appears in Peerless: The Legend of Edajima Heihachi as a similar comic relief role.
(田沢 慎一郎, Tazawa Shinichirō)
Voiced by: Masato Hirano. The self-proclaimed "Intelligence of Otokojuku". He is also called the "Brains of Otokojuku", but he often messes up simple things like multiplication tables, making his knowledge questionable. However, he does have rare moments where a glimpse of true intelligence can be seen from him. In the Dai Ishin Paren Seiha Arc, it was his idea to form the "10,000 Man Bridge" human bridge. He was renamed Ippei Tazawa (田沢一平 Tazawa Ippei?) in the anime. His father, Tazawa Shintaro, appears in Peerless: The Legend of Edajima Heihachi, and much like in the original series he serves as part of the comic relief duo with Matsuo.
(椿山 清美, Tsubakiyama Kiyomi)
Voiced by: Kazuhiro Nakata. A large student with a rather timid personality. He enrolled in Otokojuku to become more manly, but because he can't endure the strict training he tries to run away, only to be caught by Umanosuke Gonda, who then fights him in the men's dorm specialty match Chikurinken Sumou (竹林剣相撲 Bamboo Thicket Sword Sumo?). Midway through the match he learns that Gonda had made yakitori out of his pet Pee-ko (ピー子?), so he becomes enraged and avenges the little bird. After this he gains confidence in himself. Snow is his weakness. In the anime, he is a regular character from the first episode on and also has more lines.
2nd Year Students
(赤石 剛次, Akashi Gōji)
Voiced by: Katsuji Mori. The strongest of the Otokojuku 2nd Years.

It is a very sturdy sword, the only time it ever cracked was when it was hit by J's Magnum Steel Knuckle. He has silver hair, although it was changed to black in the anime.
Both first and second years fear him, and even the third years recognize his great skills. He fights as a supporter for the first time in the Tenchou Gorin Dai Bukai finals. After his fight against Hornet in the Battle of the Seven Tusks, he uses his Zanganken technique in order to save the other Otokojuku students from a trap and then dies. He entrusts his katana to Momo.
After the series ends he is confirmed to have lived. His son Juuzou appears in Akatsuki!! Otokojuku.
Voiced by: Ginzō Matsuo. The leader of the 2nd years in Akashi’s absence. Depicted as the main tormentor of the 1st years, he usually wears an overly forced smile, but when mad his face changes to one of a furious psychotic killer. In Akatsuki!! Otokojuku, decades have passed but he has yet to graduate and therefore is still enrolled in Otokojuku.
Other 2nd years
3rd Year Students

Voiced by: Hideyuki Tanaka. The leader of the third years and the Otokojuku representative. Known as the Emperor of Otokojuku, he has ruled the school for over 10 years.

He has won the Dai Ishin Paren Seiha three consecutive times, and he uses his power to defend his position. In the past he challenged Edajima to a duel but suffered his first loss, and came to realize the level of Edajima's greatness.

He joins Jaki in the final battle of the Paren Seiha in the Tenrai Kyoushintou against Momo & Gekkou and defeats Gekkou.

He is initially depicted as very masculine and often sweating, but is later depicted as a man of beauty, often holding a black rose in his mouth. He can use the rose as a weapon, but he is never actually shown doing so. He dislikes killing and always tries to avoid actually stabbing his enemies. He also shows respect to enemies who are willing to die to win, and even saved Togashi's life after defeating him.

He claims to be the one who killed Togashi's brother Genkichi.
During the battle against Rouroukan in the Tenchou Gorin Preliminary League he attacks Sou Reigen, but Sou Reigen destroys his poison eye with his Shoukyuu Soudan and breaks his spine, killing him. He is the first Otokojuku fighter to die.
In the Paren Seiha he displays a sadistic personality disorder by viciously attacking Hien repeatedly, but he is actually a shy and gentle person despite his huge body and grim face. In the anime he wears an eyepatch.

From his first appearance to the Paren Seiha he had puffy eyelids and the face of a sarcastic senpai character and used cowardly tactics, but in the Tenchou Gorin his face was more slender and attractive. His tactics also changed, and he started using frontal attacks during his Kousou Henjutsu technique.
In the end he is stabbed by Centaur's unicorn horn and dies. He was able to see through Gekkou's blindness.

However, he has also shown a deep compassionate and honorable side, like when he attacked a subordinate who tried to shoot Michelle while he was saving Togashi.
- He had an even match against Momo and his Shinki Fuukon, but the burden of his teammates being imprisoned prevented his Shinki Fuukon, turning it into a one sided match. After the ōendan of his classmates reawakens Momo, Gouki suggests they settle things with the Entou Kyouyutou. He is sure of a victory after he breaks Momo's katana, but Momo ties the katana back together with his hachimaki and uses it as a boomerang to attack from behind, dousing Gouki in flames.
- After the flame of Momo's Shinki Fuukon disappears, Hyoei Todo has a sniper shoot him with a tranqulizer bullet. Unaware of this, Gouki overwhelms Momo with his Senretsuken and goes to stab him with his katana, but his katana breaks on the Otokojuku Representative Successorship Proof pendant Jaki had given Momo and instead Momo's fist goes through Gouki's chest. Afterwards Gouki is made aware of Momo's gunshot wound and raises his hand in victory before collapsing.

He refers to his wolves as his brothers. He nearly beats J with his Tougun San Chuushou, but J uses his Jet Sonic Megaton Punch to break the Todo Statue to bury the wolves underneath the rock. He then uses his personal taijutsu to fight and overwhelms J with his Binsakai Shousai, Soukaku Byoukou, and Soukaku Houchuusatsu, but J hits him on the crown of his head with his Flying Crash Megaton Punch, burying him up to his head in the ground. Because he abused their feelings during the fight his "brothers" were about to eat his head, but J had broken all their fangs and subsequently saved Gobalski's life. After the tournament ends he enrolls in Otokojuku and, along with Hakuhou and Pharaoh, acts as the comic relief. He has not cleaned his fundoshi in three years.
