The Tojo Clan
Voiced by: Satoshi Tokushige
- "It may not seem it, but I'm trying my best to navigate this path I'm on."
The son of Sohei and Yayoi Dojima. Kiryu seeks him out in the second game as someone who can rebuild the Tojo Clan to glory after Terada's death, not realizing he lost himself after his father's murder and served time. When Kiryu finds him, he's pretty much become just another street punk, but he's convinced to aid Kiryu against the Omi clan, and eventually becomes the Sixth Chairman of the Tojo Clan. He's since remained a staunch ally of Kiryu's, but struggles to maintain control the Tojo Clan amid its financial woes and power struggles from within.
- Alliterative Name: Daigo Dojima.
- Authority Equals Asskicking: Just compare Daigo's fighting abilities from his days as a street punk and The Lancer to his run as the sixth Chairman of the Tojo Clan. Even more impressive as his opponent is Kiryu of all people.
- Badass in Distress: He's held captive twice in the second game, is shot in the third and again in the fifth.
- Big Damn Heroes:
- In the third game, when Kiryu and Mine are cornered by Richardson and Black Monday, Daigo recovers from his coma just in time to pull out a gun and take out everyone in the group.
- He does the same thing in the fifth game, coming out of his coma in time to save Majima and Saejima by shooting Kurosawa's gun out of his hand and gunning down all of his men.
- Broken Pedestal: Downplayed but Daigo made it clear in the second game he was disappointed in Kiryu (and the Tojo Clan by extension), going as far to say that Kiryu was his hero. Gradually becomes a Rebuilt Pedestal once Kiryu convinces him to rejoin the Tojo Clan.
- The Cameo: One of Kiryu's substories in Yakuza 0 revolves around Daigo when he was a spoiled school boy, who calls out Kiryu to hang out with him despite being kicked out of the clan and has a large target on his back.
- Childhood Friends: With Tatsuo Shinada, as we learn in Yakuza 5.
- Despair Event Horizon:
- After his father was killed and the Tojo was in shambles, he lost faith in his hero, Kiryu, as well as the Clan that raised him. He made a move in Kansai and was set up, which landed him in prison for five years.
- It happens again in the fourth game due to Tojo Clan running out of money. You don't see it on his face, because he's kinda The Stoic.
- Disguised in Drag: In a sidestory in the non-canon Yakuza: Dead Souls, Majima has poor Daigo dress as a woman to use as bait for luring out zombies, since he said he'd do anything to help him out earlier to prevent more casualties. At the end of it, he orders Majima never to speak of it again.
- The Don: From the third game onward, as the Sixth Chairman of the Tojo Clan.
- Expository Hairstyle Change: In the second game, he has loose and messy hair. From the third game onward, he has his hair slicked back.
- Even the Guys Want Him: Mine falls head over heels with him, though not in a healthy way.
- Face-Heel Revolving Door: In the fourth game, he turns his back on his allies for the sake of saving the clan, selling out Majima to the police and serves as Kiryu's Final Boss, but redeems himself at the end, having pulled Majima out of jail and is present during the inauguration of the Saejima Family.
- Final Boss: For Kiryu in 4.
- The Hedonist: He's introduced as this in Yakuza 2, but it takes a good ass-kicking from Kiryu to get him back into shape.
- Iconic Sequel Character: Following his introduction in the second game, each game since often has him heavily involved with the plot in one way or another. Even in those where he barely appears due to being incapacitated or arrested, he's still the focus of those who wish to overthrow or kill him.
- Informed Attribute: Supposedly has the makings of a great leader according to Kiryu, under his rule the Tojo Clan faces constant disasters where he's usually put in a position of helplessness and it's still up to Kiryu and others to clean up the mess. Acknowledged in 6, where Kiryu states that Daigo was put in a position of power without any real support.
- Kick the Son of a Bitch: While emptying a pistol into and killing Koji Shindo was very shocking (especially when Kiryu actually spares the latter after a usual beat down), the fact that Koji betrayed the Tojo Clan and caused the deaths of Tojo Clan Officers is simply just too much to let him get off that easy. And he was trying to have his way with his mother...
- The Lancer: He serves as one to Kiryu in the second game, a role he shares with Kaoru.
- The Leader: Kiryu picked him to join the Tojo because he was always good at inspiring loyalty and command. Even as a street punk he has a gang that calls him aniki despite him not insisting.
- Leitmotif: A unique one in each game that you fight him. "Hit and Kill" in Yakuza 2, "For Face" in Yakuza 4, and the self-titled "Daigo" in Yakuza 5.
- Like a Son to Me: In 6, Kiryu states that he sees Daigo as a son, though one that he has failed as a father figure for, especially in how he pushed him to become Chairman.
- Like Father, Unlike Son: Other than committing a few questionable actions in later games, it's pretty hard to believe he's the son of Sohei. Especially given light of Sohei's actions in the prequel and flashbacks, not to mention the actions that got Sohei killed to begin with.
- Manipulative Bastard: In the fourth game, he makes a plethora of questionable decisions that cause a huge rift between him and Kiryu, and they only make up after the latter beats some sense into him, literally.
- Properly Paranoid: In 4 and 5, he knew something was shifty about Arai's induction the Shibata family and sent Kido to keep tabs on Arai so he doesn't make things worse. In 5 he was well too aware of how treacherous members of the Tojo used the looming war with the Omi to quietly rise up the ranks and sent not just Majima out as a delegate but certain troublemakers like Aoyama as well to remove them to avoid the same situation in 2 where Shindo uses the ongoing tensions to sell out to the Omi and get a lot of Tojo members killed. He also knew that Kurosawa was going to take advantage of this as well and quietly slipped out of view to go to Nagoya to investigate Kurosawa's former family and their involvement.
- Put on a Bus: He's arrested along with Majima and Saejima in Yakuza 6, thanks to Sugai's machinations. They don't show up again until the ending sequences.
- Reasonable Authority Figure: He wants to do what's best for the Clan, but won't betray his friends to do so. Until the fourth game, that is...
- Recurring Boss: He's fought several times throughout the series.
- Sequential Boss: Along with Hideaki Arai, Takeshi Kido and Seishiro Munakata in the fourth game.
- Spoiled Brat: In Yakuza 0, where he's depicted as a young schoolboy. Although he looked up to Kiryu as a big brother figure even then, Daigo was rather insufferable to be around as he had a nasty temperament, was frivolous with his father's money and used his name when he didn't get what he wanted. But he was also paranoid, convinced that people only wanted to be around him to get in good with his dad and other yakuza. Kiryu only puts up with it for so long before he decides to set him straight, even if it means using his fists, but the threat alone is enough.
- Tattooed Crook: Has a tattoo of Fudō-myōō the fierce, angry guardian of Buddha entity. Perhaps reflects on his abilities of being a natural leader.
- Took a Level in Badass: Takes a couple in the second game the moment Kiryu convinces him to go back to the Tojo Clan.
- Unknown Rival: To Ryuji Goda. Daigo has a very justified reason to dislike Ryuji yet the latter clearly doesn't recall the incident upon their encounter.

- "If you've got a problem with that... try makin' as much as we do!"
Patriarch of the newly created Uematsu family, introduced in Kiwami 2. He's the one who brings the most money in the Tojo Clan, which Terada recognized and promoted him to a direct patriarch. Because of this, is the one closest to the seat of Clan Captain. With a knack for finance and money, Uematsu is the opposite of Kiryu: A yakuza who thinks with his head rather with his fists. Because Majima is also gunning for the seat of Clan Captain, Uematsu is hostile towards him.
- Advertised Extra: He's advertised as one of the key players in Majima's scenario. And while has an important role, he dies early in it.
- Boom, Headshot!: His corpse has a bullet hole in his forehead.
- Frame-Up: His death was used by Ibuchi to implicate Majima.
- Good Scars, Evil Scars: Has a large scar on the right side of his head.
- Smug Snake: Is confidently smug when his earnings far exceed that of the rest of the family. Doesn't take much for Majima to wipe that smugness off his face.
- The Unfought: Despite sending his goons after Majima's family, Majima never gets the chance to fight him at all. He gets killed before the Mad Dog could get to him.
- We Hardly Knew Ye: After appearing in the opening scene, he sends his boys to take care of Majima. The Mad Dog decides to pay him a little visit, and discovers his corpse instead.

- "What is the meaning of this, Majima?"
Patriarch of the newly created Ibuchi family introduced in Kiwami 2 and originally one of Uematsu's men. Having a unique background in consultation, he possesses an overwhelming amount of knowledge has a capacity for making rational judgments. He's the second money bringer of the clan after Uematsu and feels Majima is a threat to his or Uematsu's position as future Clan Captain. He has an open disdain for senior management, who he feels are fixated on old values like moral codes and humanity, preventing the organization from reaching its potential. In truth, he was one of the many catalysts of the Omi/Tojo conflict as he has Ryota kill several members of the Omi Alliance to settle debts of his to start a war. Ultimately he was outed facing prison for his proxy murder. He opts to kill himself instead to kickstart the war.
- Arc Villain: He's the main antagonist of "The Truth of Goro Majima" scenario, as well as the Final Boss.
- Badass Bookworm: Is one of the smartest members of the Uematsu family and can go toe to toe with Majima. Just look at his Dynamic Intro.
- Badass in a Nice Suit: As per usual in the Yakuza series.
- Better to Die than Be Killed: Trying to murder the head of a Clan can get you into big trouble in the Yakuza world. So instead of being on the receiving end of Cold-Blooded Torture, he opts to kill himself instead.
- The Chessmaster: Manipulates both the Tojo Clan and the Omi Alliance so as to start his war.
- Combat Pragmatist: His boss fight against Majima has him fend him off with a pistol.
- Decomposite Character: His character design resembles the original design of Ryo Takashima.
- Four Eyes, Zero Soul: Fitting with the fact that he's the smartest member in the Uematsu family he also wears glasses. And he's also the main antagonist.
- Final Boss: Of Majima's Campaign.
- Hate Sink: An irritatingly smug and utter slimeball who views himself better than others, its satisfying to see Majima put him back in his place.
- "Get Back Here!" Boss: Subverted; in contrast to other gun-wielding bosses who prefer to run away and take potshots while their goons cover them, Ibuchi fights alone, walks towards the player and uses kicks and grab-moves at close-range besides just shooting his gun.
- Large Ham: Well he is voiced by Takehito Koyasu so it's a given, though he's more of a Cold Ham in his introductory scene. He definitely hams it up just before he fights Majima.
- Leitmotif: Update With Gunfire
- The Mole: It's heavily implied that he was working under the orders of one of the Omi captains, though exactly which one is left in the air.
- My Death Is Just the Beginning: Ibuchi intended for Majima to be the sacrificial lion in Sotenbori to start a war between the Tojo and the Omi. Since Majima beat him, he opts to kill himself to provoke the war.
- Never Bring a Gun to a Knife Fight: Uses a pistol while fighting Majima, guess who wins?
- Smug Snake: Looks down on the Tojo Clan's old guard as a bunch of naive and soft fools, and is overly smug about his own plans. Ends up on the receiving end of Majima's blade in return.
- The Starscream: He tells Majima that he was planning to kill Terada as part of his scheme.
Voiced by: Naoto Takeda
- "If anything, I want you become Clan Captain, boss."
A new member of the Majima family introduced in Kiwami 2, and seems to respect his boss a lot. He entered the Majima family one year prior to the events of Majima's story, by literally knocking on their door and asking to join them. A little careless, he's respected by the senior family members because of his sociable personality, and is entrusted with driving and taking care of personal belongings.
- Apologetic Attacker: He isn't exactly happy about fighting Majima.
- Never Bring a Gun to a Knife Fight: Uses a pistol while fighting Majima.
- Trapped by Gambling Debts: He racked up a huge debt from Mahjong, which eventually puts him in the pockets of Ibuchi.

- "You're a Yakuza, not a fuckin' weasel. You should be putting yer ass on the line."
The Lead Detective of the Osaka Organized Crime Division who is famed for her spirit and determination, she's earned the title of 'Yakuza Eater/Huntress' for her work in dealing with the clans. She first appears placing Kiryu under arrest when he's in Osaka, and while she did it under orders to place him under protection, she has her own agenda. She grew up never knowing who her parents were, and believes he's the link to the truth behind her lost past.
The Deuteragonist and Kiryu's Love Interest in Yakuza 2, she returns briefly in the prologue for Yakuza 3 to tell him goodbye as she heads to the United States for special training, putting her relationship with him on hold to see how far her career can take her. Although they agree to find each other when that time has passed, she hasn't been seen in the series (or its spin-off titles) since.
- Action Girl: The definitive one of the series, she can certainly handle herself just as well as any of the men. She even fights alongside Kiryu!
- Adorkable: Has shades of this, most prominently during her date with Kiryu.
- The Alcoholic: Downplayed, but she's often shown drinking beer frequently. Tamiyo Sayama says Saoru would often frequent bars in times of stress.
- Battle Couple: With Kiryu in the second game, and they even have an exclusive HEAT action together! In Kiwami 2, they're given another exclusive Heat action where she performs a scorpion kick on Kiryu's enemy!
- Break the Cutie: The second game is most definitely this to Kaoru once she finds out who her true family members are and what became of them shortly after the reveal.
- But Not Too Foreign: Is half-Korean, half-Japanese.
- Cutscene Incompetence: She's among the few women in the series who can take part in fights, but in the two cutscenes where she's hit, she goes down instantly.
- Defrosting Ice Queen: She and Kiryu don't exactly start off on the best terms, with her being a cop and him a former yakuza. She refuses to thank him for saving her after she's shot, but afterwards she tends to mellow out and acts reasonable and respectable toward him. She soon warms up to him and even invites him on a date, allowing him to see the real her. Granted, having a few beers probably played a large part in that...
- Deuteragonist: Of Yakuza 2.
- Disney Death: She refuses to leave an injured Kiryu behind in 2 when Terada's bomb is about to go off, and chooses to die at his side. Post credits, it was a dud.
- Dude Magnet: Catches the eyes of both Kiryu and Majima.
- Fair Cop: A cop in her mid-twenties who is intelligent and attractive? Fits the trope like a glove.
- Fanservice: A scene in the second game has Kiryu head back to Serena, only to find Kaoru wearing nothing but a Modesty Towel after helping herself to a shower closeby. She even removes the towel right in front of him to put on a robe. He's completely awkward the whole time.
- Foreshadowing: When she discovers the truth about her half-brother in the climax of Yakuza 2 and decides to confront him, Kaoru leaves a tender and heartfelt recording for Kiryu lamenting how the two of them couldn't end up together because of their different paths. It's the very reason they decide to go their separate ways in Yakuza 3.
- Genius Bruiser: Aside from being able to fight at Kiryu's side, she also specializes in programming, which got her hired by the police under the Hi-Tech Crime Unit. Her skills come in handy when she thwarts a hacking attempt on The Florist's network when his men can't keep up.
- Glass Cannon: A main reason behind the aforementioned Cutscene Incompetence. While she's a competent fighter, she's nowhere as durable as Kiryu. She can dish out heavy hits, but she can't take them.
- Kansai Regional Accent: As to be expected from a cop from Osaka.
- The Lancer: Serves as one to Kiryu in Yakuza 2, a role she shares with Daigo.
- Long-Lost Relative: Ryuji Goda's stepsister, as well as Jiro Kawara's daughter.
- Love Interest: For Kyriu, arguably his biggest one as she's the one he interacts the most and only one he actually kisses on screen.
- Morality Pet: To her half-brother Ryuji Goda.
- Odd Couple: With Kiryu, a former yakuza.
- Parental Abandonment: She grew up in the care of a woman who explicitly wasn't her mother, but would never tell her who her mother was.
- Put on a Bus: She left Japan at the start of Yakuza 3 to receive special training in the United States. Aside from completion e-mails in the third game, she's only alluded to briefly in Yakuza 5.
- Reasonable Authority Figure: Although she has Kiryu arrested and placed under her supervision when she first appears, she's not entirely antagonistic toward him. Although she's not completely by-the-book, she still takes her job very seriously and is very proud of it.
- Red Baron: Known as "The Yakuza Eater" in the original game's translation. Kiwami 2 changes it to the "Yakuza Huntress".
- Red Oni, Blue Oni: The blue to Ryuji's red.
- Second Love: To Kiryu, following Yumi's death in the previous game.
- Shameless Fanservice Girl: Doesn't seem to think much about undressing while Kiryu is in the room with her.
- Single Woman Seeks Good Man: It takes a while for her to warm up to Kiryu and tries putting her duties as a cop first, but it's when he rescues her from a group of thugs that she mellows out and invites him on a date, and starts to fall for him after he compliments her and tells her that she has many good qualities that others don't recognize, even herself. The inverse also applies, as Kiryu falls for her because he sees her for who she really is.
- Strong Family Resemblance: Ryuji notes in his final moments that she looks a lot like their late mother.
- Temporary Love Interest: She's Kiryu's love interest in the second game, but in the third game's prologue, they decide to put their relationship on hold as Kiryu takes over the Sunshine Orphanage and she goes to the United States to receive special training. Their relationship hasn't been brought up or explored since.
- Toplessness from the Back: The audience and Kiryu are treated to this when she takes off her Modesty Towel to get dressed.
- Trademark Favorite Food: Beer.
- Tsundere: Type A. She often puts up a tough front due to being a woman on the force, and is often frustrated due to everyone around her keeping secrets from her. However, after a few drinks and being rescued by Kiryu by some thugs, she starts looking at him as a person and not as a yakuza, and he's allowed to see her softer and true side.

- "A cop's gut instinct is more than just some guess."
Or 'Killer Kawara', so named for the amount of suspects who die resisting arrest.

- Badass Grandpa: One of the older characters in the game and still pretty hardcore for a cop.
- Blasting It Out of Their Hands: He shoots the detonator out of Kurahashi's hand when he threatens to blow up the room they're in.
- Cowboy Cop: Even worse considering he's Japanese, yet is more than a little fond of his service revolver.

- Disappeared Dad: He is Kaoru's father, who under a series of events, could not see her.
- Get a Hold of Yourself, Man!: Gives Suyeon Jung a wake-up slap when she attempts to let herself and her son die in the burning building.
- Ink-Suit Actor: He's given this treatment in Kiwami 2, now bearing similarity to his voice actor.
- Knight In Sour Armor: He does have morals, but is generally so bitter about everything that it's easy to mistake them for something else.
- Luke, I Am Your Father: Kurahashi reveals that Kaoru's real parents are none other than Kawara and Suyeon, after the two tried to hide the fact her whole life.
- Papa Wolf: Another reason for his Roaring Rampage of Revenge, as to clean up Kaoru's past and ties with the Jingweon, as Suyeon's dying wish.
- Power of Love: He went a good lengths to help Suyeon Jung, a woman who crossed a nasty Despair Event Horizon into giving her a new life, to the point the two eventually gained a daughter together. That daughter is Kaoru.
- Romancing the Widow: Ends up having a child with the widow of the Jingweon boss after saving her and her son from the burning building.
- Red Baron: Best known as "Killer Kawara", although he previously earned the name "Kawara the Devil".
- Roaring Rampage of Revenge: When you realize why he tends to shoot up illegal aliens who had something to do with Suyeon's murder.
- Taking the Bullet: After being shot repeatedly, he takes one last bullet for Kaoru, and doesn't survive long after that.

- "You only say that 'cause you don't know how scary the Jingweon really are! Women and kids are just more meat to 'em!"
The Division Chief of the Osaka Police Organized Crime Unit and Kaoru Sayama's boss. He used to work in Kamurocho before being transferred to Osaka, and remains in close contact with them. On Sudo's request, he orders Kaoru to place Kiryu under protective custody to keep him from getting killed during the Tojo/Omi peace talks. He was involved with the investigation of the Jingweon Mafia along with Jiro Kawara, and finds himself involved once again when they return after 26 years.
- The Ace: Date mentions at the time he joined the force, Bessho was seen the golden boy of the Kamuro police along with Kawara.
- Cowboy Cop: He's exercised some underhanded methods in the past, has made deals with the yakuza, and used the Dojima Family to wipe out the Jingweon mafia, which resulted in him being transferred down to Osaka. In actuality, he and Kawara used it to move Suyeon to Osaka.
- Da Chief: Bessho serves as this for the Osaka Police Organized Crime Unit. He can be harsh towards Kaoru and isn't bothered by keeping secrets from her, but he does care for her well-being.
- Ink-Suit Actor: He's given this treatment in Kiwami 2, sporting a new actor. Funny enough, his actor resembles how Bessho already looked.
- Jerk with a Heart of Gold: He's rather brash, blunt, and comes off as rude and dismissive, but it's mainly because how hardened he is and recognizes just how truly dangerous the Jingweon mafia is. When Kaoru chews him out and walks out for keeping the truth from her, he kindly asks Kiryu to watch over her.
- Kansai Regional Accent: He's the chief of the Osaka Police Organized Crime Unit. Did you expect otherwise?
- Purple Is Powerful: Wears a purple shirt and isn't someone to take lightly.
- Red Baron: He was known as "Bessho the Viper" back when he worked with Kawara.
- What the Hell, Hero?: Kaoru chews him out when she discovers his involvement with the Jingweon Massacre and never mentioned it to her the whole time. Although he has his reasons, he's rather dismissive of her anger and concerns.

- "You have no idea what I'm capable of!"
The Chief of the Public Security Foreign Affairs Division of the Tokyo Police, who's been investigating the Jingweon Mafia's presence in Tokyo for several months alongside Sudo. Following the bombing on Millennium tower, he informs Date of their presence, and suspects Kazuki is actually one of them.
Late in the game, he takes Date hostage to lure Kiryu, Kaoru and Kawara to the Millenium Tower, revealing he's one of the survivors of the Jingweon Massacre, while taking out The Florist of Sai's network in the process. He reveals to Kaoru the identity of her real father before shooting him repeatedly. After Kiryu beats him, he attempts to shoot Kaoru but her father takes the bullet, and the two proceed to shoot Kurahashi dead before Kawara dies.
- Climax Boss: He's fought before the game reaches its final chapter.
- Evil Sounds Deep: Only in the original game, he's given a very deep voice.

- We Can Rule Together: Kurahashi offers Saoru a chance to join the Jingweon, due to her mother being of Jingweon blood.

- "I dunno what happened, but I do know this! It's the Tojo that made Kaoru's life this hell!"
The proprietress of the bar "Aoi", she's also Kaoru's foster mother. She had worked as a doctor several years before and has known Kawara for many years. She knows much of the truth behind Kaoru's past, including who her parents were, but is determined to keep it a secret from her.
- Kansai Regional Accent: She sports one, being a longtime resident.
- Parental Substitute: They're not blood related, but Tamiyo considers Kaoru to be her daughter all the same.
- Secret Keeper: Although she knew Kaoru's real parents, Tamiyo refuses to tell her who they were, much to her frustration. Suyeon left Kaoru in her care before she was killed, and it was her dying wish for Kaoru never to learn of her past.
- What the Hell, Hero?: Gives one to Kaoru early on. After treating her bullet wound, Kaoru refuses to thank Kiryu for saving her because he's a yakuza, earning this reaction from her.
The Omi Alliance
Voiced by: Masuo Amada
- "If the Omi can be of help along the way, it'd be my pleasure to assist you."
Jin Goda is the fifth chairman of the Omi Alliance and the foster father of Ryuji Goda. At 65 years old, his many years of fighting have left him bound to a wheelchair. Kiryu meets him following Terada's death in hopes to reach a truce between the two clans and avert war. Although the elder Goda accepts, his son Ryuji stages a coup to prevent it from happening and has him kidnapped, leaving his whereabouts unknown throughout most of the game.
- The Atoner: After Ryuji is defeated, Jin offers to turn himself in, saying that Ryuji's actions are also his responsibility as well. Unfortunately, Terada and Takashima's actions prevent him from doing so.
- Badass Beard: Along with just having short of Barbarian Longhair, he looks like he's from a different time period.
- Cultured Badass: The entire Omi HQ building is decorated with several priceless antiques that Goda picked out himself, and his men describe him as a man of culture.
- Distressed Dude: He's kidnapped early on and isn't seen for much of the game. And because he's bound to a wheelchair, there's not much he can do.
- Parental Substitute: He's not Ryuji's actual father, but took him in after Suyeon left him for Kawara. Ryuji doesn't hold much love for him, more so after he learns the truth.
- Reasonable Authority Figure: When the rest of his men are eager to wage war against the Tojo Clan and deem Terada a traitor, Goda instead agrees to the truce offered by Kiryu, and wasn't pleased by Terada's death.
- Red Oni, Blue Oni: The blue to Ryuji's red.
- Retired Badass: Was mentioned to have been a powerful figure before age caught up with him, which left him bound to a wheelchair.

- "Lemme know if ya need incense money for Terada's funeral. I'd be happy to spot ya a billion or two."
The man behind most of the wealth of the Omi Alliance, he's a smug, smirking jerk whose only redeeming attribute is his skill with money.
- Asshole Victim: You won't be feeling sorry for him when he gets what's coming to him.
- Big Bad Wannabe: Sees himself as the prime candidate for chairmanship of the Omi Alliance, and is always harassing Kiryu and the Tojo Clan from behind the scenes. Unfortunately, he's easily at Kiryu's mercy and swiftly taken out by Ryuji.
- Cowardly Boss: You don't fight him directly, but he'll run off all the same.
- Disney Villain Death: Goda kicks him off the highest floor of his castle, after slicing him open with his sword, no less.
- Evil Laugh: Emits one after he has Haruka brought up to his castle, thinking he's discovered Kiryu's Achilles' Heel.
- Foil: He is a lot like Sohei Dojima as the top earning clan leader who uses wealth and dirty tricks to get his way, however unlike Dojima he is less collected and way louder about his smugness.
- Four Eyes, Zero Soul: Golden glasses and a greedy and careless bastard.
- Hate Sink: A Dirty Coward who is loud, rude, arrogant, and always flaunting his wealth, you're gonna want to kick his ass based on his introduction alone. All bets are off when he has Haruka kidnapped to lure Kiryu to his castle. Although Kiryu doesn't get to introduce Sengoku to his fists, what Ryuji does to him is a lot more than Kiryu ever would, and boy does he deserve it.
- The Idiot from Osaka: Serves as this for the Omi Alliance.
- Impaled with Extreme Prejudice: Gets skewered by Ryuji's katana.
- Jerkass: He'll talk down to anyone who's not nearly as rich as he is. Naturally, this means everyone, even his superiors.
- Kansai Regional Accent: Speaks with one, hailing from Osaka.
- Meaningful Name: "Tora", from his first name, means "Tiger". His last name is a reference to the Sengoku Period, a significant point in Japanese history which saw the rise of the ninja, was also seen as the golden age of the samurai, and saw the construction of many castles - all of which Kiryu encounters when he goes after him. The period was also known for its leaders being seen as ineffective and were chronically backstabbed, similar to how Sengoku treats Jin Goda as anything but his superior.
- Mister Big: Similar to Sohei Dojima, he stands out from the other characters by being short and fat.
- Rich Bastard: He's the one raking in the cash for the Omi Alliance, is boastful and doesn't hesitate to remind everyone how filthy rich he is. He has a castle in Osaka that splits in two, revealing another golden castle that rises from the ground, and is filled with traps, samurai and ninjas for Kiryu to fight against. Oh yeah, and tigers.
- Sharp-Dressed Man: Just to show off how rich he is, his suit is colored yellow.
- Sinister Shades: Sports golden ones, as pictured above.
- Smug Snake: The worst, in a game filled with them. He doesn't even have the strength or smarts to try and justify it, just his cash, and he completely pisses himself when he realizes all the toys and men he bought with it are no match for Kiryu's fists.
- Too Dumb to Live: Mouthing off to Ryuji Goda about how he's only successful because of his father - especially after he just carved a bloody gash in your chest with his katana - is a very stupid move.
- The Unfought: He's not fought by Kiryu, but his "beatdown" is just as gratifying.
- Villainous Breakdown: After Kiryu beats his tigers with his bare hands, he's completely petrified of him and runs off with Haruka. It doesn't get better when he finds Ryuji sitting in his chair.
- Would Hurt a Child: He has Haruka kidnapped to lure Kiryu to his castle.
Voiced by: Hiroshi Tachi (Yakuza 2), Hakuryu (Kiwami 2)
- "God, you're all so stupid! Why do you trust people like this? It's ludicrous!"
Ryo Takashima is the chief director of the Omi Alliance and Patriarch of the Takashima Clan. An intelligent individual, he appears to be Jin Goda's right-hand man and a strong candidate as his successor. Friendly and civil at first, following Ryuji's insurrection, his true colors are quickly revealed.
- Adaptational Ugliness: He appears more old and craven in the Kiwami 2 remake as opposed to his rather youthful appearance in the original. Here, he's modelled after his voice actor while his original design is instead reused for Kei Ibuchi.
- Big Bad: He's the true antagonist of the game, allying himself with the Jingweon mafia.
- Bitch in Sheep's Clothing: When he's first introduced, he treats Kiryu as a guest and is just as respectful and reasonable towards him as Jin Goda is. But once the elder Goda is kidnapped early on and the race for the title of Chairman is on, he makes it very clear to Kiryu that he has no one to trust.
- Blasting It Out of Their Hands: Pulls this off against Kaoru in the finale.
- Blood Brothers: Was this with Terada back in the latter's days as one of the Four Kings of Omi, and even teamed up together so as to bring down the Tojo Clan. Unfortunately, Takashima only saw Terada as a means to an end.
- Boom, Headshot!: He's shot multiple times during a shootout with Ryuji, and meets his end this way.
- The Chessmaster: Along with Terada, he's behind mostly everything in the game.
- Chronic Backstabbing Disorder: He betrays the Omi Alliance and kills Jin Goda to take it for himself. He's also in cahoots with the Jingweon Mafia and Kim Daejin, who he also betrays and kills after he's no longer useful in his plans. However, Kim anticipated his betrayal and acted against him as well.
- Dark Is Evil: Wears all black and is not on Kiryu's side.
- Evil Sounds Deep: In the original game, he has a very deep voice that stands out.
- Faux Affably Evil: Acts calm, polite and reasonable in his first scene. Turns out it was all an act.
- Four Eyes, Zero Soul: He wears glasses, and while he treats Kiryu with respect when they first meet, he turns out to be a cruel manipulator.
- Greater-Scope Villain:
- Of Yakuza 2. He's the one to manipulate the Jingweon Mafia's desire for vengeance against the Tojo Clan to suit his own needs.
- He's also implied to be this in the "Truth of Goro Majima" scenario, as Ryuji accuses him of working with Ibuchi, which Takashima denies. Considering they have similar goals in mind, and the fact Ibuchi's design is modelled after Takashima's original character model, it's very likely.
- Ink-Suit Actor: He's given a new appearance in Kiwami 2, now resembling his new voice actor, Hakuryu.
- Man Behind the Man: He's using the goals of Ryuji, Terada and the Jingweon Mafia to accomplish his own.
- Manipulative Bastard: Manipulated the Tojo Clan, the Omi Alliance and the Jingweon Mafia to suit his ends.
- The Mole: He was actually working with Yukio Terada to help him with his revenge for the Korean genocide.
- There's No Kill Like Overkill: Meets his end when Ryuji Goda riddles his body with bullets, before being finished off with a final headshot.
- Smug Snake: An intelligent man who knows he's an intelligent man, but is too arrogant and smug for his own good.
- The Starscream: Betrays the Omi Alliance and starts operating under the schemes of the Jingweon Mafia along with Terada. He also kills Jin Goda to take over the Omi Alliance.
- The Unfought: Kiryu never gets the chance to deal with him. That honor goes to Ryuji instead.
- Villainous Breakdown: He undergoes a brief one when the dying Terada sets off the timer for the bomb, not knowing that the bomb is a dud. He goes into it even more when he's taken by surprise by an awakened Goda who proceeds to gun him down.
- Would Hit a Girl: Near the climax, Takashima takes Kaoru hostage and planned to kill her to keep Kiryu from trying anything. He gets stopped by Goda.
- You Have Outlived Your Usefulness: Shoots down Jin Goda and Yukio Terada so he can subjugate both the Omi Alliance and the Jingweon Mafia in order to spread them across the Asian mainland. However, Ryuji stops that from happening.
- Younger Than They Look: In Kiwami 2. He's still 40 years old, but now shares his actor's likeness, who is in his mid 60's.
- Walking Spoiler: He operates from behind the scenes, with the extent of his true motives revealed in the endgame.
Cabaret Club Grand Prix
- Hot-Blooded: She can get really aggressive toward Kanzaki and Yuki suggests calling her the fire breathing hostess.
- Meaningful Name: Her name can be read as "little Yuki", which, considering that she is Yuki's protege and designated successor, is quite apt.
- Suspiciously Similar Substitute: Looks and acts a lot like Yuki did in Yakuza 0.
- Big Eater: Kana eats even more than Kiryu and gets excited every time they go eat dinner.
- Bit Character: Doesn't get her own character arc or any screentime, unlike the other platinum hostess before being recruited.
- Anti-Villain: She doesn't care for Kanzaki's unethical tactics and participates in the Grand Prix primarily to settle the score with Yuki.
- The Dragon: She is the most successful of Kanzaki's club owners and the final opponent of the Grand Prix storyline.
- From Nobody to Nightmare: in Yakuza 0, Kirara was an utterly forgettable Bronze-grade hostess who mostly collected dust in your roster. In the intervening years she worked her way up to becoming one of Sotenbori's most sought after hostesses, and one of the main antagonists in the Cabaret storyline.
- The Rival: She had a friendly rivalry with Yuki, up until the latter retired from being a hostess.
- Bitch in Sheep's Clothing: He seems like a pretty nice guy at first glance, but he allowed Kanzaki to stack the odds of the Grand Prix in his favor so that Four-Shine wouldn't have a chance in hell against him.
- Dirty Coward: Just after his involvement in Kanzaki's attempts to sabotage Four-Shine has been revealed, he quickly ducks out of the club to avoid facing the wrath of everyone.
- Large Ham Announcer: He's rarely ever seen without a smile on his face, he's always wildly gesticulating and tends to shout quite a bit whenever the player does exceptionally well in the cabaret club minigame. Fittingly, once his crimes are revealed and he's ousted from his position the only one hammy enough to take up the role for the rest of the subplot is Majima himself.
- What Happened to the Mouse?: He's never seen again after being outed as Kanzaki's accomplice. However, during the epilogue of the Cabaret Club Grand Prix storyline, he's said to have been arrested alongside Kanzaki for conspiring with his crimes.
