Yoshitaka Mine is the main antagonist of the video game Yakuza 3. He is the former captain of the Nishikiyama Family, the chairman of the Hakuho Clan, and one of the lieutenants of the Tojo Clan. He is also the interim chairman of the Tojo Clan in the absence of both Daigo Dojima and Osamu Kashiwagi. As the main source of the Tojo Clan's income, he is known as the "Treasurer of the Tojo"


Mine's cold personality comes from the hardships he experienced in his early life, further worsened by a breakdown over Daigo's apparent death. He is not afraid to harm those standing in his way. Yet, he is willing to attempt change, accepting Kiryu's words to him after their fight. He seems to have no tolerance to people who speak negatively Daigo Dojima, stabbing one of his own subordinates with a table knife for doing so.

Fighting Style

Despite looking like a businessman, Mine is a very strong fighter. He possesses a tremendous amount of strength, as proven when his few punches easily cripple Kanda in spite of him being a resilient powerhouse fighter. He was also one of the few people to contend with Kiryu, and was strong enough to leave the Dragon of Dojima breathless and heavily bruised despite losing to him in the end.


Mine was born in 1976 to unnamed parents and orphaned at a very young age. He grew up in poverty, raised in an orphanage by his adoptive father who became terminally ill when Mine was still a child. On his deathbed, his father advised him to make something of his high intelligence and was sorry to leave him on his own. Having spent his childhood rejected by his peers for his background, Mine worked tirelessly to achieve wealth and status.

He became a very successful businessman in adulthood, earning a fortune in insider trading and real estate. Before the age of thirty-one he founded a venture company where he was employed in the capacity of both the company's chairman and the manager of the R&D department. As he had spent most of his life in solitude, it comforted him to have subordinates he could consider friends. He felt he was at a place in life where he could find what he truly wanted: genuine bonds with others.

Mine's acquired lifestyle led him to be surrounded by people who used him for their own gain, resulting in numerous betrayals throughout his life. In 2007, motivated by immediate profit, his trusted colleagues staged what in Mine's view was a coup d'etat in which he was dismissed from his position as the manager of the R&D department. To Mine, this left him as the company's chairman only in name.

The same night, he witnessed an assassination attempt on Daigo Dojima that left four Tojo men dead. Contrasted with what had just happened to him, the incident had a lasting impression on Mine. He became obsessed with finding out what Daigo's subordinates saw in him that they would die to protect.

With his investigation at a standstill, he decided he needed to see what caliber of man Daigo was for himself. He bribed Tsuyoshi Kanda to introduce him to the Nishikiyama Family under the guise of wanting to expand his business.

Mine used aggressive methods to acquire property for the Nishikiyama Family, poaching third-tier families from under other Tojo organizations to get at their territory. The family's profits skyrocketed as a result. Their success caused conflict with the second acting patriarch of the Nishikiyama Family, which ended in Mine and Kanda driving him out. Though Kanda claimed credit for Mine's work and became the third patriarch, Mine shot up the ranks as his right-hand man.

As Mine had hoped, their success did not escape Daigo's notice, who was aware Mine was the one working behind the scenes. He warned him his methods went against the moral code of the yakuza and would end up getting him killed. Mine considered Daigo naïve and disregarded his advice, certain he would change his tune if enough money was put in front of him. Not satisfied that he understood enough about Daigo just yet, he continued his ways.

While transporting seven hundred million in payments to HQ, Mine and Kanda were ambushed by the second acting patriarch along with men from several families Mine had poached. Outnumbered, Kanda abandoned Mine and drove off with the money, a betrayal that left Mine in a near-suicidal state of despair. Daigo intervened, offering the second acting patriarch one billion yen in exchange for Mine's life and even taking a bullet for him. When asked why he would risk his life for someone like him, Daigo told Mine that it was natural to him, as he considered every member of the Tojo Clan his family.

This ultimately lead Mine to realize that the yakuza was exactly what he had been searching for, a society in which the bonds between men ruled supreme. For the first time in ages, Mine had found someone he loved and respected, and he came to consider his bond with Daigo his reason to live. With Daigo's support and his own clear thinking and financial prowess, he soon became the chairman of the Hakuho Clan as well as lieutenant advisor to the Tojo Clan.

Yakuza 3

Mine meets Kiryu for the first time in Purgatory, having come to apologize for Kanda's actions the previous night, as that it was him who funded the Nishikiyama Family to allow them to stage a coup against the other families. Looking to resolve the matter, he shows Kanda's decapitated head.

A flashback in Mine's office reveals, Kanda is angry over his defeat by Kiryu, destroying antiques in Mine's office. While Mine calmly tells him to refrain from destroying any more expensive antiques, as he doesn't comprehend their value, Kanda lunges at Mine in animosity, To Kanda's shock, Mine effortlessly counters him. After further consecutive blows, Kanda helplessly falls to the floor, pleading mercy, while Mine explains to him how he has outlived his usefulness and orders his subordinates to execute him away from his office.

Back in the present, Mine addresses that, thus, he hopes to consider the matter is closed and that there is nothing to worry about in regard to Goh Hamazaki, either, since the Snake Flower Triad's defeat will have forced him into hiding. Kiryu expresses his disapproval over Mine's actions, asking if this is what Daigo would have wanted. Mine responds to Kiryu how his reluctance to give up the orphanage caused Daigo to be shot and that his idealism is nothing more than hypocrisy. Assuring Kiryu and his allies that he will continue on for the sake of the Tojo Clan, he leaves.

While Kiryu and Date meet with the Minister of Defense Ryuzo Tamiya and learn that Tamiya's former secretary, Toma, approached Mine to help acquire land for the resort deal, Mine travels to Downtown Ryukyu, Okinawa by plane. With the employ of the Tamashiro Family he destroys Sunshine Orphanage to further the resort development project. Mine orders the family to stall Kiryu in Okinawa while he travels back to Tokyo to find Daigo at Toto Hospital. During the plane journey, his subordinates discuss how Mine becoming the Seventh Chairman is something worth celebrating. Mine overhears their conversation and stabs one of the men's hand with a dinner knife for insulting Daigo.

At Toto Hospital, he sits beside Daigo when he receives a phone call from Andre Richardson. Mine assures him, in English, that everything is going according to schedule and that there will be no changes in the plan with Kiryu is about to arrive.

Kiryu meets Mine, along with Daigo brought up there on a stretcher, on the hospital roof. When Kiryu accuses him of having plotted to murder Daigo in order to become the Tojo Clan's Seventh Chairman, Mine reveals to him that he is an orphan just like him, as well his true (albeit misguided) motives behind his actions. Unable to cope with Daigo being in a coma after being shot, he sought power to fill that loss. To fulfill that ambition, he has two obstacles: first, to compassionately kill Daigo in his vegetative state and second, to kill the person whom Daigo thought of the most highly, Kiryu. Kiryu points out the futility in Mine's actions, and that his isolation was a result of his self-centredness, prompting Mine to shoot at him out of rage. To get through to Mine, Kiryu challenges him to a duel to prove him wrong, which Mine accepts gladly and mentions how he won't be easily beaten. After a gruelling fight, Mine is defeated.

After Mine's defeat, he lies down on the rooftop, exhausted. He receives an urgent phone call from his secretary, whom he thought he mattered to. When it turns out she called to discuss a business deal, Mine laments how it all goes back to money, yet everyone desires bonds of friendship and love is in all of us, before cutting off the call. Mine asks Kiryu whether his clear state of mind means that his life has ended, who responds that as long as one is still alive, they can start anew. He helps Mine up, shortly before the CIA agents appear.

However, Mine confirms that they are not CIA and that it was just a cover for the Black Monday organization. Richardson points out how Mine's and Kiryu's roles have come to end. Before Richardson executes them both, Daigo suddenly recovers from his coma and shoots him and his men. While seemingly safe, Kiryu rushes to Daigo and Mine falls back to his knees over Daigo awakening, Richardson gets back up and attempts to shoot Daigo. Mine charges him instead, Richardson shoots at him, but Mine forces him to the edge of the roof. Standing there, Richardson struggling in his hold, Mine shares his regrets for his actions, confesses that he is not worthy to be beside Daigo and that he wishes he had met Kiryu sooner. While Daigo and Kiryu shout for him to stop, Mine throws himself along with his former collaborator Richardson off the roof, killing both of them.
