Sohei Dojima (堂島 宗兵, Dōjima Sōhei)
Sohei rose to power during the rise of the Tojo clan, as a skilled businessman and criminal he has successfully controlled most of Kamurocho through his three enforcers. In 1980, due to the string of Dojima Family yakuza members being killed by the Jingweon Mafia, he ordered his two lieutenants, Kazama Shintaro and Futoshi Shimano, to eliminate all members of the mainland mafia. This led to the infamous Jingweon massacre, to which only 3 Jingweon survived and made the Dojima Family a major force within the Tojo Clan. It was said that Sohei has had many affairs with other women, with his wife Yayoi knowing but still remaining faithful. Despite that, she sent her son Daigo away to Kinecho without any connection to the Tojo clan in hopes of keeping him from walking the same path as his father.
Yakuza 0 Edit
As one of the three powerhouses in the Tojo clan, Dojima had the most power in terms of manpower and influence, compared to Kazama's good relations with the head Chairman and Shimano's secret alliance with the Omi. When word broke out that there was a land ownership dispute involving the small plot of land that will be the site of the Millenium Tower, he instructs Kiryu to assassinate the target in which he refuses. Sending Daisaku Kuze, one of his trusted men to kill Kiryu, he fails before him and was forced to perform an yubitsume in front of the boss. Angered, he send his men to Soutenboori to find the holder of the will but fails to thanks to the efforts of Kiryu and Majima. Ultimately Makoto, the recipient of the will appears and offers him the land in exchange for the lives of the men who killed her brother where he states it was a mere formality to prevent anyone from leeching off his fortune. He shoots Makoto to show how expendable she is but ultimately fails to acquire the land as she had already entrusted it to Majima who gives it to Masaru Sera. In his first act as the upcoming chairman, he orders the surviving lieutenants to be taken to Anagura indefinitely for their actions as Dojima loses his hopes of being the next Chairman of the Tojo.
Dojima's Family was widely respected with Kazama as his lieutenant and members like Kazuma and Nishiki to carry out his wishes. His wild, violent temper made him a fearsome leader and no one ever dared to challenge him, until one night. Dojima had his eye on Yumi and one night he took her away to his office against her will. As soon as the word got to Nishiki, he arrived in a fury and killed his Oyabun without thinking. Nishiki and Yumi were reeling in shock as Kazuma burst in just ahead of the police. Kazuma had only seconds to make a life-altering decision and based on brotherhood and honor, so he took the rap for killing Dojima.
Sohei Dojima is a Japanese man of average height(in 0 he is shown to be shorter than Kuze, Awano, and Shibusawa), with a modest build. His black/grey hair is cut very short, with there being no stray hair pieces and none of it is out of place. In 0, he is either depicted wearing a tan colored kimono or a very expensive looking Western suit. In the original Yakuza, he is only shown when Kiryu arrives to find him dead, where he is wearing a white suit with a red inner dress shirt and tie. In the flashback during Yakuza 2, he is shown to be much younger, having a slightly larger build, his hair has more colored and is a little longer, and he is sporting a slight beard. The one constant throughout all the games are his aviator sunglasses, which he is always depicted wearing them no matter where he is(even when he is indoors).
He is first mentioned in Yakuza 1 by Nishiki who, when Kiryu says that his application for his own family hadn't been accepted by Patriarch Dojima, sarcastically tells him that there's no way he would object because Kazama-san had his weight behind it, due to Kazama-san being the only one keeping the Dojima family afloat. Nishiki then continues that all Dojima does is "..somethin' else these days. All he does is yak about the glory days". A little further on in the story, it is said that Dojima was morally corrupt, having a violent temper, cheating on his wife frequently(it was said that he had a mistress on every corner), and was overall unpleasant. During th flashback in Yakuza 2 when dicussing the extermination of the Jingweon, he is understanding of Kazama's objections to the attack and considers his proposal to instead drive them out. But he also concurs with Shimano, deciding that they had gone too far, saying "Kazama, I hear where you're coming from. (Shimano yells in a shocked tone "Boss!") "Cool it a minute. Still...these Jingweon guys are different. Their methods are inhuman. If we let this keep up, the Dojima Family's gonna be in danger."
