In the film series, Soichiro, portrayed by Takeshi Kaga, survives - discovering that Light is Kira and holding him as he dies - but chooses to hide the knowledge from his family. However, in the live-action drama, Soichiro is portrayed by Yutaka Matsushige, which differs greatly from his other counterparts. Although his strong sense of justice and love for his family remain much the same, he is a widower, and Light feels some resentment towards him for choosing to interrogate murderer Kurou Otoharada over going to his wife's bedside when she passed, as well as his repeated absence in his son's life following that event. Yet despite this strain, the pair are much closer than other versions, and their relationship has a huge impact on the story, with Light killing Otoharada and ultimately becoming Kira in order to protect his father. It is this closeness that causes Soichiro to notice changes in Light's behavior, and - is a huge departure from the source material - leads him to suspect his son when L suggests the possibility. This ultimately leads to a confrontation between the two towards the end of the series, in which Soichiro, blaming himself and having instructed his colleagues to assume Light's guilt if he should die, writes his own name in the Death Note before trying to burn it as his final act. In the musical, Soichiro is portrayed by Takeshi Kaga, who also portrayed Soichiro in the live-action film series, effectively making Kaga reprising his role as Soichiro.
