Yoshihara is a minor antagonist featured in Yakuza 0.
After Makoto Makimura turns herself over to Keiji Shibusawa so she can negotiate with Patriarch Sohei Dojima, Shibusawa sends a group of hitmen to the place where she and Goro Majima had agreed to meet.
This group of thugs, led by Yoshihara, confronts Majima on a rooftop overlooking the Empty Lot in central Kamurocho. After telling him of Makimura's meeting with Dojima, the group attack Majima but are quickly defeated by him. After a further beating, Yoshihara reveals to Majima that Makimura is meeting Patriarch Dojima at his penthouse atop the Sebastian Building in Roppongi.
Later on, when the Shibusawa Family are raiding the Nikkyo Consortium's base in the Tokyo Docks to assassinate Makimura and Masaru Sera, Yoshihara is amongst the Shibusawa men who participate in the attack.
