According to a scene from Yakuza: Dead Souls, Goro Majima has a pollen allergy. During an earlier scene, Majima is bitten by a zombie, and despite the zombie's teeth not being able to penetrate his jacket, he thought he was infected. In a later scene where Majima emerges from a destroyed sauna and figures out he was never bitten, a soldier points out a symptom of getting bitten being his eye turning red, only for Majima to sneeze and complain about "pollen season". Since Yakuza: Dead Souls is considered non-canon, Majima's allergy may be non-canonical as well.
