to portray people living with leprosy, "said to be an incurable disease caused by bad karma", after visiting the Tama Zenshoen Sanatorium near his home in Tokyo. Lady Eboshi is driven by her compassion for the disabled, and believes that blood from the Great Forest Spirit could allow her to "cure [her] poor lepers". Michelle Jarman, Assistant Professor of Disability Studies at the University of Wyoming, and Eunjung Kim, Assistant Professor of Gender and Women's Studies at the University of Wisconsin–Madison, said the disabled and gendered sexual bodies were partially used as a transition from the feudal era to a hegemony that "embraces modern social systems, such as industrialization, gendered division of labor, institutionalization of people with diseases, and militarization of men and women." They likened Lady Eboshi to a monarch.

Minnie Driver, the English voice actress for Lady Eboshi, commented similarly: "It's one of the most remarkable things about the film: Miyazaki gives a complete argument for both sides of the battle between technological achievement and our spiritual roots in the forest. He shows that good and evil,
