Sazae was a very liberated woman, and a lot of the early plot lines revolved around Sazae bossing around her husband, to the amazement of her neighbors, who believed that a man should be the head of his household rather than the wife. Sazae later became a feminist who was involved in many comical situations, regarding her association with her local women’s group.
