The Wonderful Wizard of Oz, known in Japan as Ozu no Mahōtsukai (オズの魔法使い), is a Japanese anime television series adaptation based on four of the original early 20th century Oz books by L. Frank Baum. In Japan, the series aired on TV Tokyo from 1986 to 1987. It consists of 52 episodes, which explain other parts of the Oz stories, including the events that happened after Dorothy returned home.

Dorothy Gale is a fictional character created by American author L. Frank Baum as the protagonist in many of his Oz novels. She first appears in Baum's classic 1900 children's novel The Wonderful Wizard of Oz and reappears in most of its sequels. In addition, she is the main character in various adaptations, notably the 1939 film adaptation of the novel, The Wizard of Oz.
