Short answers, pulled from the story.
Seitarō Kitayama was an early Japanese animation director whose films from 1917 include the first examples of commercial production of anime. Researcher Yoshirō Irie of Japan's National Film Center described him as one of the fathers of anime.
Kitayama released at least ten animated films in 1917, including Battle of a Monkey and a Crab, Hanasaka-jiji, Bunbuku chagama, Shitakire suzume, Kachikachiyama, Neko to nezumi, Itazura posuto, Chokin no susume, Yume no jidōsha, and Chiri mo tsumoreba yama to naru.
Kitayama drew repeatedly from Japanese folktales and legends. His films include adaptations of Hanasaka-jiji, Bunbuku chagama, Shitakire suzume, Kachikachiyama, Urashima Tarō, Momotarō, and Battle of a Monkey and a Crab, all of which are traditional Japanese stories.
Yoshirō Irie, a researcher at Japan's National Film Center, referred to Kitayama as one of the fathers of anime.
Kitayama's work represents the first examples of commercial production of anime, meaning he produced animated films intended for distribution to paying audiences rather than as private experiments.
After his prolific 1917 output, Kitayama produced Urashima Tarō in 1918, followed by Momotarō and Tarou no Banpei Senkoutei no Maki. All continue his pattern of adapting Japanese folklore into animation.
