The Story Behind Jaadugar: A Witch in Mongolia
Jaadugar: A Witch in Mongolia, known in Japan as Tenmaku no Jādūgaru, is based on Tomato Soup’s historical manga, which has been serialized on Akita Shoten’s Souffle platform since 2021. The anime brings the acclaimed manga to life with a story inspired by real historical events.
The series follows Sitara, a young girl sold into slavery in 13th-century Persia. After being captured during a Mongol invasion, she takes the name Fatima and begins a journey that eventually puts her on a path to challenge the empire that changed her life.
Animation studio Science SARU is producing the series, with Naoko Yamada serving as chief director and Abel Góngora directing. Character designer Kenichi Yoshida also created the anime’s key visual, showcasing the sweeping landscapes of the Mongolian Empire and the story’s two main characters.
Opening and Ending Themes Bring Top Artists Together
While SEKAI NO OWARI performs the opening theme “Stella,” the ending theme, “STAR,” is performed by QUEEN BEE. The pairing brings together two of Japan’s best-known music acts for one of this season’s biggest anime releases.
The anime premiered on July 4 with a one-hour special featuring its first two episodes. It aired on TV Asahi’s IMAnimation programming block and BS Asahi, introducing viewers to the historical fantasy series with an extended debut.
The voice cast includes Kenji Nojima, Ami Koshimizu, Hiro Shimono, and Daisuke Namikawa. Even before its television premiere, the production earned international attention after being selected for the Annecy International Animation Film Festival 2026, while the original manga won the Grand Prize in the Comic Division at the 55th Japan Cartoonists Association Awards.
