What happens when one of the most acclaimed anime directors in the industry tackles the brutal history of the Mongol Empire with a deceptively gentle art style? You get Jaadugar: A Witch in Mongolia, and it is shaping up to be the most talked-about anime of summer 2026.
The team behind the series just dropped a massive announcement, revealing the complete additional voice cast, the opening theme song details, and confirming a one-hour premiere event on July 4, 2026. If you thought this anime was going to be just another historical fantasy, think again.
Naoko Yamada Takes on the Mongol Empire
At the helm of this ambitious project is executive director Naoko Yamada, the creative genius behind K-On!, A Silent Voice, Liz and the Blue Bird, and The Heike Story. Known for her emotionally nuanced storytelling and breathtaking visual compositions, Yamada is stepping into entirely new territory with the 13th-century Mongol Empire.
The series follows a protagonist named Sitara, who vows revenge against the Mongol Empire after losing everything she holds dear. But this is not just a tale of vengeance. The story weaves through the complex power dynamics, cultural customs, and political intrigue of one of history’s most formidable empires.
Star-Studded Voice Cast Revealed
The latest announcement brought four major voice actors into the fold, and their roles suggest the series will dive deep into the inner workings of the Mongol royal family.
Ami Koshimizu voices Töregene, a historical figure known for her political influence during the Mongol succession crisis. Koshimizu noted that despite the limited historical records, the emotions and psychological tension in the story come through vividly, with intense verbal sparring scenes that keep viewers on edge.
Hiro Shimono takes on the role of Ögedei, the third son of Genghis Khan and future second Emperor of the Mongol Empire. Shimono described Ögedei as a fun-loving, breezy character with a notorious love for drinking, but hinted that there is much more depth beneath the surface.
Daisuke Namikawa joins as Chagatai, another son of Genghis Khan known for his strict adherence to Mongol law and tradition. Namikawa revealed that the production staff actually traveled to Mongolia to experience the atmosphere firsthand.
Kenji Nojima rounds out the cast as Jochi, the eldest son of Genghis Khan whose disputed paternity remains one of history’s great mysteries. Nojima described the series as presenting a delicate, storybook-like visual world that contrasts sharply with the mercilessly harsh realities of the era.
SEKAI NO OWARI Delivers the Opening Theme
The opening theme song, titled Stella, will be performed by none other than SEKAI NO OWARI, one of Japan’s most beloved bands. The track was written specifically for the anime, with music composed by Nakajin and lyrics penned by frontman Fukase.
Author Tomato Soup shared a touching comment about the song, saying that upon first hearing the completed track, they felt it was written with deep empathy for the story’s protagonists.
World Premiere at Anime Expo 2026
Adding to the excitement, Jaadugar: A Witch in Mongolia has been selected for a world premiere screening at Anime Expo 2026. Episodes 1 and 2 will debut as a one-hour special on July 3 at the convention, followed by the official TV broadcast on July 4 at 11:00 PM JST on TV Asahi.
The anime was also selected for the TV Films category at the Annecy International Animation Film Festival 2026, one of the most prestigious animation events in the world, running from June 21 to 27 in France.
Why This Anime Is Going to Break Through
Several factors make Jaadugar stand out from the crowded summer 2026 anime lineup. First, the creative pedigree of Naoko Yamada alone is enough to draw massive attention. Second, the Mongol Empire setting is virtually untouched in anime, offering a fresh historical backdrop.
The contrast between the gentle art style and the brutal realities of 13th-century warfare creates a unique visual tension that could redefine how historical anime are made. Add in the political intrigue of the Mongol succession, a revenge-driven female protagonist, and a killer opening theme from SEKAI NO OWARI, and you have all the ingredients for a breakout hit.
What Do You Think?
Are you hyped for Jaadugar: A Witch in Mongolia? Naoko Yamada directing a historical Mongol Empire anime with SEKAI NO OWARI on the opening track is a combination nobody saw coming.
