Kyoto Animation's original series Sparks of Tomorrow unveiled a broadcast trailer and five new cast additions ahead of its July 5 worldwide Netflix premiere.
Kyoto Animation's upcoming original series Sparks of Tomorrow revealed a broadcast trailer and five additional cast members on June 14, building momentum toward the anime's July 5 worldwide premiere on Netflix.
The latest announcement adds four voice actors across five character roles to the series. Hiroshi Yanaka joins the cast as Jinemon Momokawa, the father of protagonist Inako, while Mayumi Asano voices her mother, Naeko Momokawa. Daichi Endo takes on the role of Bunshichi Yagura, the father of supporting character Yajiro and uncle to male lead Kihachi. Rounding out the new additions, Ayahi Takagaki pulls double duty voicing both Tome, a maid for the Momokawa family, and Inari, an ermine companion.
These newcomers join previously announced leads Yuma Uchida as Kihachi Sakamoto and Sora Amamiya as Inako Momokawa, fleshing out the family dynamics at the heart of the story.
The newly released broadcast trailer expands on the world first glimpsed in the October 2025 teaser, offering a deeper look at the series' Meiji-era setting and the relationship between its two protagonists. Set in summer 1907, the story follows fifteen-year-old Inako, a sake brewer's daughter in Kyoto. When her father arranges her marriage, Inako and a young man named Kihachi embark on a journey across Kyoto and Shiga prefectures to find the "20th Century Electrical Catalog" a childhood book about electricity that holds the key to preventing the union. The narrative unfolds in an alternate history where steam power still dominates, and the dream of an electrical age represents both personal freedom and societal transformation.
Sparks of Tomorrow marks the directorial debut of Minoru Ota at Kyoto Animation. Tatsuhiko Urahata handles series composition, Kohei Okamura serves as character designer and chief animation director, and Hitomi Koto composes the music. Takaaki Suzuki is credited with worldview setting, reflecting the series' detailed alternate-history backdrop. The opening theme, "Eureka Evrika," is performed by Luna Goami, while Ginger Root contributes the ending theme "Soarin'." A new key visual was also released alongside the trailer.
The anime begins airing on Japanese television on July 5, with a Sunday late-night slot at 11:00 p.m. on Tokyo MX and staggered broadcasts at 11:30 p.m. on BS11, ABC TV, and TV Aichi. Netflix will stream the series worldwide starting the same day. Before the broadcast premiere, a world premiere tour will make stops in Japan, the United Kingdom, Thailand, and North America, with the U.S. debut scheduled for Anime Expo on July 3.
With its Meiji-era setting, original story, and Kyoto Animation's signature production quality, Sparks of Tomorrow is shaping up as one of the marquee original anime premieres of summer 2026.
