Sparks of Tomorrow is airing weekly on Netflix and Japanese broadcasters, with nine episodes released. The series has received mixed reviews, with critics praising its animation and themes but criticizing characterization and specific episode choices.
Sparks of Tomorrow, Kyoto Animation's first new television series since the 2019 arson attack, premiered on July 5, 2026, on Netflix worldwide and on Tokyo MX, BS11, ABC TV, and TV Aichi in Japan. The series adapts Hiro Yuki's novel, which won an honorable mention at the 8th Kyoto Animation Awards in 2017 and was published under the KA Esuma Bunko label in 2018. Director Minoru Ota, making his directorial debut, leads a production that includes series composer Tatsuhiko Urahata, character designer Kohei Okamura, and music composer Hitomi Koto. The cast includes Yuma Uchida as Kihachi Sakamoto, Sora Amamiya as Inako Momokawa, Koki Uchiyama as Yosuke Mizoe, and Daisuke Ono as Seiroku Sakamoto.
The series follows an alternate-history Meiji-era Kyoto where steam power dominates, centering on the young inventor Kihachi and Inako, a girl searching for a book called the Electrical Catalog. Opening theme "Eureka Evrika" by Luna Goami released on July 6, with Ginger Root's ending theme "Soarin'" following on July 13. At Anime NYC, Ginger Root and producer Mao Takayama detailed the show's deliberate aesthetic system: episode six uses gekiga-style animation, color palettes shift from muted browns in Kyoto to blue in Shiga, and oil-painting backgrounds were built digitally for consistency.
Critical reception has been divided. Reviews praised the animation but found early episodes unfocused and characters undefined. Episode six earned the strongest assessment for its thematically complete exploration of technology and art, while episode four was criticized for depicting a deception-based resolution to grief as healing. Episode seven drew a 3.5 rating for an unbelievable escape plot, and episode nine drew sharp criticism for pairing a gay character with a child-predator role, a combination the reviewer called homophobic.

When a claim about Sparks Of Tomorrow was confirmed, debunked, or disputed against open-web sources. The record stays even after a claim drops off the facts list.
Anime News Network's review of Sparks of Tomorrow episode 10 gives the episode a community score of 3.1. The reviewer criticizes it for hammering its communication theme twice, for confirming a romance between Noriko and Seiroku that was never developed, and for spending the rest of its runtime reuniting Kengo and Noriko instead of letting the characters talk. The review argues the show keeps robbing itself of tension.
The ANN review of episode 9 of Sparks of Tomorrow criticizes the episode for confirming that Yosuke, a schoolmate of the late inventor Seiroku, was romantically in love with him, while also casting Yosuke as a man trying to marry a child. The reviewer calls the combination homophobic, and argues the episode's conflict could be resolved by a single conversation. The review also notes the episode lacks prior animation flair.
At Anime NYC, musician Ginger Root and producer Mao Takayama showed a preview of episode eight of Sparks of Tomorrow and explained the series' artistic choices. Episode six uses gekiga-style animation for a training montage, Kyoto backgrounds are muted and brown while Shiga introduces blue, furniture placement tracks the seasons through machiya customs, and the oil-painting backgrounds were built digitally for consistency.
Episode 8 of Sparks of Tomorrow reveals why Kengo Kuga supports Kihachi despite his alignment with Yosuke Mizoe: he carries survivor's guilt over Seiroku's death in the Russo-Japanese War. Seiroku died in a bayonet charge while Kengo survived because a catalogue half in his pocket stopped a bullet. The episode also shows Kihachi and Inako restoring power to the electric door guarding the rest of the catalogue, though it includes a palm scanner that did not exist in the early 20th century setting. Jonathon Ha's English dub performance as Kengo is singled out as effective.
Anime News Network rates Sparks of Tomorrow episode 7 at 3.5. The review finds the escape plot, where Inako's sister substitutes for her at a betrothal ceremony despite being much taller, hard to believe. Kengo Kuga's sudden decision to help Sasaki and Inako feels unmotivated, since his character was poorly defined until now.
Anime News Network's review of Sparks of Tomorrow episode 6 gives the show its strongest assessment yet, praising a thematically complete installment that explores technological and artistic innovation. The episode features Kihachi inventing electric instruments, a battle-of-the-bands at an amusement park, and a rock performance that overcomes Inako's anxiety. Persistent flaws in character depth and plot coherence remain.
Episode 5 of Sparks of Tomorrow opens with a college student spying on teenagers, then follows him as he uses an electrical love tester invented by Kihachi to learn whether Suzu Harashima returns his feelings. Suzu rejects the public confession. The review criticizes the episode for spending its runtime on that subplot and on nobleman Yosuke Mizoe while the Kate-Suzu romance goes unacknowledged, and calls the science-fantasy conceit a growing problem.
Anime News Network's review of Sparks of Tomorrow episode 4 calls the show's handling of grief and the invention of the telephone "borderline harmful." The episode frames the cast tricking a grieving widow into believing she is speaking with her dead husband via a rudimentary telephone as a positive outcome, which the review argues is exploitative and undermines genuine community-based healing.
At Anime Expo 2026, Kyoto Animation director Minoru Ota and producer Satori Senami gave interviews about their new series Sparks of Tomorrow. Ota described his informal mentorship at the studio, while Senami explained the producer's role in forming committees and budgets. The show premiered July 5 after a long silence since its 2018 announcement.
A review of the first three episodes of Sparks of Tomorrow on Anime News Network criticizes the show's steampunk Meiji setting and weak characterization despite stunning animation from Kyoto Animation. The reviewer finds the script frustrating and the large cast of gimmicky characters unengaging, comparing the show unfavorably to ensemble works like Baccano! and Durarara!! The show streams on Netflix.
The Anime Feminist review of Sparks of Tomorrow's first episode praises its fluid, imaginative animation and experimental style but finds the premiere a tonal hodgepodge. The episode introduces a steampunk world where young tinkerer Kihachi seeks to bring electricity to a steam-dominated society, but the narrative juggles many characters and plot points without cohesion. The villain feels out of place, and the female lead's role is unclear. The review notes the show is from Kyoto Animation.
Kyoto Animation's Sparks of Tomorrow, a project shelved after the 2019 arson attack, premieres on Netflix July 5. The first two episodes screened at Anime Expo 2026, followed by a Q&A with director Minoru Ota and producer Satori Senami. The series, set in an alternate-history Meiji-era Kyoto, follows a clumsy girl and an inventor as they navigate a steampunk world on the cusp of an electric age.

Kyoto Animation's upcoming television anime Sparks of Tomorrow will feature opening and ending theme songs by Luna Goami and Ginger Root, respectively, with both tracks set for global digital release in July 2026. The opening theme "Eureka Evrika," performed by Luna Goami, will be released on July 6, one day after the series premiere on July 5. The ending theme "Soarin'," by Ginger Root, will follow on July 13. The series is set in an alternate-history early 20th-century Kyoto where steam power dominates, following a boy fascinated by electricity and a girl carrying her late mother's memory. "Eureka Evrika" was composed by Hitomi Koto, who also handles the series' soundtrack, with lyrics written by Goami. Goami stated she was pregnant during production, which she said added emotional depth to the song's themes of life and rebirth. Ginger Root, the solo project of Cameron Lew, wrote, composed, and arranged "Soarin'" entirely himself. Lew described the project as a dream opportunity as a longtime anime fan.
