Kyoto Animation's first original TV series since the studio's tragic 2019 fire is finally airing, and it is already splitting critics between "gorgeous" and "frustrating." Sparks of Tomorrow premiered on July 5, 2026, and this steampunk romance about a boy chasing a lost catalog of electrical inventions has turned into one of Netflix's most talked about anime experiments of the year. If you have been searching for exactly when new episodes land, how many are left, or whether some other platform is secretly streaming it too (spoiler: no), you are in the right place. Below, I am breaking down the release schedule, the precise Sunday drop time across time zones, the full voice cast, and what critics and fans are actually saying about it eight weeks in.

Sparks of Tomorrow imagines an alternate early 20th century Japan where technology developed around steam power instead of electricity, leaving Kyoto permanently shrouded in smoke and soot. The story follows Kihachi Sakamoto (voiced by Yuma Uchida), a once hopeful boy who grew distrustful of the future after his older brother Seiroku disappeared during a war expedition, taking their shared "20th Century Electrical Catalog" with him. Years later, a chance meeting with Inako Momokawa (voiced by Sora Amamiya), the devout second daughter of a Fushimi sake brewer who is quietly grieving her late mother, pulls Kihachi back toward the dream of an "Age of Electricity" he had tried to abandon.

Set in the summer of 1907, the 40th year of the Meiji era, the series is animated by Kyoto Animation and based on Hiro Yūki's 2018 light novel 20 Seiki Denki Mokuroku (20th Century Electricity Catalog), directed by Minoru Ōta.¹ What most tracker articles skip is the timeline behind that release: the anime adaptation was first announced back in 2018, then the studio's Kyoto facility was destroyed in the July 2019 arson attack that killed 36 staff members. Watching Sparks of Tomorrow finally reach Netflix eight years after its announcement carries a quiet weight for longtime KyoAni followers, this project outlived the very building it was conceived in.

Sparks of Tomorrow Release Date and Episode Schedule

Sparks of Tomorrow is confirmed for 13 episodes, releasing weekly rather than as a full season dump.² The series began July 5, 2026, and has held its Sunday cadence without a break week so far:

What Time Does Sparks of Tomorrow Come Out?

Netflix releases Sparks of Tomorrow the same day as its Japanese broadcast, at 23:00 Japan Standard Time, rather than staggering the international rollout.³ Because JST does not shift for daylight saving, the local drop time in most other regions stays consistent week to week:

A handful of tracker sites round this up to "early Sunday morning" for US viewers, which is close enough for casual watching, but if you want to catch it the moment it lands, set your alarm for the exact time above rather than a rough estimate.

Where to Watch Sparks of Tomorrow

Netflix is the only legal way to watch Sparks of Tomorrow outside of its original Japanese TV broadcast on Tokyo MX, BS11, ABC TV, and TV Aichi.⁴ There is no Crunchyroll simulcast, no HIDIVE release, and no delayed international window, Netflix licensed the show for exclusive worldwide streaming and drops it globally the same day it airs in Japan. A Netflix subscription starts at roughly $8.99 a month in the US on the ad supported plan, though exact pricing and available tiers vary by country.⁵

Cast, Staff, and Theme Songs

Minoru Ōta directs, with series composition from Tatsuhiko Urahata and music by Hitomi Kotō, all under Kyoto Animation.¹ The starring cast includes Yuma Uchida as Kihachi Sakamoto, Sora Amamiya as Inako Momokawa, and Koki Uchiyama, Daisuke Ono, Shunsuke Takeuchi, Minako Kotobuki, You Taichi, Natsumi Kawaida, Kazuki Ura, and Daisuke Hirakawa rounding out the supporting roles.⁶

The opening theme, "Eureka Evrika," is performed by rising vocalist Luna Goami, who also wrote the lyrics, while indie pop artist Ginger Root handles the ending theme, "Soarin'." Both musicians are working on their first anime theme song project. Goami described landing the role in personal terms: "Sometimes reality surpasses our dreams."⁷

My First Impressions Watching Sparks of Tomorrow

I put off starting this one for a few weeks because "steampunk romance from KyoAni" sounded like it might be style over substance, and I have been burned by pretty looking premieres before. I was wrong to wait. The opening episode's hand painted backgrounds genuinely stopped me mid scroll on my second monitor, the kind of frame you want to pause and study rather than skim past while folding laundry. What surprised me more is how much it reminded me of hunting through old electronics catalogs at flea markets for my home theater setup, that same mix of nostalgia and half realized ambition runs through Kihachi's obsession with his brother's catalog. It is not a fast show, and if you go in expecting Attack on Titan pacing you will bounce off it in the first ten minutes.

How Are Critics and Fans Reacting?

Reception so far is split roughly along the line I expected. On the visuals, there is near universal agreement, critic Randy Myers of Decider called it "an ambitious series that works its magic in its first scene," giving it an 80 out of 100 score.⁸ Rotten Tomatoes' aggregated critic consensus leans positive too, praising the animation's shift between styles.⁹ Anime News Network's episode by episode review has been the most skeptical voice, arguing the first few episodes lean on stock character traits more than the visuals can carry, though the reviewer stopped short of writing the show off entirely.¹⁰

Fans discussing the show online keep reaching for the same comparisons, so here is how it actually stacks up against two of them:

If Violet Evergarden's pacing worked for you, Sparks of Tomorrow will likely feel familiar. If you came in hoping for Baccano!'s chaotic ensemble energy, this is a much slower, two person character study by comparison.

Is Sparks of Tomorrow Getting a Season 2?

With nine episodes down and four to go, it is too early for a renewal decision either way. Netflix and Kyoto Animation typically wait to see how a season lands with viewers before greenlighting more, and the source light novel's remaining material would need to be confirmed before any continuation is planned.

The Bottom Line on Sparks of Tomorrow

Sparks of Tomorrow is not trying to be a binge watch. It is a weekly appointment, dropping every Sunday at 23:00 JST exclusively on Netflix, with four episodes left before its September 27 finale. Whether you land on the "gorgeous but slow" side or the "gorgeous and worth it" side of the fan debate, the schedule and streaming details above should be all you need to catch up before episode 10.
