Kyoto Animation has a unique way of making any historical period feel intimate. Sparks of Tomorrow brings that to the summer of 1907, in the Meiji era, with a fifteen-year-old girl caught between arranged marriages and a boy who passionately talks about the future of electricity. The new anime trailer confirmed the premiere for July 5, 2026 on Netflix worldwide, along with a new visual and five additional cast members.

The trailer expands the look at the story of Inako Momokawa and Kihachi Sakamoto, reinforcing the tone of a series built around the tension between family expectations and the desire to decide one’s own destiny. The opening “Eureka Evrika” is performed by Luna Goami, while the ending “Soarin'” is by Ginger Root.

About Sparks of Tomorrow

Sparks of Tomorrow (20 Seiki Denki Mokuroku) is a novel by Hiro Yuki with illustrations by Kazumi Ikeda that received an honorable mention in the Kyoto Animation Awards in May 2017, being the only work recognized that year. The KA Esuma Bunko imprint of Kyoto Animation published it in August 2018, and the anime adaptation was announced the same year. The story takes place in the summer of 1907, in the Fushimi district of Kyoto. Inako, the second daughter of a sake brewer, feels that nothing she does goes right and lives under the shadow of her father’s expectations. Her life changes when she meets Kihachi at the Fushimi Inari Shrine, a young man who rejects gods and speaks enthusiastically about electricity as humanity’s future. When the topic of an arranged marriage arises at home, Inako finds in Kihachi someone who helps her find her own voice, and together they embark on a search across Kyoto and Shiga Prefecture for a rare book that could change everything.

Does the historical setting in the Meiji era seem like a strong enough differentiator for Sparks of Tomorrow to stand out among summer premieres, or does the youth romance element make it too similar to other series in the genre?
