Season 2 premiere
Sunday, October 4, 2026
October 4, 2026 at 4:30 p.m. JST is the locked Blue Box return
Ao no Hako Season 2 premieres Sunday, October 4, 2026 on TBS’s afternoon anime footprint. That is a real clock time, not a vague Fall window — useful if you are syncing a Netflix alarm to the Japan broadcast rather than guessing “early October.”
New studio and director — same romance-and-gymnasium DNA
Electric Circus and Daisuke Sakō replace Telecom Animation Film and Yūichirō Yano. Art direction and editing also flip. Script supervision and other returning credits are why staff pitch continuity of Taiki/Chinatsu tone even while the production line changes.

Netflix owned Season 1’s global weeklies — Season 2 keeps that door, not a Crunchyroll default
A lot of Jump sports titles default to Crunchyroll simulcasts. Blue Box’s first run was a Netflix weekly story worldwide. Season 2’s October Netflix listing continues that pattern — set your watchlist on the right app before hunting late-night sports-anime grids.
Frequently asked questions
Quick answers about this release date.
1When does Blue Box Season 2 premiere?
Sunday, October 4, 2026 at 4:30 p.m. JST on TBS and affiliated stations. Netflix is listed to carry the season in October as well — exact global drop timing may trail the Japan night by hours or days.
2Did the studio change for Season 2?
Yes. Electric Circus takes over animation from Telecom Animation Film. Daisuke Sakō directs in place of Yūichirō Yano, with new art-director and editor credits; series composition and several core roles return from Season 1.
3Is Blue Box the same show as Blue Lock?
No. Blue Box (Ao no Hako) is Kōji Miura’s badminton/basketball sports-romance about Taiki and Chinatsu. Blue Lock is a separate ego-striker soccer manga. Shared “Blue” branding in English search is a coincidence.
4Was Season 1 only one cour?
No. Season 1 ran two consecutive cours from October 2024 into early 2025 on the TBS net with Netflix weekly drops. Season 2 is the next numbered season after that long first run.
