When did Kaiju No. 8 Season 2 air? Production I.G ran July 19–September 27, 2025 (11 episodes) — TBA trackers are stale; Narumi's Week at Work is a separate Fall 2026 short.
Current target date: Saturday, July 19, 2025 (Season 2 premiere (aired)). We update this page when studios or publishers move the window.
Kaiju No. 8 Season 2 already aired: July 19 to September 27, 2025, 11 episodes at Production I.G (Khara on kaiju designs). Hoshina's Day Off ran July 5. Narumi's Week at Work (Fall 2026) is not Season 2 or Season 3.
Season 2 premiere (aired)
Saturday, July 19, 2025
Season 2 already finished — Summer 2025, not a blank TBA clock
If you are still waiting on a “Kaiju No. 8 Season 2” premiere stamp, the calendar is wrong. Season 2 launched July 19, 2025 and closed September 27, 2025 after 11 episodes at Production I.G. Kafka’s second cour already shipped.
Blank “not announced” pages are tracker rot — the window locked and aired
Official channels stamped the July 19 TV Tokyo slot months ahead, with OneRepublic returning for the ending theme “Beautiful Colors.” Catalogs that never updated past TBA are leftover scrapes from the wait after Season 1 (Spring 2024). Honest status: aired, finished, rewatchable.
How Kaiju No. 8’s TV map actually lined up

- Fall 2026 — Narumi’s Week at Work short (separate URL).
- Mainline Season 3 — not dated on this countdown.

Season 2 kept the same-night worldwide X stream — unusual for a Jump hit
Alongside Crunchyroll, the committee pushed real-time worldwide streams on X as the TV Tokyo night aired — the same playbook Season 1 used. That dual pipe is why “when does it drop for me” answers collapsed to one Saturday night instead of a region-lagged Monday dump.
The experimental distribution is already history with the September 27 finale. Move any “Season 2 TBA” reminder off this slug so search stops rewarding a phantom premiere while Narumi’s Fall 2026 short steals the next dated headline.
Frequently asked questions
Quick answers about this release date.
1When did Kaiju No. 8 Season 2 air?
July 19 through September 27, 2025 — 11 episodes on TV Tokyo and affiliates at 11:00 p.m. JST, produced by Production I.G with Studio Khara on kaiju designs. Crunchyroll and same-night X streams carried it outside the Japanese broadcast.
2Is Season 2 still upcoming?
No. The Summer 2025 cour finished on September 27, 2025. If a tracker still shows “not announced,” it is stale SEO — the Defense Force already got its second cour.
3What was Hoshina’s Day Off?
An original side-story TV episode that aired July 5, 2025 — two weeks before Season 2’s premiere — focused on Soshiro Hoshina. It is not Episode 1 of Season 2 and not a replacement for the main cour.
4Is Narumi’s Week at Work Season 3?
No. Kaiju No. 8: Narumi’s Week at Work is a Fall 2026 Gen Narumi short on its own page. Do not merge that October window into a fake Season 2 re-run or an undated Season 3 stamp here.
