2027 is the lock — not a vague “eventually” and not January 1 as air day
One Punch Man Season 3 Part 2 is officially set for 2027. The December 2025 finale video from Bandai Namco Filmworks stamped the year and teased the Saitama–Garou confrontation. Until a season (Winter/Spring/etc.) prints, keep the countdown on the year, not a fake New Year’s premiere.
Part 1 already finished December 29, 2025 — do not search it as “still airing”
The first cour ran 12 episodes through late December 2025 and stopped mid–Monster Association war. Part 2 is the second half of the same Season 3 label, not a soft Season 4. Mixing “when does Season 3 start” with this page skips that Part 1 already shipped.
How Season 3’s split actually lines up
- Oct 5, 2025 — Season 3 recap special.
- Oct 12–Dec 29, 2025 — Part 1 (12 eps, J.C.Staff).
- Dec 2025 finale drop — Part 2 confirmed for 2027 + Garou teaser.
- 2027 — Part 2 premiere window (month TBA on this page).
The year-long gap is the production story — not a canceled second cour
Part 1’s reception put animation quality under a microscope. Official answer was not cancellation: a 2027 return for Part 2. That gap is intentional calendar space, not permission to invent a Fall 2026 stamp. Wait for J.C.Staff / the hero association site to name the season.
Frequently asked questions
Quick answers about this release date.
1When does One Punch Man Season 3 Part 2 premiere?
Sometime in 2027 — Bandai Namco Filmworks locked the year with the Part 1 finale announcement (Dec 2025). No month or day yet. January 1 on trackers is a year-window placeholder, not a premiere night.
2When did Part 1 air?
October 12 through December 29, 2025 — 12 episodes at J.C.Staff covering the Monster Association cour’s first half. A recap preceded the run on October 5.
3What is Part 2 expected to cover?
The announcement special teases Saitama facing Garou after Part 1 closed the Orochi clash mid-arc. Exact episode count and cour length are not printed — wait for the 2027 season stamp.
4Is this still J.C.Staff?
Yes. Season 3’s pipeline stays at J.C.Staff for the split-cour return. Studio gossip that invents a Madhouse handoff for Part 2 is not an official staff change.
