One-Punch Man Season 3's second cour will air in January 2027 in Japan. The official announcement, dated October 11, 2026, also introduces a key visual and the first promotional video for the returning installment.
What the January 2027 window confirms
The announcement identifies the second cour of Season 3, not a fourth season. A cour is a block of episodes within a release plan; a new block does not automatically change the season number. Our guide to cours and split cours explains the terminology.
January is a broadcast month, not an exact premiere date. The release does not provide a start day or an episode count for this cour. There is not yet enough information in this announcement to build a reliable episode-by-episode calendar.
Watch the first second-cour promotional video
The official page links the first second-cour PV. It confirms JAM Project as the opening-theme performer and gives the song's title as Never Done～最強VS最恐～. The Japanese subtitle is retained as announced rather than replaced with an unverified English title.
Is international streaming confirmed?
The announcement cited here does not name an international streaming platform for this cour. A service carrying earlier episodes in one country is not, by itself, confirmation that it will carry this installment there or elsewhere. Our explainer on regional anime availability covers that distinction.
What viewers should look for next
Before planning a weekly watch time, look for an announcement that names this second cour, gives an exact start date and identifies your territory. A platform listing for earlier Season 3 episodes does not answer all three questions. For now, January 2027 is the confirmed Japanese window, not a complete international release calendar.
