Bleach: Thousand-Year Blood War part 4, subtitled The Calamity, has been airing since 25 July 2026. AniList lists the cour at 10 episodes, with PIERROT FILMS producing. This is the block that carries Tite Kubo’s Thousand-Year Blood War arc towards its conclusion.
This page was checked and rebuilt on 29 September 2026. The previous version was accurate about the arc but carried a mislabelled key visual and no verified episode count, so both have been fixed.

How the four parts fit together
The adaptation has been released in cours separated by long gaps rather than as continuous seasons, which is why people count it in parts. Adding the four together gives 50 episodes listed so far across four years, and The Calamity is the shortest block of the four at ten.
Where to watch
Disney platforms have carried the Thousand-Year Blood War cours internationally, with availability varying by territory. Check your local listing rather than assuming, because this series has had one of the more fragmented international rollouts of any recent shonen adaptation.
What comes after
The Thousand-Year Blood War arc is the final arc of the original manga. Nothing beyond this adaptation has been announced, so treat any claim of a further season as speculation until a production says otherwise.

Updated 29 September 2026. Start date, episode counts and studio checked against AniList.
Updated 25 October 2026: the series ends tomorrow night. The official site lists episode 50, the last of The Calamity, on the TV Tokyo network at 24:00 on Monday 26 October, which is midnight going into Tuesday 27 October in Japan. BS TV Tokyo follows at 24:30 on the Tuesday. The last two episodes moved off the usual Saturday 23:00 slot, so 49 and 50 both air on Mondays.
This is the end of the whole adaptation, not just the cour. The key visual calls The Calamity the final cour, the site describes Thousand-Year Blood War as the series’ final arc, and the news page is running conclusion events: a BLEACH FES., a listening party for the historic openings and endings, and a pre-broadcast marathon of the whole cour.
