After four years of production, the Bleach anime is finally crossing the finish line. Bleach: Thousand-Year Blood War – The Calamity — the fourth and final cour of the TYBW adaptation — has been confirmed for a 25 July 2026 premiere, and it will adapt the manga’s absolute endgame. This is it: Ichigo vs Yhwach, the conclusion of a 16-year story.
What is Bleach TYBW: The Calamity?
The Calamity (Japanese title: Kashin-tan) is Cour 4 of the Thousand-Year Blood War arc, produced by Pierrot Films under chief director Tomohisa Taguchi and series director Hikaru Murata. It adapts manga chapters 664 through 686, the final chapter of Tite Kubo’s run — covering the last push against Yhwach, the collapse of the three realms after Ichigo is tricked into striking the Soul King, and the climactic battle that ends the series.
Kubo has remained closely involved throughout the anime’s production, reviewing graphics, storyboards and settings. The result has been an adaptation that corrects and expands on some of the original manga’s rushed ending, making The Calamity the most anticipated of the four cours for long-time fans.
When and where to watch in Singapore
The Calamity premieres on TV Tokyo at 11 pm JST on 25 July 2026, which is midnight on 26 July in Singapore. Streaming follows shortly after broadcast.
For Singapore viewers, the most accessible legal option is expected to be Ani-One Asia on YouTube, which streamed previous TYBW cours in over 30 Asian territories including Singapore — though official confirmation for Cour 4 is pending at time of writing. Disney+ has handled international distribution for earlier parts as well; check both platforms from 25 July. In the US, the show is exclusive to Hulu.
If you have not caught up yet, all three previous TYBW cours are currently available on streaming platforms — now is a good time to get through them before the finale arrives.
The Calamity’s new theme songs
Tite Kubo personally selected both theme artists from demo submissions, which is on-brand for an arc that has treated its music as seriously as its animation.
- Opening: “I-BULL” by jo0ji
- Ending: “Rasen” (Spiral) by 9Lana — Kubo praised the track for its “very strong” melody, lyrics and arrangement, as reported by Anime News Network; the song releases digitally on 25 July
US theatrical screenings — and what they tell us about The Calamity’s ambition
Before the TV broadcast, Fathom Events and VIZ Media ran limited US theatrical screenings on 25–29 June 2026 showing the first three episodes in both subtitled and English-dubbed versions, with a bonus behind-the-scenes conversation between Kubo, Taguchi and Murata. The theatrical run sold out quickly in several markets, which speaks to the appetite for this final arc even among audiences who follow the show purely on streaming.
For Singapore fans, the main event is still 25 July on streaming — but the theatrical response suggests Pierrot has delivered something worth the long wait. Keep an eye on the official Anime News Network coverage for streaming confirmation closer to the date.
