Warner Bros. Discovery is expanding its content reach in Japan through a strategic partnership with Amazon Prime Video and Hulu Japan, launching HBO Max as an integrated hub within both platforms on October 1st. Rather than operating as a standalone app, the service will provide Japanese subscribers access to the full Warner Bros. Discovery library, significantly broadening what was previously available through individual licensing agreements.

The launch accompanies new original programming exclusive to the region, including a fresh Harry Potter series debuting at Christmas. This partnership approach with local streaming services reflects WBD's strategy to maximise distribution in key international markets whilst leveraging established platforms to reach existing subscriber bases.
