Batman Ninja vs. Yakuza League (ニンジャバットマン対ヤクザリーグ, Ninja Batman vs. Yakuza League) is an upcoming anime superhero film directed by Junpei Mizusaki and Shinji Takagi, written by Kazuki Nakashima, produced by Warner Bros., and animated by Kamikaze Douga and YamatoWorks, based on the DC Comics character Batman.

Only a day after returning from the past, Batman and his allies discover that the world isn't quite the same as they left it.

The entire island of Japan no longer exists and neither do the heroes of the Justice League.

In late May 2024, it was announced that the sequel to Batman Ninja was in development, with Junpei Mizusaki returning to direct and Kazuki Nakashima writing the screenplay, with Koichi Yamadera reprising his role as Bruce Wayne / Batman.
