Batman Ninja vs. Yakuza League (ニンジャバットマン対ヤクザリーグ) is a 2025 animated superhero film directed by Junpei Mizusaki and Shinji Takagi, based on the DC Comics character Batman. It is the sequel to Batman Ninja (2018) and features Batman and his allies fighting to protect Gotham City from an invasion of yakuza-style criminals led by an alternate version of the Justice League.
Plot
A day after returning from the past, Batman and his allies discover that the world is not the same as they left it. Japan no longer exists and neither do the heroes of the Justice League. Also, yakuza are raining from the skies. The yakuza belong to Hinomoto, a Japan from a parallel universe, and are using an interdimensional rift above Gotham City to invade Earth. On Earth, only the people who previously time-traveled can see the rift.
Batman and Robin use the rift to travel to Hinomoto, while Nightwing, Red Hood, and Red Robin stay behind to capture the remaining yakuza. The Bat family are soon ambushed by the Yakuza League, a corrupt counterpart of the missing Justice League and the leading group of the Hagane yakuza clan who took over Hinomoto.
