“What If …” is not a question reserved for Marvel Comics; rather, it’s a question that’s been asked by philosophers, scientists, and more for the bulk of humanity’s existence. Within that question lives innumerable possibilities that no amount of planning can prepare you for — unless you’re Batman. Thus, when Warner Bros. Animation teamed with Kamikaze Douga to create 2018’s extraordinary Batman Ninja, fans buckled up for an absolute ride as the world of characters that began with Bill Finger and Bob Kane traversed time and space to end up in feudal Japan in a marvelous elseworld story. Now, seven years later, audiences are invited back to the world of Batman Ninja as the Bat Family discovers that what they thought had been left in the past is alive and well in the present. Mixing traditional Japanese imagery with modern animation techniques run through a DC Comics filter, Batman Ninja vs. Yakuza League carries on the wild and exciting adventure that compliments what came before while demonstrating an enormous understanding of the source material.
The Bat Family, comprised of Batman/Bruce Wayne (voiced by Koichi Yamadera), Robin/Damien Wayne (voiced by Yuki Kaji), Nightwing/Dick Grayson (voiced by Daisuke Ono), Red Robin/Tim Drake (voiced by Kengo Kawanishi), Red Hood/Jason Todd (voiced by Akira Ishida), and Alfred (voiced by Hochu Otsuka), had returned from their adventure in feudal Japan having halted Gorilla Grodd’s (voiced by Takehito Koyasu) Quake Engine which had sent them all to the past and having stopped Joker’s (voiced by Wataru Takagi) plot to rule as Lord Joker. The morning after their return, not only is Damien’s hair back to normal, but yakuza foot soldiers appear to be raining from the sky. A side-effect of their journey across time-space, the Bat Family can see a fissure in the sky where another world appears to be trying to infiltrate and take over Gotham. Heading in to investigate, they learn that Batman’s colleagues in the Justice League have been transformed and now operate under a different set of rules with all but Wonder Woman taking part in the invasion. Can the Bat Family once more save Gotham and prevent terrible destruction or will this so-called Yakuza League prove indomitable?
What follows is based on the 4K UHD physical edition of Yakuza League, provided by WB Discovery Home Entertainment. The film’s been available to screen digitally since March, so we’ll begin with exploring the film itself before digging into the on-disc presentation and bonus.
On the whole, Yakuza League is surprisingly accessible, regardless of whether you’ve seen Batman Ninja. After a brief opening setting up the situation, the credit sequence succinctly recaps the events of Batman Ninja, enabling audiences to have just enough information to understand what’s going to occur next, at least in terms of style and sensibility. Additionally, the character interactions and the general essence is anchored in their DC Comics counterparts, empowering those less familiar with Japanese storytelling (yakuza cinema, Edo era tales, animation styles, and the like) to at least be able to understand character functionality and relationships. For instance, one doesn’t need to know why Wonder Woman, called Daiana, stands apart from Aquaman, called Asha, but, given their history in the comics of serving as representatives of their people who have clashed in various elseworld tales, we don’t require much explanation as to why the two teammates in a different life would stand in opposition. Likewise, the script by Batman Ninja writer Kazuki Nakashima (Promare) beautifully captures the familial tone of the Bat Family, conveying the generally light tone Dick, Tim, and Jason bring to offset the perpetual seriousness of their “father.” One great moment is Dick taking the time to explain the inaccurate meteorological description of the yakuza storm to Jason despite a potentially menacing figure wearing a cloak and traveler’s hat approaching them; the Robins (past and present) are historically snarky and smartasses, something which this film never forgets and peppers throughout with excellent timing. Of the tangential Justice League members, the members of the Bat Family are regarded as among the smartest and most tactically savvy, which Nakashima works into each character conflict as the Bat Family tries to investigate and stop the invasion, making several fight sequences utilize clever solutions to overpowered problems.
While Yakuza League doesn’t reach the heights of, say, Batman Ninja’s tokusatsu elements, it’s no less impressive with the incorporation of other Japanese culture influences and homages. As explained in “Bringing Justice to Japan,” there are little details like the courtesan dress-inspired outfit that makes up Zeshika’s (Jessica Cruz Green Lantern) primary costume, the fish-monger motif for Ahsa, or straight-up borrowing from Lady Snowblood (1973) to create Daiana’s umbrella shield. Those familiar with Japanese yakuza cinema (Big Time Gambling Boss (1968); Yakuza Graveyard (1976); Branded to Kill (1967); Battle Without Honor & Humanity (1974)) will certainly take away more from Yakuza League in the same way that those more familiar with Edo era-based tales (Seven Samurai (1954); 13 Assassins (2021); A Samurai in Time (2024)) did with Batman Ninja; however, the film remains incredibly accessible thanks to the interpretations of the DC characters. Most impressively, Nakashima demonstrates not only one of the clearest understandings of how Batman operates, but how Batman thinks in regard to his teammates, whether Bat Family or Justice League. There’s a brief speech by Batman that literally put tears in my eyes with the accuracy of interpretation that wasn’t even connected to the exploration of ninkyo code that courses through the film proper. While many presume that yakuza is a criminal organization without honor, there is a belief in a code of honor (ninkyo) that seeks to protect others, or, at the very least, reduce harm. The failure to uphold the yakuza code is a critical point of narrative conflict in the 1958 crime thriller Underworld Beauty as the yakuza boss undermines a recently paroled member’s attempts to rectify past mistakes, and the code is similarly utilized here by the way that the main villain of Yakuza League balks at organizational loyalty compared to Daiana who embodies ninkyo, thereby honoring who Wonder Woman is while she serves as an immediate ally for the Bat Family in this strange new world. Again, if you’re aware of the cultural context from which Yakuza League is borrowing, the film is a rich, cinematic ride, but you don’t have to be immersed in the details in order to enjoy yourself.
Though Yakuza League is an inherently Japanese story, be advised that the physical edition defaults to English and must be changed in both the language and audio settings to get the original Japanese with English-language subtitles.
Too few releases have demonstrated that they truly required a 4K UHD edition. From a technical perspective, while their bitrates were above standard HD quality (max 40 Mbps), a film presenting with a bitrate in the low 50s doesn’t make for a good 4K UHD. Impressively, the 4K UHD physical edition moves from the mid-80 Mbps to mid-90 Mbps, making for one of the best 4K UHD presentations in quite a while. It certainly helps that the film is animated, which already allows for the film to be exported more easily in native 4K UHD (much in the same way a restoration from a film negative can, but a digital restoration may not), but there’re also only two brief featurettes included on the disc, so there’s not much else taking up important digital real estate in spite of the film. Though there’s not much to speak of regarding the audio elements (very rarely did the film seem to utilize the rear speakers, thus not immersing in sound), the animation continues to dazzle in its imaginative designs. The 4K UHD aids this by providing greater visual detail so that the audience can discern the various pieces of Batman’s suit (where pieces are grey versus black versus navy versus glowing bluish-white) or notice the intricate details of the tattoos that adorn the Yakuza League members. Most importantly, where the animation is tight and detailed, the increased dynamic range of color and visual detail means that we can also better appreciate the shifts in character design from a more calm, collected presentation (represented by the sharp lines and colors) to a more agitated state (represented by more fluid, dynamic lines that evoke artistic styles of films like Akira (1988) or Paprika (2006)).
If the character design, world-building, and homages are interesting to you, then you’re going to enjoy the two brief featurettes included in both the physical and digital editions of the film. The first, the aforementioned “Bringing Justice to Japan,” is Character Designer Takashi Okazaki (Psycho-Pass 3: First Inspector) literally running down the character designs and reference points for each Yakuza League member. At just over seven minutes, he breaks down many of the new characters, laying out the specific choices made for each and their points of origin. In the second featurette, “Anime Action: Choreographing the Fights,” you hear from multiple crew members on aspects of scripting, fight design, and more amid finished sequences and storyboards. I do not recommend watching either of these before watching the film proper in order to preserve as much of the experience as possible as both are highly informative.
With the upcoming cinematic kick-off of the new DC Studios universe with 2025’s James Gunn-directed Superman, it would be easy to discount something like Yakuza League. I encourage you, if you have any love for DC Animation, to seek this one out, not just because it’s a fantastic follow-up to Batman Ninja, but also because it’s a solid outing all on its own, replete with numerous jokes for DC Comics fans anchored in Japanese references. The best part is that it doesn’t try to replicate elements of the first film which dazzled, like the tokusatsu robot fights. Instead, it leans into the characters themselves to generate intelligent interactions, narratively propulsive action scenes, and jokes that enhance moments without detracting from the seriousness of the situation. If we’re truly lucky, we’ll get another outstanding adventure in another seven years, and I hope they keep these coming. The Batman Ninja films are among the best Warner Bros. Animation has offered out of their DC Animated line in some time, not just for their innovative animation, but for the way they demonstrate a deep knowledge and love of the characters.
Side Note: A new 4K UHD edition of Batman Ninja is expected to release on May 20th, 2025. No word yet on if a two-film physical collection will be available, but both can be purchased digitally in a package.
