Eren Yeager needed more than someone who could shout convincingly. For director Tetsuro Araki, choosing Yuki Kaji came down to a particular contrast: an essentially decent person with something more unrestrained beneath the surface.
Araki discussed that casting decision at an October 23 stage appearance in Japan, more than 13 years after Attack on Titan made its anime debut. According to ComicBook Anime, citing coverage from Oricon, he felt that combination made Kaji a natural match for Eren.
The interesting part is that Kaji did not initially expect to land the lead character.
Kaji thought the role might be Armin
Reflecting on the audition process, Kaji said he had felt positive about how it went. What surprised him was discovering that he had been selected to play Eren rather than Armin.
That makes this a revealing bit of casting history: the actor’s own expectations and the director’s reading of him were not necessarily aligned. Araki had identified qualities he wanted in Eren, even while Kaji was imagining another possible outcome.
Kaji went on to remain in the role through the anime’s studio transition. WIT Studio produced the first three seasons, while MAPPA handled the final season, retaining the established voice cast.
For a production that changed substantially behind the scenes, the actors provided a continuing connection between its earlier and later chapters.
Why the discussion is happening now
The comments accompanied the Japanese theatrical return of Attack on Titan: Crimson Bow and Arrow. Originally released in 2014, the compilation film revisits material from the anime’s first season.
ComicBook Anime reports that its October 23, 2026 return included its first Screen X screenings, with upgraded animation and sound compared with the versions available on streaming platforms.
The release described in the source is for Japan. It does not provide a Malaysian or wider Southeast Asian cinema announcement, so this should not be read as confirmation of a local screening.
The occasion nevertheless brought the conversation back to the beginning of the adaptation—and to the decision that established Eren’s voice long before the final season.
Our take: a useful reason to revisit the performance
For readers in Malaysia and SEA, the value here is less about a cinema release to plan around and more about getting a specific insight into how a major anime performance was chosen.
Our analysis: Araki’s explanation suggests he was looking beyond vocal intensity. His account puts the emphasis on a contrast he perceived in Kaji, rather than simply whether the actor sounded forceful enough for the protagonist.
That is an interesting lens for a rewatch. Instead of listening only for Eren’s biggest outbursts, consider how the performance balances conviction with instability. This is an interpretation of Araki’s remarks, not an additional production detail confirmed by the report.
There is also something refreshing about the modest scale of the revelation. No new season is being announced here. It is a behind-the-scenes explanation of why one actor was chosen—and how that choice differed from what the actor himself had anticipated.
