Spoilers for Chainsaw Man Part 1.
When MAPPA’s Chainsaw Man anime aired in late 2022, the Western reception was strong. The production quality was visible, the voice performances landed, and the series introduced Chainsaw Man to an enormous new audience that had never read the manga.
In Japan, the reaction was more complicated.
What Japanese readers noticed first
The critique that circulated most persistently in Japanese online communities wasn’t about animation quality, which was generally acknowledged as impressive. It was about the music.
MAPPA’s adaptation used background music extensively — scoring scenes that, in the manga, relied on silence and negative space. Japanese readers who knew the source material found this disorienting. The manga’s particular power comes partly from Fujimoto’s use of empty panels and wordless sequences — moments where nothing is explained and nothing is scored, and the reader sits in the gap. The anime filled those gaps.
One observation from Japanese anime and manga communities that circulated widely: “原作の間がなくなってる” — the manga’s “ma” is gone. 間 (ma) refers to the productive use of negative space, silence, pause — a quality that Japanese aesthetics have named and valued for centuries. The anime, in filling the silence, removed something Japanese readers had been reading into the space.
The cinematic problem nobody named correctly
Fujimoto is one of the most overtly cinematic manga artists working right now. His panel layouts borrow from montage editing. His action sequences use shot-reverse-shot logic. He referenced a climactic OVA battle sequence when designing the Gun Devil’s debut — structured for maximum visceral impact, not maximum clarity. The manga moves like film.
But “cinematic” doesn’t mean what director Nakayama Ryu seemed to think it meant.
Nakayama went on record stating he wanted to make something that didn’t feel like a typical anime — something closer to live-action Japanese film. Slow. Quiet. Restrained. Japanese anonymous boards put it plainly: the director’s vision and the source material were “壊滅的に合っていない” — catastrophically incompatible.
Fujimoto’s cinematic sensibility is not the cinema of contemplative Japanese auteur films. It’s genre cinema — violent, unpredictable, with tonal lurches that shouldn’t work but do. His own self-description for Chainsaw Man was “邪悪なフリクリ” — an evil FLCL. That’s not a reference point that calls for restrained, documentary-style composition.
The anime chose the wrong cinema.
What happened to the ケレン味
ケレン味 doesn’t translate cleanly. Roughly: the pleasure of theatrical excess, the quality of a performance or image that is deliberately, knowingly over the top in a way that works. It’s the sensibility that makes a villain’s entrance electric, that makes a fight scene feel like a boast.
The manga has it in abundance.
There’s a moment in the Hell arc where the Darkness Devil appears. A door in a sky full of doors. Black liquid falling. Then something genuinely wrong with the visual grammar of the page. Japanese fan wikis describe the appearance as “芸術的” — artistic. What they mean is that it doesn’t look like a power-scaling reveal. It looks like something from a different kind of nightmare. Fujimoto draws it like a director who knows exactly when to cut.
The anime’s version is technically accomplished. What it doesn’t have is that wrongness. The scene is rendered rather than composed.
Japanese anonymous boards identified the same problem across nearly the whole series — “夢バトル以外微妙なんが残念,” everything except the dream battle is a disappointment. The dream battle worked because its logic was already surreal enough that restraint read as disorientation rather than absence of energy. The rest of the series didn’t have that excuse.
And there’s something structural underneath this. Fujimoto’s action works because he draws the before and the after. The gap between them is where the impact lives — the reader’s brain completes the movement, and that completion is part of the hit. When animation fills that gap with actual motion, it can flatten the effect unless the animation brings something the static image couldn’t. Too often in the TV series, it didn’t.
The smoothness was the problem. “アニメは綺麗すぎる” — the anime is too pretty. Fujimoto’s manga is not pretty, and that’s load-bearing. The roughness keeps the reader’s eye unsettled. The adaptation removed the roughness and called it quality.
The ending theme problem
Each episode had a different ending theme — twelve songs by twelve artists. In the West, this was widely praised as a creative gesture, a celebration of the series.
In Japan, the reaction was more divided. The rotating endings were seen by some as a symptom of the same problem as the music: the anime was producing content around Chainsaw Man rather than serving it. A marketing strategy dressed as an artistic choice.
The Reze film changed something
The 2025 theatrical release — directed by Yoshihara Tatsuya, not Nakayama — landed very differently. Japanese reviews pointed to something specific: the action finally had ケレン味. Slow-motion used with intention. Camera placement that composed rather than documented. A cast directed to perform rather than understate. Denji felt like Denji.
Japanese anime and manga communities generally read this as confirmation. The problem with the TV series wasn’t the source material, wasn’t MAPPA’s technical capacity, wasn’t the budget. It was the specific vision imposed on it. Different choices, different result.
Why the gap exists
Western viewers encountering Chainsaw Man for the first time through the anime had no baseline for comparison. They experienced it on its own terms — and on its own terms, it’s a genuinely impressive production.
Japanese readers who came to the anime already knowing the manga were measuring it against something specific. Against Fujimoto’s 間. Against the ケレン味 the manga deployed with precision and the anime mostly lost. Against the roughness that was supposed to make everything feel unstable.
The gap isn’t about quality. It’s about what each version was built to deliver.
The Reze film suggests the distance can close. It took three years and a new director to get there.
