Spoilers for Baki-Dou (刃牙道).
The Musashi most Japanese people carry in their heads is not the historical one. It’s a character — a carefully constructed fictional archetype — that’s been running on repeat in Japanese culture for nearly ninety years.
Itagaki’s version refuses to play along. For Japanese readers, that refusal landed like a gut punch.
How the saint got made
Yoshikawa Eiji’s serialized novel Miyamoto Musashi ran in the Asahi Shimbun from 1935 to 1939 — four years of daily installments during wartime, reaching virtually every literate household in Japan. Yoshikawa wrote later that the story’s influence had grown far beyond what he’d intended. He described receiving letters from readers who said the book had pulled them back from the edge of suicide. Rather than pride, he felt what he called “苦痛にも似た自責” — a self-reproach resembling pain — because he knew how much of what he’d written was invention.
The Wikipedia entry on the historical Musashi states plainly that the Yoshikawa novel is famous but contains much that diverges from the historical record. Before Yoshikawa, Musashi existed mainly as a figure of violent legend in popular storytelling. The novel gave him interiority, spiritual aspiration, and a love story. It transformed him from a legendary killer into something closer to a Japanese saint — a man seeking 剣禅一如 (the unity of sword and Zen) through a lifetime of ascetic discipline. The Wikipedia entry on Musashi notes that he is now referred to as “剣聖” (sword saint) in modern usage — a term that owes more to Yoshikawa than to the historical record.
That image is now so dominant that many Japanese people who know Musashi’s name have never read The Book of Five Rings. The Yoshikawa version is what people know. It has largely replaced the historical record.
What Itagaki actually brought back
Itagaki’s Musashi is built around historical embarrassments the Yoshikawa tradition ignores entirely.
The real Musashi, despite being the most famous swordsman of his era, spent his life unable to secure stable employment as a retainer. He was never given a proper domain. He wandered. Threads on Japanese anime and manga communities on the arc caught something Western coverage mostly missed: Itagaki’s clone Musashi is written with this detail intact. In his internal monologues, he boasts constantly about his fame and legend. In the objective scenes, he’s getting awkward looks from feudal lords for his complete inability to read social situations. One Japanese anime and manga communities user observed that this tracks directly with why the historical Musashi never actually got hired — he was impossible to have around.
Itagaki even commented in a volume margin note that he’d done a name-reading divination on “Miyamoto Musashi” and gotten “extreme show-off” as the result. “やっぱりな,” he wrote. Figured as much.
The Yoshikawa Musashi is humble, inward, perpetually refining himself toward a spiritual ideal. Itagaki’s Musashi is vain, status-hungry, and constitutionally unable to fit into any social structure that doesn’t involve him being recognized as the best at killing people. These are not variations on the same figure. They’re two different arguments about what he was.
The wartime problem Yoshikawa couldn’t escape
The novel was serialized during Japan’s military expansion into China. A Musashi who sought spiritual perfection through the sword, who disciplined himself toward a Buddhist ideal — that was a useful story for a country asking its young men to see military service as self-cultivation. Yoshikawa was aware of this. His preface returns to the gap between his fictional Musashi and whatever the historical person actually was with something close to anxiety.
Itagaki’s Musashi walks into modern Tokyo and starts killing people because that’s what the historical record suggests a man with his background might actually do. The scene where Yujiro sweats at the name “Miyamoto Musashi” — described in the Pixiv encyclopedia entry on clone Musashi as the “宮本武蔵というブランド” (the brand that is Miyamoto Musashi) — is Itagaki acknowledging directly what makes Musashi threatening. Not his actual character. The accumulated weight of ninety years of myth. Yujiro doesn’t sweat at the man. He sweats at the brand.
The Japanese anonymous board retrospective threads on the arc are warmer in hindsight than the real-time reaction was: “武蔵のデザインはほんと好き / 宮本武蔵のイメージは完全にあれで固定されたわ” — I love Musashi’s design / that image has now permanently replaced what I had before.
That’s the strange final result. Itagaki drew a Musashi who refuses the saint image, and Japanese readers responded by replacing their saint image with his version anyway.
Yoshikawa worried his novel would be mistaken for history. He was right to worry. Itagaki may have done it again.
