The Priest-Uncle

The priest-uncle is a monk who, in a 1727 account, is the brother of Musashi's mother. He tries to apologise for the boy before the fight with Arima. No source gives his name.

Who he was

Evidence grade: Traditional · Later accounts

In the only source that mentions him, he has no name. The 1727 book says the boy had a maternal uncle, a priest who lived in a small hermitage in Harima. That is all it says about him.

We do not know his age, his temple, his face or his given name. We do not know whether he was a real person. The 1727 book was written by a Chikuzen follower of Musashi's school, about 130 years after the event.

Modern signboards in Hirafuku give him a name, a temple and a family. None of that is in the 1727 text. The project could trace the name no earlier than modern local signs. It is graded legend, and this site does not use it.

The film shows him as a thin, worried monk of about fifty in a plain dark robe. That look was invented for the episode. No source describes him.

The road to the fight

Evidence grade: Traditional · Later accounts

In the 1727 account, the uncle enters the story after the boy blacks out Arima's notice board. In the evening Arima's messenger comes to accept the challenge. The uncle is frightened. He goes with the messenger to Arima's lodging and asks pardon for what he calls a child's mischief.

Arima answers that he has nothing more to demand. But his notice was blacked out, and he cannot excuse himself to people. He asks the uncle to bring the boy to the fenced ground the next day and to make the apology there, in front of everyone.

The next morning the uncle tells the boy that he is making him suffer for nothing, and tells him to follow. The boy follows, leaning on a stick taken from the firewood.

The film shows him bowing to the floor at Arima's lodging. The bow is the film's staging. The book says only that he begged pardon.

The moment

Evidence grade: Traditional · Later accounts

At the ground, the uncle stands with a hand on the bamboo fence and begs pardon. The 1727 account says this is the moment the boy arrives, pushes open the gate and runs in. The text does not say what the uncle does next, and it does not say what he feels.

The same account says that after the fight the boy reflected: if he threw away his life and simply stepped in to strike, beating an enemy would take no trouble. He left his uncle and went round the country for sixteen years.

No other early source mentions the uncle. Musashi's own book does not. The 1654 monument does not.

In the film, the uncle begins to bow and the boy walks in past him. The exact order of those movements is the film's own staging. The account says only that the boy came while the uncle was begging pardon.

How we know

Evidence grade: Traditional · Later accounts

The uncle rests on one book. A modern analysis reads the 1727 story as a folk legend taken into the book. Its shape is that of a folk tale: a taboo broken, a substitute father, a public sacrifice. That does not make the uncle false. It means we cannot treat the scene as a report.

The local signboards in Hirafuku tell a different story. They say the boy's father died when the boy was seven, and that the boy was then placed with a relative. The 1727 book has the father drive the boy away at nine. Documents reported in a standard biography show the father alive in 1607 and 1613. The signboard and the 1727 book cannot both be right.

For these reasons the series gives him no name. A name the sources do not support would be an invention presented as history.

Sources

  1. Tachibana (Tanji) Hokin, Tanji Hokin Hikki (also titled Heiho Taiso Bushu Genshin-ko Denrai) (1727)

    Later tradition · The earliest surviving written version of the Arima story and the source of the pine fight in Episode 2. Written about 130 years after the Arima bout. Read through a modern scholar's transcription of the Yoshioka passage (linked; archived copy); the manuscripts were not seen. The date of the Yoshioka passage is inferred.

  2. Information boards at the Hirafuku 'Musashi duel site' and Shoren-an, as transcribed on a travel site (hyoutabi.com)

    Later tradition · Modern local signboards. They give the priest-uncle a name and a family. That name is not in the 1727 text and is not used on this site. The boards also conflict with the 1727 story and with dated documents on Musashi's father.

  3. Suzuki Koji / Harima Musashi Kenkyukai, Miyamoto Musashi research site (Go Rin no Sho edition and source commentary, musasi.siritai.net) (2003-16)

    Modern work · A private research site, careful about manuscript variants and quotations. The site did not load from the project's computers on 20-10-2026 and 30-10-2026; pages were read earlier or through the Internet Archive. It argues its own positions, so contested points need a second source.

  4. Uozumi Takashi, Miyamoto Musashi: 'Heiho no michi' wo ikiru (Iwanami Shinsho) (2008)

    Study · A standard university-press biography. Not read directly: the points taken from it (birth year, Munisai's dated documents, the Hosokawa stipend) were read through Japanese Wikipedia, which gives page numbers.

  5. Samurai Retold research notes on portraits and likenesses of Musashi, Arima Kihei and Kojiro (2026)

    Modern work · The series' own notes on what images survive. No portrait made from life survives for any of them. The film's faces are design choices.

Musashi's First Fight

Miyamoto Musashi later wrote that he fought more than sixty times and never lost. The first, he said, was against a grown man called Arima Kihei, when he was thirteen. The episode tells that fight as a later account describes it, then shows how much of it the older sources support.
