Terao Magonojō
寺尾孫之允
Miyamoto Musashi's Chief Disciple Who Received the Book of Five Rings Days Before Musashi's Death, First Grandmaster of the Niten Ichi-ryū
Description
Life
Born in 1611 as the son of a warrior serving the Hosokawa house of Higo Kumamoto domain. Because he was hard of hearing, he was unable to serve the domain in office and is said to have lived in retirement near Kumamoto castle town, farming for his livelihood.
Meeting Miyamoto Musashi and Receiving the Book of Five Rings
In 1640, he became a disciple of Miyamoto Musashi, who had been invited to Kumamoto domain as a guest, and studied strategy under him for the following five years. On the twelfth day of the fifth month of Shōhō 2 (June 5, 1645), seven days before Musashi's death, Magonojō received from him the treatise Go Rin no Sho (The Book of Five Rings) along with the Dokkōdō. He was one of the very few senior disciples to directly inherit Musashi's teachings in his final days.
Transmission of the Niten Ichi-ryū
After Musashi's death, Magonojō served as the first grandmaster of Niten Ichi-ryū strategy, preserving and transmitting its teachings in Higo. He passed on the Go Rin no Sho to disciples including Urakami Jūbei and Shibatō Sanzaemon, remaining the center of the school until his death in 1672.
Connection to Swords
The two-sword technique of Niten Ichi-ryū is known as a distinctive sword theory grounded in Musashi's own combat experience. Magonojō was the figure who reliably transmitted this technique and philosophy to later generations in written form, and is regarded as one of those most responsible for preserving Musashi's sword philosophy for posterity through the Go Rin no Sho.
Later Reputation
Together with the line of his younger brother Terao Kyūmanosuke, the Niten Ichi-ryū that Magonojō transmitted survived in Higo Kumamoto and continues to be passed down to this day. The survival of the Go Rin no Sho itself is owed entirely to Musashi's transmission to Magonojō, and he is highly regarded as the inheritor of Musashi's thought in the history of Japanese swordsmanship.
