SECTION V -- FIELD NOTES
[A]The Mutekatsu-ryū Story
In his old age, Bokuden was challenged on a lakeboat by a young swordsman of another school. Bokuden proposed that they fight on a sandbar, and the young man jumped from the boat first. The moment he did, Bokuden ordered the boatman to push off from the shore. Calling to the now-stranded young man, Bokuden declared, 'This is my Mutekatsu-ryū — the school of winning without fighting.' The anecdote crystallizes the idea of victory without drawing the sword and has had a strong influence on later Japanese martial-arts thought.
SECTION VI -- LEGACY & IMPACT
Bokuden's unbeaten life mixes historical fact and legend, but the Kashima Shintō-ryū lineage had a direct influence on the major Edo-period sword schools that followed. Ashikaga Yoshiteru, the so-called 'sword-saint shogun,' is said to have learned from Bokuden, as was Kitabatake Tomonori of Ise. The Bokuden Hyakushu — a collection of didactic poems compiled in his name — is regarded as the first systematic articulation of swordsmanship as something larger than victory, and is still quoted in modern budō philosophy.

From Kashima to Everywhere: How Bokuden Created the Itinerant-Training Tradition
Tsukahara Bokuden spent most of his life at Kashima Shrine, but in his later years he traveled the provinces training students. The itinerant-training tradition he established laid down the route the later swordsmen — Kamiizumi Nobutsuna, Miyamoto Musashi — would all follow, and became the standard form of Japanese martial-arts training.

The thirteenth Ashikaga shogun, Yoshiteru, is the figure known as the 'sword-saint shogun.' His sword talent is said to have been transmitted from both Tsukahara Bokuden and Kamiizumi Nobutsuna. When Yoshiteru was killed in the 1565 Matsunaga Hisahide raid, his sword resistance to the end was the embodiment of what Kamiizumi had taught him.
