was a famous swordsman of the early Sengoku period. He was described as a kensei (sword saint). He was the founder of a new Kashima style of kenjutsu, and served as an instructor of Shōgun Ashikaga Yoshiteru and Ise provincial governor daimyō Kitabatake Tomonori. Early life Bokuden was born into the Yoshikawa family within the Hitachi Province of Honshu. The family was one of four Karō families serving the Kashima clan; one of the cadet branches of the Imperial House of Japan (descendants of the ). Bokuden was adopted by the Tsukahara family, an offshoot of the Kashima clan; he was styled as Tsukahara Bokuden Takamoto. Earlier in his life, his name was Tsukahara Shin'emon Takamoto. Career Bokuden learned the Tenshin Shōden Katori Shintō-ryū from his adopted father and later honed his skills by engaging in musha shugyō (warrior's ascetic training), traveling throughout Japan and training with most of the skillful and knowledgeable swordsmen of the day. Tsukahara Bokuden was the classic knight-errant; a rich nobleman, he travelled the Japanese countryside, often with a full entourage. He later systematized the teaching of the Kashima area's local martial arts, including such approaches to combat as Kashima no tachi and Ichi no tachi. After allegedly receiving a divine inspiration from Takemikazuchi no kami, the deity of Kashima Shrine, he named his martial system as Kashima Shintō-ryū. He also, for a brief period, called his system Mutekatsu-ryū ("winning without hands"). In one anecdote recorded in the Kōyō Gunkan, Bokuden was challenged by a mannerless ruffian. When asked about his style, Bokuden replied that he studied the "Style of No Sword". The ruffian laughed and insultingly challenged Bokuden to fight him without a sword. Bokuden then agreed to fight the man without his sword but suggested they row out to a nearby island on Lake Biwa to avoid disturbing others. The ruffian agreed, but when he jumped from the boat to the shore of the island, drawing his blade, Bokuden pushed the boat back out, leaving the ruffian stranded on the island. Bokuden explained: "This is my no-sword school". Bruce Lee was so fond of this story that in Enter the Dragon (1973) he teaches a bully a lesson about "Fighting without Fighting" when he offers to leave a junk and sail to an island. There is a fictional story that the young Miyamoto Musashi challenged Bokuden to a duel during a meal. When
