Selected Kenshi

11 October 2026

From the research for my book From the Kōbusho to the Butokukai: Swordsmanship in Transition on 19th and 20th century Japanese swordsmanship.

While researching the Kōbusho and what followed it, I kept a record for each practitioner I came across: his names, dates, school and teachers, and what the sources say of him. The fuller records are gathered here, in order of birth. They are working notes more than biographies, and each says what it rests on.

  • Kubota Sugane (窪田清音; 1791–1867), Tamiya-ryū. Tenth-generation head of Tamiya-ryū and a founding tōdori of the Kōbusho, who taught military science rather than a weapon there and left some hundred and thirty works.
  • Chūjō Kinnosuke (中條金之助; 1827–1896), Shingyōtō-ryū, Hokushin Ittō-ryū, Totsuka-ha Yōshin-ryū. Bakumatsu bannerman (1827-1896) and one of the few Kōbusho men to teach in two disciplines, kenjutsu and jūjutsu; after the Restoration he headed the Seiei-tai guard and led the former retainers who reclaimed the Makinohara plateau for tea.
  • Matsuzaki Namishirō (松崎浪四郎; 1833–1896), Katōda Shinkage-ryū. Matsuzaki Namishirō (松崎浪四郎, 1833–1896) of Kurume: his training in Katōda Shinkage-ryū, his musha shugyō and gekken years, the Shunpūkan, and his place in the early kendō world.
  • Takahashi Deishū (高橋泥舟; 1835–1903), Jitokuin-ryū, Ninshin-ryū. Some details on the Yūgeki-tai and the famous spear and calligraphy master Takahashi Deishū.
  • Yamaoka Tesshū (山岡鉄舟; 1836–1888), Jitokuin-ryū, Ninshin-ryū, Mutō-ryū. Some details on the famous sword and calligraphy master Yamaoka Tesshū.
  • Hakomori Yosaburō (箱守与三郎; 1837–?), Jikishinkage-ryū. Hakomori Yosaburō (箱守与三郎祐郷) taught Jikishinkage-ryū in Makabe-gun, Ibaraki, founded the Genbukan at Shimotsuma in 1904, and was the sword teacher of Nakayama Tatsusaburō.
  • Matsuoka Yorozu (松岡万; 1838–1891), Chūya-ha Ittō-ryū. Shogunal retainer, sonnō-jōi activist, and swordsman who led the Seiei-tai guarding the retired Yoshinobu.
  • Takahashi Hatsuji (高橋初次; 1838–?), Araki-ryū. Takahashi Hatsuji (高橋初次, b. c. 1838) was a former Hamada-domain retainer and senior disciple of the Araki-ryū jūjutsu master Fukui Ichirōemon. A Hamada-Prefecture police officer who later doubled as an instructor of jūjutsu and swordsmanship, he appeared at the age of sixty at the Dai Nippon Butokukai’s third Butokusai in Kyoto (1897), defeated his opponents, and received a Butokukai certificate for Araki-ryū jūjutsu.
  • Naitō Takaharu (内藤高治; 1862–1929), Hokushin Ittō-ryū. Hokushin Ittō-ryū swordsman from Mito (1862-1929) who, with Takano Sasaburō, shaped the kendō of the Dai Nippon Butokukai; as chief kendō instructor at its teacher-training school (the Busen) he formed the interwar generation of masters and carried Chiba Shūsaku’s lineage into modern kendō.
  • Takano Sasaburō (高野佐三郎; 1862–1950), Nakanishi-ha Ittō-ryū. Takano Sasaburō (高野佐三郎, 1862–1950) was one of the two principal architects of modern kendo. Born in Chichibu in Musashi province, he was trained from infancy in Nakanishi-ha Ittō-ryū (中西派一刀流) by his grandfather Takano Sakichirō, sword instructor to the Oshi domain. He later studied under Yamaoka Tesshū.
  • Chiba Shūsaku (千葉周作), Ittō-ryū, Hokushin Ittō-ryū. Chiba Shūsaku (千葉周作) — childhood name Ototsumatsu (於菟松), imina Narimasa (成政) — was the founder of Hokushin Ittō-ryū (北辰一刀流) and, through the Genbukan (玄武館), one of the most consequential kenjutsu educators of the late Edo period.
  • Iba Sōtarō (伊庭惣太郎), Shingyōtō-ryū. Ninth head of the Shingyōtō-ryū (1822-1886), formally Iba Gunbei Hidetoshi, who rose from disciple to be named heir over the previous head’s own son and served as a Kōbusho kenjutsu master-instructor.
  • Ido Kinpei (井戸金平), Hōzōin-ryū. Hōzōin-ryū spearman who threw the Kōbusho’s instructors at will with a foot-entanglement, until Takahashi Deishū forestalled it and the technique was given up.
  • Kunii Zen’ya (國井善弥). Examining the Kashima Shin-ryū of Kunii Zen’ya. Early influences, Shintō education, military contributions, martial reputation and memorial tributes provide a rich view of this important budōka.
  • Nakayama Hakudō (中山博道). Nakayama Hakudō, the Yūshinkan master who carried iai, jō and Ittō-ryū across the Taishō–Shōwa decades from inside the modern budō institutions — the institutional counterpart to Kunii Zen’ya’s outsider stance.
  • Nakayama Tatsusaburō (中山辰三郎), Ittō-ryū, Jikishinkage-ryū, Yōshin-ryū. Nakayama Tatsusaburō (中山辰三郎) was an important Shindō Yōshin-ryū (神道楊心流) figure and the teacher of Ōtsuka Hironori (大塚博紀) and studied Jikishinkage-ryū and Ono-ha Ittō-ryū.
  • Shimoe Hidetarō (下江秀太郎), Hokushin Ittō-ryū. Hokushin Ittō-ryū master (1848-1904), a Genbukan juku-head and formidable Meiji police gekken instructor famed for his thrust, who recruited Naitō Takaharu and Monna Tadashi into the Metropolitan Police and so became the conduit by which the Genbukan line passed to the Butokukai’s Mito leadership.
  • Yoshida Katsunosuke (吉田勝之助), Hōzōin-ryū. Hōzōin-ryū spear instructor at the Kōbusho, pupil of Inō Ichiunsai, whose bout with Ido Kinpei had to be defused by the academy’s superintendent.
