Tokunō Sekishirō

11 July 2026

Tokunō Sekishirō (得能関四郎, 1842–1908; imina Michihisa 通久) was a Keishichō gekken instructor who received both the first seirenshō and the first hanshi title from the Dai Nippon Butokukai, and was reckoned the foremost of the “three elders” of the Tokyo kendō world. His swordsmanship was Jikishinkage-ryū of the Naganuma line — which places a second Naganuma-ha figure, after Kawaji, at the heart of the Meiji police layer.1

Born the son of a samurai of the Numata domain, he entered at fifteen (1856) the Shiba-Atago dōjō of the domain’s Jikishinkage-ryū instructor Naganuma Masabei (Junkyō), took full transmission (menkyo kaiden) at twenty-one in 1862, and after his teacher’s death studied under the son, serving as juku-head of the Naganuma dōjō. After the abolition of the domains he became a city warden in Tokyo, and in 1880 was taken into the Keishikyoku as a guard-officer (警衛掛); as a gekken sewakari he joined in compiling the Keishi-ryū (Japanese Wikipedia, n.d.; Japanese Wikipedia, n.d.). His match record ran strong through the 1880s — an 1882 imperial-review win, and a victory over Matsuzaki Namishirō at the 1884 Yayoi national tournament among them.

At the first Butoku-sai great embukai in 1895 he defeated Okumura Sakonta and was awarded the first seirenshō (精錬証); across the following annual meetings he was never beaten, and in 1903 he received the Butokukai’s first hanshi (範士) title (Japanese Wikipedia, n.d.; Dai Nippon Butokukai (大日本武徳会), n.d.). In his last years he was named foremost of the “three elders of the Tokyo kendō world” (東都剣道界の三元老), the other two being Shingai Tadaatsu (真貝忠篤) and Negishi Shingorō. On an early morning in July 1908 he took his own life at home by cutting his throat — leaving no note, the act was ascribed to the stroke he had suffered that spring — at the age of sixty-seven.2

Open Questions

  • The Naganuma-ha teacher’s name is given variously (Naganuma Masabei / Junkyō / Junkō / Shōbei 恂郷・恂教・笑兵衛); fix the reading and the exact figure against a Jikishinkage-ryū transmission source, since it bears on which sub-line of the Naganuma-ha he carried.
  • The death date is given as 1 or 17 July 1908 across sources; resolve if a primary allows.

End Notes

  1. The Naganuma-ha of Jikishinkage-ryū is the same broad school this register otherwise follows, but a distinct sub-line from the Odani-ha / Fujikawa-ha; Tokunō and Kawaji together give the police layer two Naganuma-ha swordsmen, which is worth noting against the assumption that the Keishichō drew only from the sword schools popular in Edo. (Japanese Wikipedia, n.d.) ↩

  2. The seppuku is reported consistently — the blade wiped and returned to its sheath before death — but the cause is given as uncertain, most often attributed to the stroke of that spring; treat the “no reason known” framing as the sources leave it rather than resolving it. (Japanese Wikipedia, n.d.) ↩
