When Jiki Shinkage-ryū’s divisions are studied systematically, the taxonomy is consistently three lines — Naganuma-ha (長沼派), Fujikawa-ha (藤川派), and Odani-ha (男谷派), with the orthodox Naganuma house sometimes set apart as the trunk.
The peer-reviewed treatment, Karukome Katsutaka’s “A study of the branches of Jiki Shinkage-ryū,” analyzing the training and inter-school match characteristics of the Naganuma, Fujikawa, and Odani groups (Budōgaku Kenkyū 46(1), 2013), and the same author’s AJKF column, which states flatly that in the late early-modern period the school divided into those three branches.
Dōtō
Orthodox dōtō (formal styles; dates where firm) leading to the Edo area Jikishinkage-ryū:
- Matsumoto Bizen-no-kami Masamoto (松本備前守政元) — ryūso; reading Matsumoto/Sugimoto contested
- Kamiizumi Ise-no-kami Nobutsuna (上泉伊勢守信綱)
- Okuyama Kyūgasai Kimishige (奥山休賀斎公重), 1526–1602
- Ogasawara Genshinsai Nagaharu (小笠原源信斎長治)
- Kamiya Denshinsai Sanemitsu (神谷傳心斎真光)
- Takahashi Jikiōsai Shigeharu (高橋直翁斎重治), tsūshō Danjōzaemon — founder of Jikishin Seitō-ryū (直心正統流)
- Yamada Ippūsai Mitsunori (山田一風斎光徳) — named the school Jiki Shinkage-ryū
- Naganuma Shirōzaemon-no-jō Fujiwara no Kunisato (長沼四郎左衛門尉藤原国郷), 1688–1767
- Naganuma Shōbee-no-jō Katsuzensai Fujiwara no Tsunasato (長沼庄兵衛尉活然斎藤原綱郷) — dates unknown

Naming Conventions
Historical names have several portions or variants:
- gō (号; art-name / sobriquet)
- imina (諱; true given name / “taboo name”)
- tsūshō (通称; common name / by-name) — the everyday name plus any titular suffix, e.g. Shōbee-no-jō (庄兵衛尉).
The gō is a self-chosen style-name, usually ending in -sai (斎), -an (庵), and the like; the master’s “studio name.” In this house, Katsuzensai (活然斎), Shinpansai (真帆斎), Seisai (静斎), Ittokusai (一徳斎).
The imina, the real personal name, used formally and posthumously but avoided in direct address in life (hence “taboo”). This is the element carrying the Naganuma generational character 郷 (sato): Kunisato (国郷), Tsunasato (綱郷), and so on.
The tsūshō is the common name, the everyday name plus any titular suffix, e.g. Shōbee-no-jō (庄兵衛尉).
A full name would read tsūshō + gō + uji + imina. For example, Naganuma Shōbee-no-jō (tsūshō) Katsuzensai (gō) Fujiwara Tsunasato (imina).
Fujikawa-ha
The Fujikawa-ha today is best remembered for the historical record. The Jikishinkage-ryū Kenjutsu Gokui Kyōju Zukai (直心影流剣術極意教授図解) by Saitō Akinobu, original edition from Meiji 34 (1901), published by Iguchi Kaishin Shorō, with a classical-Chinese postface by Tsuda Kanjirō (reprinted by Shimazu Shobō, 2003), preserves a view of its teachings.
Fujikawa Seisai (1791–1862) reshaped the branch’s philosophy. Drawing on Seisai’s own writings — particularly the Reiken Ryakkai (霊剣略解, 1857) — Karukome shows that Seisai explicitly criticized the contemporary obsession with competitive victory and made kata practice the primary vehicle for spiritual cultivation.
Yamada Jirōkichi studied Fujikawa-ha in addition to his time spent learning from Sakakibara. With Sakakibara’s permission, he studied kata under Yamada Hachirō (山田八郎). For this reason there is a view that what Yamada transmitted differs from the Odani-ha as it stood before Sakakibara. Ishigaki maintains that Yamada Jirōkichi trained under Saitō Akinobu and the dissertation of Karukome does not weigh in on that fact.
Odani-ha
For the Odani-ha today, Yamada Jirōkichi is regarded as the 15th-generation head, and carried the art onward into modern kendō. The Odani-ha is also the branch the literature credits with re-centering the school on the seigan stance for shinai matches and flourishing during the bakumatsu.
Yamada lost his Jikishinkage-ryū densho in the 1923 Great Kantō Earthquake. His line holds that there is currently no sōke of Jiki Shinkage-ryū kenjutsu, and after him his students Katō Kanji, Ōnishi Hidetaka, and Ōmori Sōgen taught the Hōjō kata in various places.
Each faction descending typically speak in terms of dōtō or keishō and not a sōke.
Modern Revial
The following is not from primary academic sources but rather contemporary history. It is influenced by my own perspective on the art. In summary:
- Yamada’s line was revived postwar as the Jikishinkage-ryū Hyakuren-kai in 1956. This effort fragmented with the death of Ōnishi Hidetaka, with Iwasa Masaru and Namiki Yasushi establishing separate schools.
- The line of Namiki was regarded as the Seito-ha by others, although it did not use that name itself. They were recognized by Kashima Shrine as a lineal succession of the art.
- Namiki was succeeded by Itō Masayuki. That line split with the death of Itō – the sons of Namiki Yasushi founded their own dojo, Yoshida Hajime (吉田基) continued the Tokyo dōjō.
- Iwasa Masaru continued practice under the name Hyakuren-kai and was recognized by the Nihon Kobudo Shinkokai. His line similarly split into multiple factions after his death.
Naganuma-ha
The Numata branch of the Naganuma house — the 正兵衛家 (別家長沼派) — lapsed during the early Meiji period. Its last head, Naganuma Michisato (称郷, gō Kashōjin) — the fifteenth holder in this branch’s continuation of the school’s generational count — abandoned the transmission of kenjutsu at the abolition of the domains. The Naganuma family line as Numata-han instructors thus discontinued its own headship, while the genealogical head house (四郎左衛門家) continued separately in Kanō (see below), and other lines carried the practice onward.
Jikishinkage-ryū Hisho (ichi) (直心影流秘書一) lists seven kata categories for this line of practice:
- Hōjō
- Tō-no-kata
- Koryū
- Habiki
- Kodachi
- Marubashi
- Saya-no-uchi
It notes Habiki has no forms of its own but borrows the five Koryū forms. In the Odani-ha/Fujikawa-ha contemporary practice Habiki is an arrangement of four kata performed in three continuous parts (smoothly moving from summer to autumn).
The same work begins its saya-no-uchi section with “鞘ノ内三” denoting it may be a small set of three kata, or three sets of kata – the latter distinction is unclear. A Naganuma manual titled saya no uchi is found in Japanese library holdings. It contains 54 kata, according to 河崎藤之丞義追’s 『鞘之内秘伝書』 (鈴鹿家文書, AJKF), and its transmission flows through Naganuma Tadasato.
According to Karukome, the branch survives as the Tōkyō Naganuma Shōbee-ke (東京長沼正兵衛家), the present-day Tokyo branch of the family. Karukome cites the family as the holder of the school’s oldest originals (Mitsunori’s 『兵法雑記』, Takahashi’s 1686 『稽古法定序幷理歌』, the 1773 『大禾一件』). Karukome bases his analysis on Nakamura Tamio (中村民雄), “幕末関東剣術流派伝播形態の研究(2),” 福島大学教育学部論集 社会科学部門 第66号, 1999.
The dissertation of Karukome provides much information.
Kunisato (国郷), 1688–1767 — 8th generation; full style 長沼四郎左衛門 尉藤原国郷, tsūshō Shirōzaemon (四郎左衛門). Third son of Yamada Mitsunori; received the school from his father in 1708, went to Edo, refined the bōgu and shinai, and died Meiwa 4 (1767) on the 24th of the 7th month (one account says 10th), aged 80, from Shimotsuke.
Naganuma practice consists of two houses, the Shirōzaemon-ke (四郎左衛門家) blood line or head house (宗家長沼派) and the Shōbee-ke (正兵衛家) adopted line or branch house (別家長沼派).
Naganuma Shirōzaemon-ke 四郎左衛門家
The line transmitted through Kanō-han in Mino
The Shirōzaemon-ke is often called the Sōke Naganuma-ha (“head-house” Naganuma branch) and is the main line that went to Mino Kanō and culminated in the well-known early 20th century shiai competitor Wasato.
Tokusato or Norisato (徳郷; 1741–1777, d. age 36) is Kunisato’s biological son, born in his father’s late years; learned the school from Tsunasato, and through the Nagai lords’ transfer to Mino became the root of the Kanō-han Naganuma line. It can be a bit confusing: genealogically the biological son, Tokusato, heads the main house (宗家 / 四郎左衛門家), while the adopted Tsunasato’s descendants form the branch (別家 / 正兵衛家). The formal dōtō, however, ran the other way — Kunisato (8th) to the adopted Tsunasato (9th) to Fujikawa (10th) — so the school’s headship succession passed through Tsunasato and bypassed Tokusato’s line entirely.
The Kanō-han (分限帳) line began when Nagai Naotsune (尚庸, 1631–1677), third son of Nagai Naomasa, was granted 20,000 koku in Kawachi in 1658; the Nagai (永井) house then moved through Shimotsuke Karasuyama, Harima Akō, and Shinano Iiyama into Musashi Iwatsuki, and under the fourth lord Naonobu (直陳) settled at Mino Kanō at 32,000 koku, remaining there with no further transfer to the end of the Edo period.
Yamada Mitsunori had been an Edo-duty retainer of the Nagai at Musashi Iwatsuki, so the sword house was a Nagai retainer family from the start. When the Nagai went to Kanō, Tokusato went with them as the domain’s hereditary Jiki Shinkage-ryū instructors, while Tsunasato’s branch instead took service at Numata.
Tokusato’s tsūshō is Shirōzaemon (四郎左衛門), the hereditary by-name of this head house — the dissertation styles him 四郎左衛門徳郷. As with any such house name, it was re-used across generations, with individual teachers disambiguated by their imina when available. (The Shōbee tsūshō — 正兵衛, with the Issei-kai variant 庄兵衛 — belongs instead to Tsunasato’s branch house, discussed below.)
- Kunisato (1688–1767)
- Tokusato (徳郷, 1741–1777)
- Sadasato (貞郷, d. 1781; great-grandson of Yamada Mitsunori)
- Sukesato (亮郷)
- Kazusato (万郷)
- Yasusato (楽郷, eldest son, died young)
- Wasato (和郷, hanshi 1925, second son)
- Akisato (昭郷)
The early 20th-century Wasato (和郷) was named hanshi by the Butokukai in 1925 and continued this branch to Akisato, who is the last recorded master.
Naganuma Shōbee-ke 正兵衛家
The line transmitted through Edo and the Numata-han.
Shōbee-ke (the Shōbee house) also labeled Bekke Naganuma-ha (別家長沼派; “branch-house” Naganuma branch). This is the cadet line that is Numata-affiliated and is the line the 1800 densho I studied comes from.
Tsunasato (綱郷), dates not found — 9th generation; full style 長沼 庄兵衛尉活然斎藤原綱郷 — tsūshō Shōbee-no-jō (庄兵衛尉), gō Katsuzensai (活然斎).
Adopted son of Kunisato (original name is Saitō Yūgorō). He took service with Numata-han, after which the Naganuma house taught there for generations. He served Toki Yoritoshi of Numata from 1723; stayed Edo-resident when the Toki moved to Numata in 1742; after Kunisato died in 1767 he went independent, opened the Shiba Atago-shita dōjō and taught around 3,000 students.
It is in this line we see the tsūshō Shōbee (正兵衛) being used.
The adopted man (Tsunasato) actually carried the school first, as a stand-in while Kunisato was old and childless — but once the blood son (Tokusato) was born and grew up, the blood son took the head house (Shirōzaemon-ke) and the adopted man’s descendants became the branch (Shōbee-ke). So it still follows the normal rule of blood being head, adopted being a branch. It is the case that the adopted line has seniority in time of training.
Numata-han Jikishinkage-ryū
The Naganuma family were Numata-han instructors, beginning with Naganuma Tsunasato, adopted heir of Naganuma Kunisato, who took service with Numata-han. The Numata-han taught Jikishinkage-ryū for several generations thereafter.
Karukome’s analysis of the 正兵衛家 branch line runs:
- Tsunasato (綱郷) — orig. Saitō Yūgorō; Kunisato’s daihiko; served Toki Yoritoshi (of Numata) from 1723; stayed Edo-resident when the Toki moved to Numata in 1742; after Kunisato died in 1767 he went independent, opened the Shiba Atago-shita dōjō, ~3,000 students.
- Tadasato (忠郷) — succeeded Tsunasato; already the 正兵衛 by 1773 (the dissertation names him as the Shōbee in the 1773 Ōga/Momoi match), issuing licenses through the Kansei era.
- Naosato (直郷, adopted) — shihan until 1819, then retired to Numata.
- Takasato (孝郷) — d. 1827, no heir.
- Terusato (輝郷) — d. 1831, age 26.
- Junsato (恂郷) — the Numata-han instructor whose dōjō Tokuno Sekishirō entered.
- Shōkyō (称郷 furigana みちさと, alt. Shōkyō, gō 可笑 Kashōjin) — closed the dōjō at the abolition of the domains and 1876 haitōrei.
Tadasato is the author of the 1800 densho I previously studied.
The 正兵衛家 line dōjō was located at Edo Mizaka ( 江戸見坂 ), inside the Numata domain’s Edo residence. Tadasato held the 正兵衛 name across the entire Kansei era (license to Kawasaki in 1789, students through ~1801), the 寛政十二 (1800) Hōjō transmitted at Edo Mizaka by 長沼正兵衛 is 忠郷 (Tadasato).
Other Influences
Isezaki Araki-ryū’s central line, started by the 9th-generation shihan Komine Bundayū and his student Kurihara Ioji (Gomoji) Masashige, developed many of its weapon-on-weapon kata through exchange with the neighboring traditions of the area, most notably Kashima Shinden Jikishinkage-ryū and Kiraku-ryū.
The flagship Sakai domain — Shōnai (Tsuruoka), with its han-school the Chidōkan — maintained a line of Jiki Shinkage-ryū. Onozaki Norio’s Shōnai-han no bujutsu (庄内藩の武術), compiled from the Chidōkan and the Tsuruoka/Sakata archives, lists the domain’s kenjutsu lines as Shinkyū-ryū, Okuyama-ryū, Santomi-ryū, Inazuma-ryū, Shinshin Yagyū-ryū, Tamiya-ryū, and Jiki Shinkage-ryū
Jikishinkage-ryū was also taught in other domains, besides Numata. Fujikawa Seisai (1791–1862), after the 1853 arrival of the American ships, was invited by the Tōdō house (藤堂家) Tsu-han in Ise and the Yanagisawa to instruct their retainers. The Sakai family from Tsu-han continued a practice of Jikishinkage-ryū kenjutsu.
