Factions of Jikishinkage-ryū

↑

When Jikishinkage-ryū’s divisions are studied systematically, the taxonomy is consistently three lines (opens in a new tab):

• Naganuma-ha (長沼派)
• Fujikawa-ha (藤川派)
• Odani-ha (男谷派)

The orthodox Naganuma house is sometimes set apart as the trunk, historically. The Odani-ha embraced competitive matches and was involved with the Tokugawa Kōbusho.

The main Naganuma-ha lineage ended with the banning of the wearing of swords during Meiji, but a small family branch continues to this day.

The Fujikawa-ha continued through early Meiji and was survived by merging into the Odani-ha to become Yamada Jirōkichi’s Seito-ha. It is also claimed to have an influence on the Kashima Shin-ryū of Kunii Zen’ya.

Another faction, the Nomi-ha, ceased practice after WWII but produced publications detailing much of its densho. The Seito-ha itself further fragmented after martial arts practice was resumed after the restrictions imposed during Allied occupation.

The main peer-reviewed treatment, Karukome Katsutaka’s “A study of the branches of Jikishinkage-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.

Note that both load-bearing antiquity claims of the Kashima-shinden framing — the Sengoku founder Matsumoto and the divine Kashima descent — are documentary additions made by Naganuma Kunisato in the mid-eighteenth century, contemporaneous with the doctrinal cluster of later topics (相尺・留三段・切落・吟味, and the 十之形 龍尾–曲尺) being added to the mokuroku kuden-sho and absent from Yamada’s Heihō zakki.

Before this time, Ogasawara refered to himself as the founder of his art, citing his travels to China. Ogasawara’s 1673 menjō describes him as having found the art himself and cites a crossing abroad (異朝渡). This nittō motif is in the primary densho at the early 17th century Ogasawara stage, not a later gloss made in order to gain reputation by association with late-Ming dynasty.

Kamiya similarly regards himself as founding his art, having studied fifteen ryūha. Later masters regard then Kamiya as the art’s successor until Naganuma Kunisato revises the arts curriculu and rewrites its history, inserting Matsumoto (Sugimoto) Bizen-no-kami Masamoto (松本備前守政元) as ryūso in 1768 and likely inventing the notion of divine revelation from Takemizukachi-no-kami.

So, in the table above, when comparing against commonly available sources, one would need to increase the generation by one to account for the insertion of Matsumoto by Naganuma.

Also, Ogasawara viewed his approach as his own, and so did Okuyama and Kamiya. I believe this is a witness to a transition of thinking from late Muromachi period practice of swordsman who saw combat, developing unique experiences and insights, and later Edo-period professional swordsmanship instructors who institutionalized these earlier methods. The hinge from the personal to the institutional lies in Takahashi, who called his line Jikishin-shōtō-ryū (orthodox).

An interesting note is that Nagunuma reaches back to Matsumoto, whereas Kamiizumi learned likely from Bokuden (based on his birth and death dates not matching well with Iizasa Choisai), and maintained both the Aisu Kage-ryū content of Empi and Tengushō in his early teaching, as well as the Shintō=ryū nanatachi as an important upper-level set, as well as his own Sangakuen, Kuka, and Marubashi teachings.

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; abstinence/ritual purity), -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.

The Hyakuren-kai does not view Kawashima as the 16th generation head, but instead maintained that the art’s transmission ended and was revived by Ōnishi Hidetaka, and then passed into their own lineage. Iwasa Masaru continued practice under the name Hyakuren-kai after the death of Ōnishi and was recognized by the Nihon Kobudo Shinkokai. His line split into multiple factions after his death.

The line through Namiki Yasushi listed above was regarded as the Seito-ha, 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 (opens in a new tab) and was recognized by the budō community as being the 20th head.

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 Shōkyō (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; Shirōzaemon family house) 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:

1. Hōjō
2. Tō-no-kata
3. Koryū
4. Habiki
5. Kodachi
6. Marubashi
7. 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 sōke (宗家 / 四郎左衛門家), while the adopted Tsunasato’s descendants form the bekke (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 Jikishinkage-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.)

1. Kunisato (1688–1767)
2. Tokusato (徳郷, 1741–1777)
3. Sadasato (貞郷, d. 1781; great-grandson of Yamada Mitsunori)
4. Sukesato (亮郷)
5. Kazusato (万郷)
6. Yasusato (楽郷, eldest son, died young)
7. Wasato (和郷, hanshi 1925, second son)
8. 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 Saitō Yūgorō); his fuller biography appears in the branch-line list below.

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), even though the adopted line had 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:

1. 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.
2. 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.
3. Naosato (直郷, adopted) — shihan until 1819, then retired to Numata.
4. Takasato (孝郷) — d. 1827, no heir.
5. Terusato (輝郷) — d. 1831, age 26.
6. Junsato (恂郷) — the Numata-han instructor whose dōjō Tokuno Sekishirō entered.
7. Shōkyō (称郷, 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 Jikishinkage-ryū. Onozaki Norio’s Shōnai-han no bujutsu (庄内藩の武術; Shōnai domain martial arts), 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 Jikishinkage-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; Tōdō family house) Tsu-han in Ise and the Yanagisawa to instruct their retainers. The Sakai family from Tsu-han continued a practice of Jikishinkage-ryū kenjutsu.
