Identity & authority

Disambiguation

Jikishinkage-ryū (Odani-ha / Seitō-ha main line) swordsman, 1830–1894; low-stipend Tokugawa gokenin, Kōbusho kenjutsu instructor, head of the Yūgekitai, and organizer of the Meiji gekiken-kōgyō. 14th head of the main line; teacher of Yamada Jirōkichi.

Reliability

Core biography converges across the reference dictionaries and the NDL portrait resource. Flagged divergences: kabuto-wari year (1886 Kōdansha vs 1887 Nipponica / Nakabayashi); sibling count; successor's given-name orthography. The Takeda Sōkaku discipleship and the competing second-teacher claims for Yamada are contested.

Summary

Sakakibara Kenkichi (榊原鍵吉) was a Jikishinkage-ryū swordsman of the Odani-ha line who bridged the late-Tokugawa military-training apparatus and the early Meiji effort to keep swordsmanship alive. He trained under Odani Seiichirō Nobutomo (男谷精一郎信友), served as a Kōbusho instructor and later as head of the Yūgekitai, and after the Restoration organized the gekiken-kōgyō (撃剣興行; officially-licensed public fencing exhibitions), the institutional link most relevant to this register’s Meiji-bridge material (Sakakibara Kenkichi (榊原鍵吉), n.d.).

Names and readings

The formal given name (imina) is Tomoyoshi (友善), attested with reading ともよし; the calling name (tsūshō) is Kenkichi (鍵吉) (Sakakibara Kenkichi (榊原鍵吉), n.d.). No azana or gō is attested — the frequently cited “saigo no kenkaku” (最後の剣客) is a byname. The kaimyō in the front matter rests on a single non-reference source and its reading is unverified.¹

Training under Odani; the yawara question

He entered Odani’s Azabu Mamiana (麻布狸穴) dōjō in Tenpō 13 (1842) at thirteen. When Odani urged him to transfer to a nearer major school — Genbukan (玄武館), Shigakukan (士学館), or Renpeikan (練兵館) — he refused, and Odani conferred menkyo kaiden (免許皆伝) on him gratis in Kaei 2 (1849), bearing the costs because of the family’s poverty (Jikishinkage-ryū (直心影流), n.d.). His sword training was Jikishinkage-ryū alone. He did, however, learn Totsuka-ha Yōshin-ryū (戸塚派楊心流) jūjutsu at the same dōjō, taught by the Numazu-han instructors Kashiwazaki Matashirō (柏崎又四郎) and Aizawa Katsuyuki (藍澤勝之). That the Odani dōjō imported jūjutsu instruction rather than transmitting its own is the evidentiary point: it suggests Jikishinkage-ryū itself retained little yawara (柔; grappling) in its curriculum by mid-century — an inference developed in §9.

Fellow disciples

Laterally, through Odani rather than his own dōjō, he sits beside Shimada Toranosuke (島田虎之助; Katsu Kaishū’s sword teacher) (Shimada Toranosuke (島田虎之助), n.d.), Mitsuhashi Torazō (三橋虎蔵), Yokokawa Shichirō (横川七郎), and Amano Hachirō (天野八郎; the Shōgitai leader) (Sakakibara Kenkichi and the bakumatsu kenjutsu circle (Japanese Wikipedia), n.d.).

Kōbusho service and bakumatsu career

Odani recommended him as a founding Kōbusho kenjutsu instructor in Ansei 3 (1856); the academy opened under Odani as tōdori and was abolished in the eleventh month of Keiō 2 (1866), absorbed into the Rikugunsho (陸軍所). The reference dictionaries give his grade as kyōju-kata (教授方) rising to shihan-yaku nami (師範役並) with ryō-goban jōseki (両御番上席) in Genji 1 (1864).[^kobusho] He became Tokugawa Iemochi’s personal fencing instructor and rose to ninomaru rusui-yaku kaku (二ノ丸留守居役格).

He accompanied the shōgun’s Kyoto procession in 1863 (reportedly cutting down Tosa rōnin at Shijō-gawara), was in the Kansai for the Chōshū campaign in 1865, and returned to Edo when Iemochi died at Osaka Castle in the seventh month of Keiō 2 (1866) (Japanese Wikipedia, n.d.). Transferred to Yūgekitai tōdori (遊撃隊頭取) under the military reform, he soon resigned and opened a dōjō at his Shitaya Kurumazaka (下谷車坂) residence (Sakakibara Kenkichi (榊原鍵吉), n.d.). At Ueno in 1868 he did not join the Shōgitai but escorted the Rinnōji-no-miya prince Kōgen (輪王寺宮公現入道親王, later Kitashirakawa-no-miya Yoshihisa) to safety at Mikawajima (三河島), carrying him by turns with the bathhouse-keeper Echizen-ya Sahei (越前屋佐兵衛). He then followed Tokugawa Iesato to Sunpu (later Shizuoka-han), returned to Tokyo in Meiji 3 (1870), and declined the Gyōbushō daikeibu (刑部省大警部) post, recommending his brother Ōsawa Tetsusaburō (大沢鉄三郎) instead.

Teaching

Sakakibara’s time in the early 1860s was spent teaching at the Kōbusho. Sakakibara held no private dōjō during his shogunal-guard years. He accompanied Iemochi to Kyoto in Bunkyū 3 (1863). Sakakibara opened his own dōjō — at Shitaya Kurumazaka (下谷車坂) — in the eleventh month of Keiō 2 (1866), upon resigning when the Kōbusho was reorganized into the Rikugunsho (陸軍所) (Japanese Wikipedia, n.d.).

Before 1866, Sakakibara’s teaching platform was his Kōbusho office (kyōju-kata 教授方, later shihan-yaku 師範役) itself, not a private school. After 1866 he held the dōjō but had left shogunal service now that Iemochi was dead.

The Jikishinkage-ryū private dōjō of that earlier time was not Sakakibara’s but instead Odani Seiichirō’s (男谷精一郎). In Odani’s absences it was run by his shihan-dai (師範代) Honme Yarijirō (本目鑓次郎) — himself a Kōbusho Jikishinkage-ryū kyōju-kata level instructor. Odani’s dōjō was at Azabu Mamiana (麻布狸穴) only from its founding in Bunsei 6 (1823); on his teacher Danno Mahosai’s death he was given Danno’s dōjō at Honjo Kamezawa-chō (本所亀沢町) and moved there in Ansei 5 (1858).

Through the Kōbusho years the Odani dōjō — the Honjo dōjō that Britannica calls the most prestigious of the bakumatsu, producing Shimada Toranosuke, Mitsuhashi Torazō, Yokokawa Shichirō, and Sakakibara — was at Kamezawa-chō. Sakakibara’s school came later.

Gekiken-kōgyō

In Meiji 6 (1873) he founded the officially-licensed gekiken-kōgyō at Asakusa Saemon-gashi (浅草左衛門河岸), backed by the Tokyo governor Ōkubo Ichiō (大久保一翁) and modeled on sumō staging — a board ring, east/west sides, three-bout matches, a referee. It was hugely popular until a glut of imitators drew a Tokyo ban that July (Sakakibara Kenkichi (榊原鍵吉), n.d.).

Kabuto-wari

At the imperial-viewing kabuto-wari (兜割り; helmet-cutting) held in 1886 or 1887 at the Fushimi-no-miya (伏見宮) residence, three men attempted to cut a metal helmet before Emperor Meiji: Hemmi Sōsuke (逸見宗助) and Ueda Umanosuke (上田馬之助), both Shigakukan (士学館) men, failed; Sakakibara cut roughly san-zun go-bu (三寸五分; ≈ 10.6 cm) into the helmet with a Dōtanuki (同田貫) blade (Sakakibara Kenkichi (榊原鍵吉), n.d.; Nakabayashi Shinji (中林信二), n.d.).[^kabuto]

##8. Students, transmission, and succession

The documented inner circle of Sakakibara is small despite the scale of the Kurumazaka dōjō and the gekiken-kōgyō.

Yamada Jirōkichi (山田次朗吉, 1863–1930; art name Ittokusai 一徳斎) is the successor: on New Year’s Day Meiji 27 (1894) Sakakibara conferred menkyo kaiden on him as 15th-generation head and handed over the dōjō, dying that September (Japanese Wikipedia, n.d.). Yamada also trained kata under the Fujikawa-ha (藤川派); a second teacher is variously given as “Yamada Hachirō” (Shimada Hiroshi (島田宏) 1931) or Saitō Akinobu (斎藤鑑信) (Ishigaki Yasuzō (石垣安造), n.d.).

Takeda Sōkaku (武田惣角) is claimed by family tradition as an uchi-deshi, but this is weakly corroborated and his sword work is more plausibly Ono-ha Ittō-ryū (小野派一刀流); recorded here as contested, not attested transmission (Ikezuki Ei 2015; Amdur 2018).[^furi]

By the main-line reckoning Sakakibara is the 14th head, and the line was very likely almost broken at his death — the natural successor would have been Shimada Toranosuke (1810–1864), who predeceased him.[^iwasa] The ordinal is line-specific and should be read against the competing numbering in the register’s Kawashima material rather than treated as absolute.

Jigeiko Focus

His later dōjō was known for sparring — jigeiko and shiai — with only periodic kata practice, as the MFA’s Gekkenka print attests (Museum of Fine Arts, Boston, n.d.).

Jikishinkage-ryū at this time is chiefly a sword art increasingly focused on shiai, with Odani also licensed in Hōzōin-ryū sōjutsu (槍術; spearmanship), Shimada Toranosuke practiced Kitō-ryū jūjutsu, and both Odani and Sakakibara took Totsuka-ha Yōshin-ryū at Danno’s (団野) school.[^namiki]

One line of contemporary practice has an old schedule from Sakakibara’s dōjō, that lists Hōjō practice as occuring once a month.

Death and burial

He died 11 September 1894 (Meiji 27) of kakke shōshin (脚気衝心), kyōnen 65, and was buried at Yotsuya Saiō-ji (四谷西応寺); the grave is a Shinjuku-ku designated historic site — a candidate for on-site inscription work.
