The Kōbusho [講武所]

講武所

Topic map →

A description of the late Tokugawa Kōbusho martial academy, its teachers, levels and related styles.

One caution is in the aliasing of Japanese surnames: several prominent figures have the same surname but are very different people. This is compounded by the fact that figures will be sometimes referenced by their adult name, child name, or sword/art name.

☰ Introduction

The Kōbusho ran roughly a decade. Preparations began in 1854 (Ansei 1) under the rōjū Abe Masahiro after Perry, starting with a small drill ground and a facility called the Kōbujō (講武場); it was formally opened as the Kōbusho in the 4th month of 1856 (Ansei 3) at Tsukiji Teppōzu, with master-instructors and kyōju-kata appointed in swordsmanship, spearmanship and gunnery, and with archery, jūjutsu and swimming also taught. Kōbusho trainees were selected from skilled martial artists drawn from the hatamoto, gokenin, and the domains.

Yamaoka Tesshū (山岡鉄舟; NDL portrait (opens in a new tab)), later the founder of Ittō Shōden Mutō-ryū, was among those involved in the academy’s instantiation — hired as a supervising instructor of swordsmanship (kenjutsu sewa-yaku, 剣術世話役) in 1856.

The founding plan is preserved in the kokoroe-kata taii (心得方大意; “outline of guiding principles”) that the Kōbujō sōsai submitted to the rōjū for approval, quoted at length in this record (東京市史外編, 講武所, pp. 33–35). It set the institution’s ethos as jitsui no shugyō daiichi (実意之修業第一; “substance in training first, over outward ornament”) and, notably, prescribed free contest practice (試合稽古) with no fixed kata for sword and spear — students of any ryūha bouting together. It also split the enterprise by site: the cramped Yotsuya/Kuichigai-soto ground was assigned to spear, sword and jūjutsu (槍剣柔術); Tsukiji to gunnery, military science, cavalry and swimming (砲術・兵学・軍馬・水練); and Etchūjima to artillery and mass drill (大筒・人数調練).

The school moved to a new, consolidated site at Kanda Ogawamachi in 1860 (Man’en 1). Then the military-reform pressure toward a Western-style army hollowed out the classical side: archery and jūjutsu instruction were dropped in 1862 (Bunkyū 2), and in the 11th month of 1866 (Keiō 2) it was renamed the Rikugunsho (陸軍所), thereafter concentrating on gunnery.

Its final dissolution came in the 6th month of 1867 (Keiō 3), when a three-arms officer school was established within the Rikugunsho and the Kōbusho ceased to exist in name and substance.

Below we describe the school’s organization, initial instructor cadre, the traditions practiced by its teachers, and what military units instructors and students participated in after it closed.

☰ Kōbusho Levels

Regarding levels, the Kōbusho itself did not confer ryūha ranks. The Kōbusho offered instead institutional advancement up its own appointment ladder — closer to an academic-rank progression than to either a school license or a diploma. Below the directors (sōsai) and the overall head (tōdori, Odani), each discipline was staffed by a body of kyōju-kata; at the 1856 opening the striking arts were organized as kyōju-kata under a discipline head rather than under a single named master-instructor. The formal titles shihan-yaku (師範役; head instructor) and shihan-yaku-nami (師範役並; associate) were regularized only later, in the 5th month of 1861 (Bunkyū 1), after which a discipline could carry more than one — a shihan-yaku with one or more nami — over the kyōju-kata beneath them.

Shugyōnin (修業人 / 修行人) who distinguished themselves in the cross-school bouting the Kōbusho fostered could be promoted to assistant grades — sewa-kokoroe (世話心得; administrative care guidelines), sewa-yaku (世話役; administrative liaison role), then kyōju-kata shutsuyaku (教授方出役; instructor dispatch role) and ultimately kyōju-kata. These were bakufu offices carrying stipends and status (Sakakibara’s kyōju-kata post came with 100 hyō and a 10-man allowance, and he later rose to shihan-yaku), awarded on demonstrated merit. That appointment ladder — not a paper credential — was the recognition.

Grade tracked bakufu status as much as skill. The founding charter (東京市史外編, 講武所, pp. 14–15) reserved the shihan-yaku title for distinguished men drawn from the direct bannermen (御旗本; o-hatamoto) — roughly twenty per art, serving in pairs at two sites about six days a month — while men of audience-rank and below, sub-vassals and rōnin (御目見以下・陪臣・浪人) of note were styled kyōju-kata, roughly ten per art; jūjutsu specifically was to draw ten bannermen and ten from the lower pool. The trainee body (稽古人・修行人) was broader still, open to yoriai, the guard corps, minor officials, kobushin, eldest sons and younger sons and dependents, and gokenin-rank group members, with sub-vassals admitted subject to review and men over fifty excused from fixed-day practice but permitted to supervise. The practical consequence recurs below in the jūjutsu division: a baishin (陪臣; sub-vassal), however skilled, could rise only to kyōju-kata, not to the bannerman-only shihan-yaku title.

Ryūha identity was not dissolved by the institution. The specialist scholarship still catalogs Kōbusho personnel explicitly by school — for instance, the study of Toda Hachirōzaemon’s diary listing the kyōju-kata, sewa-kokoroe and trainees with their ryūha (武道学研究 14(2), 1982). So a man was simultaneously “a Jikishinkage-ryū menkyo holder” (his school’s certification) and “a Kōbusho kyōju-kata” or “a Kōbusho sewa-yaku” (his institutional office), and those two were tracked independently.

Military Service

Many of its instructors and former students were recruited into late Tokugawa elite units such as the Yūgekitai, Seieitai, and Shōgitai.

☰ Kenjutsu Cadre 剣術

The opening roster of 1856 appointments to the academy instructor cadre are recorded in the Wakadoshiyori Mōshiwatashi (若年寄申渡), in “Ansei 3 Gosho-tsukemen 7” (安政三年御書付面 七), held in the 東京大学 史料編纂所 (Historiographical Institute, University of Tokyo) database. There were eleven initial kenjutsu kyōju-kata (剣術教授方; swordsmanship instruction role), with Odani Seiichirō of Jikishinkage-ryū as tōdori (頭取; head or chief):

• Toda Hachirōzaemon of Tamiya-ryū
• Matsushita Seiichirō, Iba Sōtarō, and Mitsuhashi Torazō of Shingyōtō-ryū
• Sakakibara Kenkichi and Honme Yarijirō of Jikishinkage-ryū
• Fujita Taiichirō of Shintō Munen-ryū
• Matsudaira Chikaranosuke of Ryūgō-ryū
• Kondō Yanosuke of Ittō Chūya-ryū
• Inoue Hachirō of Hokushin Ittō-ryū
• Imahori Chiiozō of Shinkage-ryū

The 4th Momoi Shunzō was added as a kenjutsu kyōju-kata shutsuyaku from 1863.

This same eleven-name roster is reproduced in the present record (東京市史外編, 講武所, p. 33), which confirms Odani as tōdori. By the time of Iemochi’s 1862 (Bunkyū 2) visit its reward list shows the senior line settled as Odani Seiichirō (男谷精一郎) as kenjutsu shihan-yaku, with Toda Hachirōzaemon (戸田八郎左衛門) and Iba Gunbei (伊庭軍兵衛) as shihan-yaku-nami (師範役並) — the later Iba appointee, distinct from the 1856 kyōju-kata Iba Sōtarō of the same Shingyōtō-ryū house.

☰ Sōjutsu Cadre 槍術

There were ten initial Kōbusho sōjutsu (spear) instructors in 1856. The department was led by Takahashi Deishū of Jitokuin-ryū — also transmitted as Ninshin-ryū (忍心流), the Yamaoka-family spear — who became shihan-yaku in 1860 (Man’en 1) and in Keiō 2 (1866) held the post of sōjutsu kyōju-tōdori (槍術教授頭取; director of instruction) while leading the Yūgekitai. His birth-name Takahashi Kenzaburō (高橋謙三郎), and later court title Ise-no-kami with the imina Masaaki (政晃), are how he appears in the academy rosters.

Beside Deishū, the record’s 1862 senior spear line (東京市史外編, 講武所, pp. 132–133) names Katō Heikurō (加藤平九郎) as shihan-yaku and Andō Sōbei (安藤惣兵衛) as shihan-yaku-nami. The kyōju-kata and sewa-kokoroe tier includes Hiraiwa Jirodayū (平岩次郎太夫) — the spear teacher lampooned as “the Akasaka fellow” in a contemporary rakushu (p. 48) — with Komai Hangorō (駒井半五郎) and Yoshida Katsunosuke (吉田勝之助) among the Ansei-period roster. Noguchi Takehiko’s Bakufu Hoheitai (幕府歩兵隊) adds Komai Shizuma, Katsu Yohachirō, Nagao Kōhei and Naoe Kitaemon to the department; the two Komai point to a single hereditary spear house rather than unrelated men, and those four names await confirmation of their kanji and readings against a primary roster. Apart from Deishū’s Jitokuin-ryū, this record does not give the spearmen’s individual ryūha; those remain to be established from the bukan (武鑑) and domain bungenchō (分限帳).

Several of the Kōbusho members also were licensed in the Hōzōin-ryū of sōjutsu, famous for its crescent moon kama-yari. Other important sōjutsu approaches favored by the Tokugawa houses included the Kan-ryū kudayari (管槍; tube-spear) of Owari and the 3.6m suyari (素槍; plain spear) Ōshima-ryū of Kii and Kishū.

Beyond the Tokugawa houses, spear ryūha that mattered nationally were Saburi-ryū (佐分利流, a kagiyari/hook-spear line), Fūden-ryū (風傳流) and Taneda-ryū (種田流, another kudayari school). Of these, Kan, Saburi, Fūden and Hōzōin Takada-ha are the four approaches that survived into present day practice.

☰ Heigaku Cadre 兵学

Kubota Sugane (窪田清音; tsūshō Gendayū 源太夫) was a Kōbusho tōdori who held the shihan-yaku post in heigaku (兵学; military science) rather than in a weapons department, on the strength of the Yamaga-ryū (山鹿流) strategy he headed. This record catalogs his full art-set (東京市史外編, 講武所, pp. 204–205) as Tamiya-ryū kenjutsu (田宮流剣術), Muhen-mukyoku-ryū sōjutsu (無辺無極流槍術), Nakajima-ryū gunnery (中島流砲術) and Sekiguchi-ryū jūjutsu (関口流柔術) — the last a jūjutsu line held as a subordinate art — so it is unclear whether he taught any of them at the academy alongside his strategy and tactics. Note that the record gives his spear line as Muhen-mukyoku-ryū, not the Hōzōin-ryū attributed to him in some earlier accounts, and that he is a different man from the jūjutsu teacher Kubota Shigekatsu (窪田鎮勝) below.

☰ Jūjutsu Cadre 柔術

Jūjutsu was not part of the original 1856 curriculum; it and archery were added only after the move to Ogawamachi, entering the syllabus around 1860 (Man’en 1) on the reasoning — recorded with some ambivalence in this source — that a bare-handed art had until then been thought unsuited to the battlefield beside the sword, spear and gun.

The documented roster of the division (東京市史外編, 講武所, pp. 92–95, drawing on the Taisei Bukan 大成武鑑 and Fujiokaya Nikki 藤岡屋日記) records:

• shihan-yaku (師範役; head instructor): Suzuki Seibei (鈴木清兵衛) of Kitō-ryū, of ryōban-kaku (両番格) rank;
• shihan-yaku-nami (師範役並; associate head instructor): Katayama Yajirō (片山彌次郎) of the Shin-ban (新番);
• kyōju-kata tōdori (教授方頭取; head of instructors): Totsuka Hikosuke Hidetoshi of Totsuka-ha Yōshin-ryū (戸塚派楊心流), a retainer of the Numazu-han Mizuno house;
• jūjutsu-kata kyōju-kata (柔術形教授方; kata instructor): Ōkubo Kyūtarō (大久保久太郎), of the Shoin-ban (書院番);
• sewa-kokoroe (世話心得; assistant): Murayama Eizō (村山栄蔵), of the Shin-ban;¹
• randori sewa-kokoroe (乱取世話心得; free-sparring assistant): Chūjō Kinnosuke (中條金之助), of the Shoin-ban — concurrently a kenjutsu kyōju-kata, a cross-appointment grounded in his own Totsuka-ha Yōshin-ryū mokuroku (目録);
• shugyōnin (修行人; trainee): Katō Seiichirō (加藤精一郎), of the Ō-ban (大番).

The division is a clean illustration of the status rule set out above. Totsuka, by common account the strongest jūjutsuka of the group, was a baishin (陪臣; sub-vassal of the Numazu Mizuno house) and so ineligible for the bannerman-only shihan-yaku title; he sat instead at the head of the kyōju-kata tier, while the direct bannermen Suzuki and Katayama held the shihan-yaku posts.²

Three further figures are placed in the division by other sources but do not appear in this record’s roster: Fukuda Hachinosuke (福田八之助) of Tenjin Shin’yō-ryū, and Motoyama Shōō (本山正翁) and Iikubo Tsunetoshi (飯久保恒年) of Kitō-ryū — the latter two usually placed at the Kōbusho on the strength of Kanō Jigorō’s account of his own teachers.³

Matsuoka Katsunosuke, a Kuroda-han baishin sent as a shugyōnin, who had first practiced Tenjin Shin’yō-ryū, likewise does not appear in this jikisan-focused roster, consistent with his sub-vassal status; his own biography records him rising to a junior jūjutsu assistant grade.⁴

Jūjutsu instruction ran from about 1860 (Man’en 1) to 1862 (Bunkyū 2). On the sixth of the tenth month of 1862 the division was abolished: the shihan-yaku Katayama and Suzuki were reassigned to the two guard corps, and Totsuka received a gratuity of thirty silver pieces and two jifuku (時服). This record gives no account of the reasoning behind the closure — unlike archery, whose master petitioned twice for revival — though later school histories attribute it to the injuries, and reportedly deaths, sustained in the division’s randori.
