Comparing mokuroku of Maniwa Nen-ryū, Jikishinkage-ryū and Kashima Shin-ryū

↑

Kunii Zen’ya’s training spanned all three streams compared here — the Kunii-house Kashima Shin-ryū and Jikishinkage-ryū as house transmissions, and Maniwa Nen-ryū (with Myōdō-ryū) under Suhara Kuniyasu. Two of them are also among the heihō sandai genryū (兵法三大源流; the three source-streams): the Nen (念) line and the Kage/Shinkage (陰) line from which Jikishinkage-ryū descends. Comparing the three curricula therefore tests two things at once: what material if any Kunii actually synthesized, and whether the modern Kashima Shin-ryū curriculum carries Jikishinkage-ryū or Nen-ryū structural features — which bears directly on the transmission-direction argument (influence flowing into a reconstructed Kashima Shin-ryū from the better-documented schools, rather than out of an ancient Kashima font).

1. Jikishinkage-ryū (直心影流)

Source: Karukome 2013 dissertation and the Nihon Kobudō Kyōkai entry. The koto cluster and the jū-no-kata “龍尾→曲尺” were added by Naganuma Kunisato (see the densho-tables file).

• Hōjō (法定) — 4 principal forms, hardwood bokutō (straight tō): Ittō-ryōdan (一刀両断), Uten-saten (右転左転), Chōtan-ichimi (長短一味), Hassō-happa (八相発破). Their ura is the Habiki (刃挽), performed with a live blade.
• Jū-no-kata (十之形) — the basic shinai-uchikomi set, enumerated as 14 items under 7 named forms: Ryūbi (龍尾), Omokage (面影), Teppa-shintai (鉄破進退)〔reading tentative〕, Matsukaze (松風), Hayafune (早船), Kanejaku (曲尺), Enren-tōren-tairen (圓連刀連体連)〔tentative〕. Four are 左/右 pairs, Teppa-shintai is one form of four items, and the last two are independent (see the jū-no-kata composition file).
• Tō-no-kata (韜之形) — 14 forms, fukuro-shinai.
• Kodachi (小太刀) — 6 short-sword forms.

2. Kashima Shin-ryū (鹿島神流)

Source: the school’s own site (kashima-shinryu.jp), the Inaba Minoru / BAB instructional material, and the school’s Wikipedia entry. Transmitted as Kunii-sōke / Seki-shihanke in current times.

• Principle sets: go-ka no hōjō (五ヶ之法定; five unities — 動静一体・起発一体・攻防一体・虚実一体・陰陽一体) and the physical base hō-en-kyoku-choku-ei (方円曲直鋭).
• Ichi-no-tachi (一之太刀) — the kesa-giri (袈裟斬) cut attributed to Matsumoto Bizen no Kami.
• Kihon-dachi (基本太刀) — 5 forms, bokutō: Kesa-giri (袈裟斬), Ashibarai-ukifune (足払浮舟), Kiriwari (斬割), Waritsuki (割突), Kurai-dachi (位太刀).
• Ura-dachi (裏太刀) — 10 forms, fukuro-shinai: Men-dachi-zuke (面太刀付), Kesa-dachi-zuke (袈裟太刀付), Sokui-dachi (続飯太刀), Gedan-kote-dome (下段籠手止), Kyo-dachi-kote-giri (虚太刀籠手斬), Sokui-zuke (続飯付), Mikiri-ken-chūtai (見切剣中体)〔reading tentative〕, Chokutai-chūken (直体中剣)〔tentative〕, Kesa-giri-sodezuri (袈裟斬袖摺), Enpi-ken (燕飛剣).
• Musōken (無想剣) — attributed to the 12th shihanke, Kunii Daizen Minamoto no Kuriyama (國井大善源栗山).
• Jūjutsu — reiki-no-hō (霊気之法), with居捕・立業・投業・組業 groupings and an extensive named-technique inventory (e.g. kata-mune-dori 片胸捕, kiri-otoshi 切落, tsubame-gaeshi 燕返, sakui-zuke 続飯付, karate-kenpō-yaburi 唐手拳法破).
• Other arms: battō (祓太刀 harai-tachi), naginata, kaiken, jō, yari, bō.
• Implements: bokutō for kihon-dachi, fukuro-shinai from ura-dachi onward.

3. Maniwa Nen-ryū (馬庭念流)

Source: the Nen-ryū sōke site (nen-ryu.jp), the Takasaki City cultural-property listing, and Ozawa 1971. Registered with the Kobudō Shinkōkai simply as “Nen-ryū”; “Maniwa” is the customary name.

• Omote go-hon (表五本) — 5 forms, bokutō: Jōryaku (上畧), Geryaku (下畧), Chūryaku (中畧), Mugamae (無構), Gasshō (合掌).
• Ura san-bon (裏三本) — 3 forms, fukuro-shinai: Kiriokuri (切送), Jōdan-giri / Jōdan-uchikomi (上段切／上段打込), Sandan-giri (三段切).
• Kumi jippon (組十本 / 裏五本) — 10 forms, live blade. Sono ichi: Uchikomi-ranshō (打込乱勝)〔tentative〕, Sakairi (逆入)〔tentative〕, Byōbu-gaeshi (屏風反), Tachi-sabaki (太刀捌), Gasshō-kuzushi (合掌崩). Sono ni: Shishi-hōge (獅子峰下)〔tentative〕, Nakazumi (中墨), Chūō-ōzume (中央大詰)〔tentative〕, Sumi-iri (澄入)〔tentative〕, Shishi-funjin (獅子奮迅).
• Naginata go-hon (長刀五本), Yari go-hon (槍五本).
• Yadome-jutsu (矢留術) — headmaster (or top licensee) only.
• Supplementary: tsuke-tachi-no-koto (附太刀之事, 5) and te-no-uchi-no-koto (手之裡之事, 9).
• Implements: bokutō for omote; self-made head-protector and cloth kote with fukuro-shinai for uchikomi.

4. Structural comparison

Tier	Jikishinkage-ryū	Kashima Shin-ryū	Maniwa Nen-ryū
Foundational set (bokutō)	Hōjō (4)	Kihon-dachi (5)	Omote go-hon (5)
Applied set (fukuro-shinai)	Tō-no-kata (14)	Ura-dachi (10)	Ura san-bon (3)
Inner / live-blade or secret	Habiki (live blade); kodachi (6)	Musōken; ichi-no-tachi	Kumi jippon (shinken, 10)
Long arms	— (sword school)	naginata, yari, bō	naginata (5), yari (5)
Unarmed	—	jūjutsu (reiki-no-hō) + large inventory	—
Sparring tradition	fukuro-shinai → later shinai/bōgu (kendo ancestor)	fukuro-shinai (ura-dachi onward)	fukuro-shinai with self-made headgear

The shared architecture is a bokutō foundational set → fukuro-shinai applied set progression, present in all three. That progression is real but weak as evidence of specific descent: it is the general Edo-period two-implement pattern, and all three schools sit in or beside the Shinkage / Nen orbit where it was common.

5. What the overlaps do and do not show

Suggestive, school-specific overlaps (Kashima Shin-ryū ↔ Jikishinkage-ryū). The Kashima Shin-ryū sword sets carry several terms that cluster in the Shinkage / Jikishinkage stratum rather than the Nen stratum: enpi (燕飛, KSR ura-dachi #10 Enpi-ken) is the signature Shinkage form-name — Kamiizumi’s Enbi / the Kage-ryū Sarutobi lineage that heads the Shinkage sangaku; kiri-otoshi (切落), which appears in the KSR jūjutsu inventory, is one of the four koto Naganuma Kunisato added to Jikishinkage-ryū in 1764; sokui (続飯, KSR ura-dachi #3 and #6) and kesa (袈裟, KSR ichi-no-tachi and kihon #1) likewise sit in the Shinkage-derived vocabulary. This is consistent with — though it does not by itself prove — Jikishinkage-ryū vocabulary having flowed into the Kunii-house curriculum, the direction the ōyō shinri argument already points to.

Weak or non-probative resemblances. Generic posture/structure names (上段/下段/中段, left-right pairings, “three-step” cuts) recur across all three and across most kenjutsu and carry no descent information. The shared gasshō (合掌) between Nen-ryū’s omote and its kumi is internal to Nen-ryū and has no Kashima/Jiki echo. The bokutō→fukuro-shinai tiering, as noted, is a period-wide pattern.

Kashima Shin-ryū uses Maniwa Nen-ryū styled fukuro shinai, not those favored by Jikishinkage-ryū.¹

The controlling caveat. Kashima Shin-ryū as a transmitted curriculum appears to be a twentieth-century reconstruction by Kunii Zen’ya, who had himself trained in Jikishinkage-ryū and Maniwa Nen-ryū. Any resemblance between the modern Kashima Shin-ryū syllabus and those two schools is therefore at least as well explained by Kunii’s own eclectic training as by an ancient common Kashima source — and the documentary record (no 鹿島神伝 colophon or Matsumoto founder before Naganuma, 1764; no mention of Kunii, Seki or Motooka in Karukome’s academic study) gives no independent footing for the older-source reading. So the kata overlaps are best presented as corroborating the inward-flow hypothesis, not as evidence of Kashima priority. They are checkable auxiliary claims, and they fail in the direction that degrades the antiquity argument rather than supporting it.
