Source Register

Below you will find a consolidated, annotated register of the primary documents and secondary scholarship cited across this site. Please also consult the glossary for a list of terms and their definitions. Some information on the research methods and conventions is also available.

Source Register

Each entry below carries a short note on its provenance and evidentiary weight; primary manuscripts list their archive, shelfmark and access state. “Cited in” links each source back to the pages that use it. The register is generated at build time from a single bibliography, so it stays in step with the essays.

On independence. The author’s own writing is not independent corroboration of itself: neither innerdharma.org (this site) nor jikishinkageryu.org (opens in a new tab) counts as a corroborating source. Tradition-internal lineage tabulations (house dōtō lists and the like) are corroborative of formal names but are not independent of the line, and are marked as such.

Primary sources

Classical manuscripts and archival documents, with archive and shelfmark where held.

Chéng Zōngyóu (程宗猷; 1561–1636). 1621. “Gēngyú shèngjì (耕餘剩技; Skills Beyond Farming).” Manuscript.
Huáng Zōngxī (黃宗羲). 1669. “Wáng Zhēngnán mùzhìmíng (王征南墓誌銘; Epitaph for Wang Zhengnan).” Manuscript.
Nakano Nariaki. 1710. “Taisha-ryū kaichū (タイ捨流解紐).” Saga Prefectural Library (main building), Nabeshima-ke Bunko (reproduction; original deposited by the Nabeshima Hōkōkai). 複鍋/353-1 · 複製史料 (reproduction copy), in-library use only (禁帯出), open stacks (新庫3層), item code 210018230; on shelf. No digitization or published transcription located; photocopy of the reproduction obtainable on request.. Hizen Taisha-ryū densho dated Hōei 7 (1710), attributed to a Nabeshima retainer and grand-pupil of Kijima Keiemon, written to record the line’s oral transmission as a plain exposition; an internally-attested house text—evidence for the Hizen line’s self-understanding, not external corroboration of the school’s origins.
Hinatsu Shigetaka. 1716. Honchō bugei shōden (本朝武芸小伝). Multiple holdings (e.g. Naikaku Bunko; Tōhoku Univ. Kanō Collection). 〔edition-specific〕 · Digitized (National Archives of Japan / NIJL). Completed Shōtoku 4 (1714), published Kyōhō 1 (1716) in Kyoto; the oldest Japanese martial biographical compilation and the conduit by which the Dewa-origin Hayashizaki account became received tradition, though not contemporary with the events and shadowed by a competing Sagami-origin version (modern editions: Dai Nippon Butokukai 1920; an enlarged annotated edition with a Wataya postscript).
Dài Lóngbāng (戴龍邦). 1750. “Liùhé quán xù (六合拳序; Preface to the Six-Harmonies Fist Manual).” Manuscript.

Primary literary source for the Haguro–Gassan–Yudono verses and the Gassan-smith passage, in Hagiwara Yasuo’s standard annotated Iwanami Bunko edition (text of 1689–1702).

Jōshin hosshinnō. n.d. “Shō-ichi-i Haguro Sansho Dai-gongen (正一位羽黒三所大権現).” n.d. Dewa Sanzan History Museum (出羽三山歴史博物館), Hagurosan. accession number not recorded · on display; photographed in situ, 2026. Brushed by the Tendai zasu Jōshin (Kajii-no-miya), making the apex-rank gongen titulature of the Tendai-aligned Haguro pole an authoritative internal witness; the reading of 承真 as Jōshin is conventional but not furigana-confirmed.
Jōshin hosshinnō. n.d. “Namu Shōken Daibosatsu (南無照見大菩薩).” n.d. Dewa Sanzan History Museum (出羽三山歴史博物館), Hagurosan. accession number not recorded · on display; photographed in situ, 2026. Authoritative as a Tendai-zasu autograph, but the bodhisattva-title 照見大菩薩 has no confirmed referent within the Dewa Sanzan pantheon and is left unidentified.
Author unknown. n.d. Kōbō Daishi sonzō (弘法大師尊像). Dewa Sanzan History Museum (出羽三山歴史博物館), Hagurosan. accession number not recorded · on display; photographed in situ, 2026. Yudonosan Shingon-line founder-icon embodying the Kūkai-foundation tradition against the Hachiko-no-Ōji foundation of the Tendai Haguro side; undated and unattributed on the museum label.
Dainichi-ji. n.d. Sanzan honji surimono (三山本地刷物). Dewa Sanzan History Museum (出羽三山歴史博物館), Hagurosan. accession number not recorded · on display; photographed in situ, 2026. The issuing temple Dainichi-ji styles itself 正別當 (principal bettō), a claim that competes with Hondōji’s standard designation as principal and Dainichibō’s 総本寺 claim, making the colophon a partisan witness; no textual parallel for the geju could be located.
Author unknown. n.d. Tengu-kyō (天狗経). Nihon Daizōkyō, Shugendō shōsho subcollection. NDL Digital Collections (login-gated for the relevant volumes); modern reprint via Kokusho Kankōkai 2000. Late, apocryphal mikkyō invocatory text of loose transmission whose widely reproduced forty-eight-tengu list (incl. Hagurosan Konkōbō) circulates via Edo woodblock prints and is not an independent witness to any liturgical recension.
Qī Jìguāng. 〔1560s; rev. c. 1584〕. Jìxiào xīnshū (紀效新書). Ming military manual whose long-sword section reproduces a fragment of a Kage-ryū catalogue (影流之目録, with stance figures and cursive Japanese) captured from wakō, later carried into Mao Yuanyi’s Wǔbèizhì (武備志, 1621) and reintroduced to Japan via Matsushita Kenrin’s Ishō Nihon-den (異称日本伝, 1688); the earliest external witness to Kage-ryū technique nomenclature.
Kiyokawa Hachirō. 〔1855; modern ed. Iwanami Bunko, 1969〕. Saiyūsō (西遊草). Travel diary by the Shōnai-born bakumatsu activist Kiyokawa Hachirō; records the "Nobukuni" long-sword and swordsmen worshipping at the Hayashizaki shrine, an independent contemporary witness to the iai votive network.
Kumano-Iai Ryō-Jinja (shrine history). 〔n.d.; shrine self-account〕. “Kumano-Iai Ryō-Jinja yuisho / engi (熊野居合両神社由緒; shrine history).” 〔n.d.; shrine self-account〕. Kumano-Iai Ryō-Jinja (熊野居合両神社), Hayashizaki, Murayama, Yamagata. 〔n/a〕 · Public. Self-history of the Murayama founder-shrine (popularly Hayashizaki Iai Jinja 林崎居合神社), giving the Kumano Gongen rock-cave origin, the relocation and re-styling as Kumano/Hayashizaki Myōjin, and the 1877 merger-registration as Kumano-Iai Ryō-Jinja; the 1877 date is well attested, the 807/Sekijōgatake foundation is not independently corroborated.

Secondary scholarship

Modern scholarship, reference works and tabulations.

Dainichibō. n.d. Dainichibō kōshiki saito (湯殿山総本寺瀧水寺大日坊 公式サイト). Institutional self-description that itself claims 総本寺/本山 status, hence a partisan witness in the very inter-temple primacy contest it documents.
Dewa Sanzan Jinja. n.d. Dewa Sanzan Jinja kōshiki hōmupēji (出羽三山神社 公式ホームページ). Institutional self-description, reliable for current enshrinement and the shrine’s own doctrinal framing but partisan on contested founding and lineage questions.

Academic treatment of medieval tengu image-formation; useful on the Tengu-kyō as an Edo construct. Publication year unverified.
Pranin, Stanley. n.d. Saigō Tanomo and Takeda Sokaku. Aiki News / Aikido Journal, various issues. Documents the Saigō Tanomo–Takeda Sokaku claim; note Saigō Tanomo is now believed not to have practiced budō.
Reichsarchiv. n.d. Arisugawa-no-miya-ke (有栖川宮家). Amateur compiled genealogy of degraded authority; the 1787–1841 dates should be verified against imperial-house genealogical records before publication.
Hagurosan Kōtaku-ji Shōzenin. n.d. Hagurosan Kōtaku-ji Shōzenin kōshiki saito (羽黒山荒澤寺正善院 公式サイト). Institutional self-description, reliable for the temple’s current status and its own engi but partisan on contested founding questions.

Togawa Anshō. n.d. Dewa Sanzan to Tōhoku Shugen no kenkyū (出羽三山と東北修験の研究). Scholarly study whose full imprint (publisher, year) is unverified and should be confirmed via CiNii NCID BA52222927 before citing.
Web Hiden. n.d. Okuyama Ryūhō (shodai) (奥山龍峰(初代)). Martial-arts media profile; useful for Okuyama’s lineage and Yamagata origin, partisan toward the school it documents.
Hakkō ichiu (八紘一宇). n.d. Japanese Wikipedia. Orientation on the slogan’s 1903 coinage by Tanaka Chigaku and its wartime adoption; corroborate against print scholarship before citing in print.
Wikipedia contributors. n.d. Akiba Gongen (秋葉権現). Encyclopedic tertiary source, basis for distinguishing Akiba Sanjakubō (Echigo Zaōdō origin) from Hagurosan Sankōbō.
Wikipedia contributors. n.d. Dainichibō (大日坊). Encyclopedic tertiary source corroborating the four Yudonosan Shingon bettō-ji and the Kūkai-versus-Hachiko founding split, but not independent of the temples’ own accounts.
Wikipedia contributors. n.d. Daitengu (大天狗). Encyclopedic tertiary source whose 48-tengu list should be checked against a textual edition rather than treated as canonical.
Wikipedia contributors. n.d. Dewa Sanzan (出羽三山). Encyclopedic tertiary source useful for orientation and for its own cited authorities (e.g. Togawa 1973) but not itself independent corroboration.
Wikipedia contributors. n.d. Haguro Gongen (羽黒権現). Encyclopedic tertiary source; useful for the founder-identification chronology but to be checked against the engi texts it summarizes.
Wikipedia contributors. n.d. Hakkō-ryū Jūjutsu (八光流柔術). Encyclopedic tertiary source; adequate for the single-seminar fact, which corrects the "student of Okuyama" characterization.
Wikipedia contributors. n.d. Kōtaku-ji (荒沢寺). Encyclopedic tertiary source corroborating the postwar institutional facts, not independent of the temple’s own account.
Wikipedia contributors. n.d. Saigō Tanomo (西郷頼母). Encyclopedic tertiary source; the oshikiuchi-to-Daitō-ryū transmission it reports is a contested popular tradition, not independent corroboration.
Wikipedia contributors. n.d. Tendai zasu (天台座主). Encyclopedic tertiary list of abbatial incumbencies, adequate for establishing repeated tenure but not fine dates.

Regional press, not peer-reviewed, and the Denrinbō biography within it rests on Taisha-ryū house tradition rather than external corroboration.

Chigiri Kōsai. 2004. Tengu no kenkyū (天狗の研究). Hara Shobō (原書房). The foundational compilation of tengu lore, systematizing the eight great tengu (hattengu) of the sacred mountains; a folklorist’s work, now dated and uncritical in places, so use for the classification rather than for historicity. Originally Dairiku Shobō, 1975.
Fujiwara Akira. 2004. Nihon no gisho (日本の偽書). Bunshun Shinsho 379. Bungei Shunjū (文藝春秋). By an independent (zaiya) researcher working to scholarly standards; establishes the "modern fabricated national history" reading and the prewar ultranationalist linkage, but treats the Kuki document only in passing among the major modern forgeries. Reprinted by Kawade Bunko, 2019 (ISBN 9784309416847).
Hisano Toshihiko, and Tokieda Tsutomu, eds. 2004. Gimonjo-gaku nyūmon (偽文書学入門). Kashiwa Gakujutsu Library. Kashiwa Shobō (柏書房). Academic edited volume (opening with Amino Yoshihiko) on forged documents; Fujiwara Akira’s closing chapter supplies the scholarly framework treating the modern koshi-koden as "modern fabricated national histories," the category to which the Kuki document belongs—methodological grounding rather than a dedicated Kuki-document study.

Standard academic study of the Kumano bettō house and the governing organization of the Kumano Sanzan, awarded the 2007 Nihon Sangaku Shugen Gakkai prize; grounds the genuine Kumano-bettō context against which the ryūha’s founder story is set, but treats the historical bettō lineage and lends no support to any martial transmission.

English practitioner account reproducing dai-tengu from koryū densho (Yagyū, Taisha-ryū and related material); conflates Tengu-shō kata material with the Kashima/Katori complex, so its tengu-kata attributions need checking against primary densho before use.

Conference abstract, 48th Annual Conference of the Japanese Academy of Budo (2015), by kyūdō historians Matsuo (International Budo University) and Goga (Tsukuba); strongest academic source on Kawashima to date. From Sakai Hikotarō’s disciple register, confirms Kawashima as a Heki-ryū Sekka-ha (雪荷派) disciple holding a 指南免許 and the first Tainan enrollee — resolving the Sekka-ha/Chikurin-ha conflict against the 1939 Asahi’s 竹林派. Also: crossed to Taiwan as a kendō teacher, taught kendō/jūdō at the police normal school, opened the 覚眞館 kyūdō dōjō in 1931; a surviving furibō (振り棒; Jikishinkage-ryū) group photo held by Kawashima Katsuko places JSKR kenjutsu at the first Tainan Butokuden.

Sasamori Junzō. 〔unverified〕. 〔Shin-musō Hayashizaki-ryū kata transmission (Sasamori / Tsugaru line) — specific publication to identify〕. Source for the documented Hayashizaki form-set (Omote Mukaemi, Migimi, Hidarimi, Sotomono, etc.), corroborated by the Nihon Kobudō body; the names are positional/enumerative, confirming the absence of tengu-named kata. Sasamori Junzō’s principal published work is the Ittō-ryū gokui; the exact Hayashizaki-iai title needs identifying.
Onozaki Norio. 〔year unverified〕. Shōnai-han no bujutsu: tsuke Matsuyama-han no bujutsu (庄内藩の武術 : 附松山藩の武術). 〔Publisher unverified — small/private press, ISBN-prefix 4-907161〕. Compiled by the kyūdō historian Onozaki Norio (b. 1940) from the Chidōkan academy and the Sakata/Tsuruoka archives; the anchor for the Shōnai domain curriculum (kenjutsu incl. Jikishinkage-ryū and Shinshin Yagyū-ryū; iai Tamiya-ryū and Kage-ryū written 景流, distinct from Aisu’s 陰流).
