On Tengu, Precedence, and Densho

I spent time querying Claude Opus 4.7 on the waterfall I encountered at Kuramadera that was next to a place Kiichi Hōgen was said to have gone on retreat. Kiichi is revered as a possible tutor to Yoshitsune — in drama represented often by the Tengu lord Sōjōbō. I dive through a bit of Kurama area history and then turn towards an analysis, based on Japanese language sources, of the Tengu names found in the Yagyū Shinkage-Ryū Tengushō.

Kyō Hachi-ryū

The Kyō Hachi-ryū (京八流), "Eight Schools of the Capital," is a semi-legendary grouping rather than a historically documented set of ryūha. According to tradition, they descend from teachings given at Kurama-dera (鞍馬寺), in the mountains north of Kyoto, in the late Heian period — roughly the late 12th century. The reputed progenitor is Kiichi Hōgen (鬼一法眼), who is said to have taught the way of the sword to eight Buddhist monks on Mt. Kurama, and the school is said to be the origins of all swordsmanship. Kiichi Hōgen is variously described as an onmyōji or a warrior-monk, and the legend is famously entangled with Minamoto no Yoshitsune's training as Ushiwakamaru — the "tengu" of Kurama are often rationalized as Kiichi Hōgen and his disciples.

The names of the eight schools are not reliably preserved. It does not go beyond being a legendary school of swordsmanship and there are doubts as to whether it actually existed. Even Edo-period budōka regarded the Kyō ryū as largely mythic. Different sources give different lists, and several traditions retroactively claimed Kyō Hachi lineage for prestige. The schools most often named as descendants (not as the original eight, but as later lines tracing back to that root) include the Yoshioka-ryū (吉岡流), the Kurama-ryū (鞍馬流, sometimes given as Kurama-hachi-ryū), and the Chūjō-ryū (中条流, also read Nakajō-ryū) founded by Chūjō Nagahide — itself the ancestor of Tomita-ryū and ultimately Ittō-ryū. Another folklore says that Yoshioka Naomoto, who first used the title of Kenpō, is the founder.

The Kyō Hachi-ryū is usually paired with the Kantō Shichi-ryū / Kashima Shichi-ryū (関東七流), the seven eastern traditions associated with Kashima Jingū, which has a comparably murky pre-history but a more continuous documentary trail through Iizasa Chōisai and the Katori-Kashima lineages. The historically defensible position is that organized, transmissible ryūha with documented densho really begin in the 15th century with figures like Iizasa Chōisai Ienao (Katori Shintō-ryū) and Aisu Ikōsai (Kage-ryū); anything earlier, including the Kyō Hachi, is best treated as origin myth that later schools used to anchor their authority.

Kiichi Hōgen

There is no historically documented Kiichi Hōgen-ryū, no. Kiichi Hōgen functions in the tradition as the legendary progenitor of the Kyō Hachi-ryū as a whole rather than as the eponymous founder of a single named line. "Hōgen" is itself an honorific title for a monk rather than a name, and the character is largely a literary one — he appears in the Gikeiki (義経記), the early-Muromachi war tale about Yoshitsune, and later in jōruri and kabuki, most famously Kiichi Hōgen Sanryaku no Maki (鬼一法眼三略巻). No densho, makimono, or lineage chart of a "Kiichi Hōgen-ryū" with verifiable transmission survives.

Kiichi Hōgen Sanraku no Maki

His name appears as a claimed source within the mythic prehistories of several later schools. The Bujinkan traditions, for instance, invoke him: in the Takagi Yōshin-ryū's Ryuko no maki, Kiichi Hōgen is mentioned as a prominent figure whose teachings were embraced among many of the martial arts schools that came from western Japan, and a fragment attributed to him — "if it comes, meet it; if it leaves, send it away; 5 and 5 are 10, 2 and 8 are 10" — is preserved there. Some early-Edo writers also tried to identify his style retrospectively with Chūjō-ryū on the basis of a short tachi and close-range technique, but this is speculation rather than evidence of a distinct Kiichi Hōgen-ryū.

Maō-no-Taki

The waterfall beside the Kiichi Hōgen-sha (鬼一法眼社) at Kurama is named Maō-no-Taki (魔王の滝), "the Demon King's Waterfall," after Gohō Maō-son — the kami enshrined in the small hokora on the cliff above it. It sits in an area called Gohōkyō (護法境) just past the Fumyōden cable-car station, alongside the Hōjōike pond, the Yoshikura Inari-sha, and the Kiichi Hōgen-sha. Visitors often associate the waterfall with Kiichi Hōgen because the shrine's torii is positioned facing the falls rather than the shrine building itself, but the falls' formal name belongs to Maō-son.

The site is part of the long-established Kurama-dera approach and its sacralization is old, but the present physical structures are very recent. The Kiichi Hōgen-sha enshrines Kiichi Hōgen, who is said to have transmitted military arts to Ushiwakamaru; it was damaged by a fallen tree in the 2018 (Heisei 30) typhoon, dismantled, and rebuilt in 2025 (Reiwa 7). The Maō-no-Taki, which flows beside the Kiichi Hōgen-sha, also collapsed in the 2018 typhoon and was reconstructed in 2024 (Reiwa 6). So what one sees today is essentially a 2024–2025 restoration.

The Kiichi Hōgen association in the Kurama area more broadly is older but still secondary. The 1711 (Shōtoku 1) text Sanshū Meiseki-shi (山州名跡志) already records a "Kiichi Hōgen-zuka" at this locale, describing it as the place where the man said to be Yoshitsune's military-arts teacher had a mound, though the text itself notes the origin was already unverified. The visible stone monument labeled Kiichi Hōgen no Koseki (鬼一法眼之古跡), next to Kurama Elementary School, was erected on 10 November 1915 (Taishō 4) by the school's staff and students. So: mid-Edo at the earliest as a recognized tradition on the ground, with the current marker being early-20th-century.

Sōjōbō and Gohō Maō-son

The relationship between Sōjōbō and Gohō Maō-son is doctrinally formalized but historically layered, and most of the current synthesis is surprisingly recent. In present-day Kurama-kōkyō doctrine, Gohō Maō-son — also called Kurama-san Maō Daisōjō — is the great tengu and one body of the Sonten triad, and he holds Kurama-san Sōjōbō as a subordinate, or alternatively the two are identified as the same being. This teaching took its current form only after Kurama-kōkyō became independent from the Tendai school in 1949. So when the temple's modern literature treats Sōjōbō as Maō-son's lieutenant (or as a partial manifestation), that is essentially a Shōwa-era reformulation by Shigaraki Kōun and his successors.

Before that consolidation, the two figures had quite different pedigrees. Sōjōbō is the older, well-attested figure: he appears as the chief tengu of Kurama in the Muromachi-period Noh play Kurama Tengu, and Edo-period tengu compendia such as Hayashi Jiken's Zassetsu Nōwa (雑説嚢話, 1764) list him as the second of the Hachi Daitengu (eight great tengu of Japan), after Atago Tarōbō. In the classical Hachi Tengu lists and in the Kurama Daimaō-son Wasan preserved in the Shingon Zaike Mantokushū, "Kurama-san Sōjōbō" appears, but "Kurama-san Maō Daisōjō" does not. The compound title "Maō Daisōjō" itself only seems to surface in print with Kita Sadakichi's 1922 (Taishō 11) ethnographic study on possession cults, so it is a Taishō-era construction.

Maō-son in his current cosmological form is even more clearly modern. The Kurama-dera explanation holds that Maō-son descended from Venus 6.5 million years ago to save the earth, landing on the iwakura where Oku-no-in Maō-den now stands. This Venus/Sanat-Kumara identification is borrowed from Theosophy (via Blavatsky and Leadbeater) and was grafted onto Kurama's older Bishamonten-centered cult by Kurama-kōkyō. That said, there are pre-modern threads that made the later fusion natural: the omaedachi statue of Maō-son kept in front of the hibutsu at the Hondō Kondō depicts him as a sennin-like figure with wings on his back, a long beard, and a high nose, with a halo made of leaves — the statue in the Tahōtō has the same form — and from this it is thought that the "Kurama tengu" was originally Gohō Maō-son. So iconographically, Maō-son was already tengu-shaped well before the modern doctrine formalized the chain of command — see Zassetsu Nōwa (雑説嚢話) by Hayashi Jiken (林自見).

Maō-son as a religious figure — distinct from his current cosmological gloss regarding Venus — is attested at Kurama at least back to the late Muromachi period through a painting attributed to Kanō Motonobu (狩野元信, 1476–1559) and titled Suijaku Maō Daisōjō (垂跡魔王大僧正). The 1924 (Taishō 13) visit of Empress Teimei to Kurama-dera documents the pre-modern arrangement of the Hondō: the bettō Shigaraki Kōun records that when Empress Teimei made her royal visit on 3 December 1924, the Hondō housed the honzon Bishamonten in the center, the honji Senju Kannon Bosatsu in the east room, and the suijaku Maō Daisōjō in the west room; the "Maō-son" painting by Kanō Hōgen referenced here is the suijaku Maō Daisōjō by Kanō Motonobu.

The older arrangement had Maō-son in a strictly subordinate honji-suijaku role: Bishamonten is the honzon (the actual focus of worship), Senju Kannon is the honji (the underlying Buddhist truth), and Maō Daisōjō is the suijaku (the local-manifestation form).

Maō (魔王) in Buddhist cosmology is the king of Māra — the tempter who attacked Śākyamuni at Bodh Gaya. Prefixing gohō (護法, dharma-protecting) inverts the figure: the King of Demons converted and now serving as protector. This is the same structural pattern that produced Daikokuten (Mahākāla, originally a wrathful Śiva form), Aizen Myō-ō, the Twelve Heavenly Generals of Yakushi, and many others — converted-demon protectors are a major class of Mikkyō deity. Read this way, Gohō Maō-son is simply Kurama-dera's local converted-demon figure, paired with the orthodox Bishamonten as the temple's protector. The tengu iconography slots in here because tengu in medieval Buddhism are also categorized as converted/demonic mountain spirits — the leaf-haloed, winged, beaked image of Maō-son is iconographically a high-ranking tengu of converted-demon type.

In the Kurama-kōkyō explanation, the honzon of the Hondō Kondō is the "Sonten," a single unity of three bodies: Bishamonten in the center, Senju Kannon to the right, and Gohō Maō-son to the left. Sonten is described as "the universal energy that allows all life to live and exist." Bishamonten is the symbol of light, the spirit of the sun; Senju Kannon is the symbol of love, the spirit of the moon-disc; and Maō-son is the symbol of power, the spirit-king of the great earth. The mantra:

"Tsuki no yō ni utsukushiku, taiyō no yō ni atatakaku, daichi no yō ni chikara-zuyoku, subete wa Sonten ni te mashimasu"

Beautiful as the moon, warm as the sun, strong as the earth, all is in Sonten"

is recited as the basic devotional formula. Maō-den reverence likely started as a pre-Buddhist rock formation iwakura () veneration.

At Kuramadera, the honzon Sonten in the Hondō is a hibutsu (secret Buddha) opened only once every 60 years, in the hinoe-tora (fire-tiger) year, because Bishamonten is said to appear in the tiger month, tiger day, and tiger hour; this is why the Hondō is flanked by stone tigers (komatora) instead of the usual komainu. Most recent opening: 1986. Next opening: 2046. The substitute omaedachi statues — those tengu-form Maō-son figures with the leaf halo — stand in for the hibutsu during the long closed periods, which is why their iconography is what visitors actually see today.

Sōjōbō is the legitimate medieval/early-modern chief tengu of Kurama and the figure of the Yoshitsune legends — possibly an encoding over time of the historical Kiichi Hōgen — while Maō-son is the temple's tutelary "shadow side" of Bishamonten, whose iconography overlapped with tengu imagery.

In some folk religion, Sōjōbō's superior is Gohō Maō-son, who is considered the "god" of tengu society, and Maō-son is said to be the night-form of Bishamonten, the protector deity of Kurama-zan. This is a folk-theological way of resolving the apparent doubling — Bishamonten as the orthodox honzon and Maō-son as the unorthodox tengu-king — into a single deity with diurnal and nocturnal aspects. It doesn't appear in formal Kurama-kōkyō doctrine but captures the idea that the temple's daylit, normative face is Bishamonten, and its night, mountain-ascetic, tengu face is Maō-son.

The explicit hierarchy placing Sōjōbō under Maō-den is likely a 20th-century sectarian articulation, and not something contemporary to the time in which martial traditions emerged venerating these figures. The orthodox-Buddhist substratum listing Gohō Maō as a converted-demon dharma-protector, structurally similar to Daikokuten or the Twelve Heavenly Generals — was present in pre-modern times, grafted onto what appears to have been an older iwakura cult at the Oku-no-in rock formation for which no documentation survives.

The Tengu of Yagyū Shinkage-ryū

In Yagyū Shinkage-ryū, the eight Tengushō (天狗抄) kata have two parallel naming layers:

I. The working names – Kasha, Akemi, Zentai, Tebiki, Ranken, Nitō (or Nigusoku), Nitō-uchimono, Futari-gakari – are the technical names actually used in transmission.

II. The tengu names appear in the picture catalog (絵目録) attached to Sekishūsai Munetoshi's Shinkage-ryū Heihō Mokuroku no Koto, where the picture-catalog Tengushō kata are individually labeled "Kōrin-bō, Fūgan-bō, Tarō-bō, Ei'i-bō, Chira-ten, Karan-bō, Shutoku-bō, Konpira-bō" totaling eight, while the Yagyū-ryū Shinpishō Tengushō gives the names "Kasha, Akemi, Zentai, Tebiki, Ranken, Nigusoku, Uchimono, Futarigakari".

None of the names match by pronunciation. Old Yagyū commentary makes clear this was deliberate concealment — the tengu names served as cipher to hide (秘して) the actual technique names. Were the cipher labels of Tengu names drawn from the standard Edo-period pantheon of enshrined tengu? Partially yes, in a way that aligns with the Tengu-kyō 48 Tengu (四十八天狗) list. Pairing the eight Tengushō tengu against the Edo Tengu-kyō and surviving shrines:

Tarō-bō: Mt. Atago

Tarō-bō (太郎坊) is Atago-yama Tarōbō, head of the Hachi Daitengu and the senior tengu of Japan in the eight tengu — Atago-yama Tarōbō of Kyoto, Hira-san Jirō-bō of Shiga, Kurama-yama Sōjōbō of Kyoto, Iizuna-san Saburō-bō of Nagano, Ōyama Hōki-bō of Kanagawa, Hikosan Buzen-bō of Fukuoka, Ōmine-san Zenki-bō of Nara, and Shiramine Sagami-bō of Kagawa, with Atago-yama Tarōbō as the foremost. He is enshrined at Atago Jinja on Mt. Atago, and separately at Tarōbō-gū (Aga Jinja) on Akagami-yama in Higashi-Ōmi.

Atago Dai Gongen

Atago Dai Gongen (the Great Avatar of Mount Atago) is the local Japanese avatar (gongen) of the Buddhist Bodhisattva Jizō (Kṣitigarbha).

See also Yoshitoshi's Shinkei Sanjūrokkaisen (新形三十六怪撰, 36 Ghosts) for a depiction of Tarōbō.

Konpira-bō: Mt. Konpira

Konpira-bō (金毘羅房) is the Kuro-kenzoku Konpira-bō of Konpira-san in Kagawa Prefecture — i.e., Kotohira-gū.

Konpira-bō is associated with Konpira Daigongen (金毘羅大権現), the tutelary deity of Mt. Zōzu-san (象頭山) in Sanuki Province (modern Kagawa Prefecture, Shikoku). In the pre-Meiji honji-suijaku framework, the cultic center was Matsuo-ji Kongōin (松尾寺金光院), a Shingon temple-shrine complex; after the 1868 shinbutsu-bunri it was reorganized as Kotohira-gū (金刀比羅宮), the major shrine still standing on the mountain today. The Konpira deity was enshrined as the protective god of Kongōin Matsuo-ji on Zōzu-san; in the medieval period the name was changed to Konpira Daigongen under the influence of honji-suijaku doctrine, with Kongōin acting as bettō. In the Meiji period, when shinbutsu-konkō was prohibited, Kongōin was abolished and in the sixth month of Meiji 1 became Kotohira Jinja, then renamed Kotohira-gū in the seventh month. Post-Meiji, the formal kami is Ōmononushi-no-mikoto (大物主神), treated in State Shinto doctrine as the suijaku of the older Konpira deity.

The honji-suijaku genealogy goes deeper than that. "Konpira" is a transliteration of the Sanskrit Kumbhīra (कुम्भीर), originally a crocodile/makara water-deity in Indian mythology, absorbed into Buddhism as one of the Twelve Heavenly Generals (十二神将) attending Bhaiṣajyaguru (Yakushi Nyorai). Konpira Daigongen is essentially Kumbhīra grafted onto a jinushi-gami (local landowner kami) of Mt. Zōzu through the standard medieval gongen-formation pattern — a Buddhist deity localized through a shugen mountain cult.

In the Edo period, white-robed Konpira pilgrims (gyōnin) carrying tengu masks on their backs travelled the country spreading Konpira belief, and a custom emerged in which pilgrims going to Sanuki Zōzu-san Konpira Daigongen for the Konpira-mairi pilgrimage would carry a tengu mask on their back. The deity was iconographically depicted as a winged, feather-fan-bearing tengu, particularly in rain-making contexts (the Konpira cult also absorbed strong water/sea-protection and amagoi functions, partly via the Shiwaku-island sea-merchants who propagated the cult along their shipping routes).

The Konpira tengu is today counted as one of the three Sanuki tengu and called Kongō-bō; the other two are Chūjō-bō of Yakuri-ji and Sagami-bō of Shiramine-ji. So if you want the local tengu identity, it is Zōzu-san Kongō-bō (象頭山金剛坊), while in the Tengu-kyō 48-list the same figure appears under the more cosmic title Kuro-kenzoku Konpira-bō (黒眷属金比羅坊, "Black Retinue Konpira-bō").

The Edo-period Nihon Daitengu Banzuke (Japan Great Tengu Ranking) places Atago-san and Kurama-san at yokozuna/ōzeki level and Shiramine Sagami-bō at komusubi, with Zōzu-san Kongō-bō, Goken-zan Chūjō-bō, and Zōzu-san Shukai-bō appearing only at maegashira rank from Sanuki. That is to say, Konpira-bō in the Tengu-kyō is a real cult identity but a junior one in the Edo pantheon.

This is consistent with the Yagyū Tengushō naming pool: Sekishūsai drew from across the entire 48-list, not just the elite eight, when assigning cipher labels to the individual kata.

Kōrin-bō: Mt. Kōya

Kōrin-bō (高林坊) corresponds to Kōyasan Kōrin-bō of Mt. Kōya in Wakayama Prefecture, a major mountain-cult center with its own chinju-sha system (Niutsuhime Jinja, Kōya Myōjin).

Kōrin-bō differs sharply from Konpira-bō. Konpira-bō is unusual in having an actual gongen attached to him; Kōrin-bō does not. He is best read as a place-tengu label for Mt. Kōya in the Tengu-kyō 48 list rather than as a discrete cultic figure with his own honji. There is no "Kōrin Daigongen" to which he is the tengu-attendant.

There are two Buddhist axes to Kōyasan.

First, the doctrinal honzon axis: Dainichi Nyorai (大日如来), the dharmakāya buddha central to Shingon mikkyō, enshrined in the Konpon Daitō (根本大塔) and Kondō (金堂) of the Danjō Garan. Second, the founder cult — Kōbō Daishi Kūkai (弘法大師空海), believed to be in continuous nyūjō (永遠の瞑想; eternal samādhi) at Oku-no-in. Oku-no-in is the site of Kōbō Daishi's mausoleum; Daishi entered nyūjō at the age of 62 in 835, and for 1,200 years has been believed to continue his eternal meditation in this place. Around these, the Mikkyō pantheon of Fudō Myō-ō, Aizen Myō-ō, the Eight Patriarchs, the Twelve Heavenly Generals, and so on populate the temple halls. For an esoteric mountain like Kōya, where you would normally expect a head-tengu of some substantive standing, the cult focus is so heavily on Daishi-shinkō and the dharmakāya buddha that a tengu cult never crystallized — Kōrin-bō remained nomina

Second, The gongen / kami axis: the Kōya Shisho Myōjin (高野四所 明神). Kōrin-bō, qua mountain-spirit, sits within the tutelary kami system of Kōya rather than the Buddhist hall system. The shrine is also called the Niu Shisho Myōjin or Amano Taisha, and is known from antiquity as the tutelary deity (chinju) of Kōyasan. From the first to the fourth hall it enshrines four pillars: Niu Myōjin, who had long been worshipped there, Kariba (Kōya) Myōjin, who was connected to the opening of Kōyasan, and Kehi Myōjin and Itsukushima Myōjin, both added by 1208 (Jōgen 2):

1. Niu Myōjin / Niutsuhime Ōkami (丹生明神 / 丹生都比売大神) — first hall. The mother kami, jinushi-gami of the mountain. Cinnabar/mining associations through the historic Niu clan (丹生氏). Pre-Kūkai cult.
2. Kariba Myōjin / Kōya Myōjin / Kōya Mikogami (狩場明神 / 高野明神 / 高野御子大神) — second hall. The son-kami of Niutsuhime; according to the tradition, when Kūkai opened Kōyasan in 816 (Kōnin 7), Kōya Mikogami manifested as a hunter accompanied by two dogs, one black and one white, who guided Kūkai to the site. The Konjaku Monogatari preserves this story. He is also known as Kōya Myōjin or Inukai Myōjin. Kotobank
3. Kehi Myōjin (気比明神) — third hall. Agricultural / grain deity, summoned from Kehi Jingū in Echizen in the Kamakura period via takusen.
4. Itsukushima Myōjin (厳島明神) — fourth hall. Sea / commerce / arts deity, summoned from Itsukushima in Aki, identified post-medieval with Benzaiten.

These four kami are the gongen-level layer of Kōyasan that a tengu of the mountain — Kōrin-bō, if you will — would conceptually attend on. In the medieval temple iconography they are typically rendered together as the Kōya Shisho Myōjin-zu (高野四所明神図).

The most commonly cited pairings within Kōyasan jōō-ji (高野山定置) practice are: Niu Myōjin ↔ Dainichi Nyorai (or in some accounts Aizen Myō-ō); Kariba Myōjin ↔ Fudō Myō-ō (or Jūichimen Kannon in some kakejiku); Kehi Myōjin ↔ Yakushi Nyorai; Itsukushima Myōjin ↔ Jūichimen Kannon (and later, popularly, Benzaiten as Shinto-side counterpart).

Konpira-san was a shugen (mountain-religion) site whose deity was iconographically a tengu and whose pilgrims literally wore tengu masks, so the Tengu-kyō name Konpira-bō (or Kongō-bō, the local form) maps onto a real cultic identity. Kōyasan was a Shingon orthodoxy site that, from Kūkai onward, deliberately subordinated mountain-ascetic and tengu lore to the formal honji-suijaku of the Shisho Myōjin and to Daishi-shinkō. The mountain did host shugen activity at the periphery (the Kōya Hijiri 高野聖, the linked Katsuragi shugen circuit), and the Konjaku Monogatari contains tengu-incident stories around Kōyasan; but no Kōya tengu got the cult-elevation Konpira did. Kōrin-bō is therefore in the catalog because every famous mountain needs an entry, not because there was a specific tengu shrine there for Sekishūsai to point to.

Functionally for the Yagyū cipher this didn't matter: the label needed only to sound like a tengu name pulled from the pantheon.

Chira-ten: A Visitor to Mt. Hiei

Chira-ten (智羅天) is the Hieizan-associated tengu of literature: in Konjaku Monogatari, vol. 20, story 2 — Shintan Tengu Chira-Eiju Kono Chō ni Watarukoto — a powerful tengu from China named Chira-Eiju is described as having crossed to Japan and met with the tengu of this country. He gets badly mauled in a power-contest with the Hiei monks; the figure is more a cautionary literary trope than an object of cult, so there is no shrine, but the Hieizan/Yokawa landscape is the implicit setting for this figure.

The Yagyū Tengushō is thus drawing not only on tengu catalogues from the early Edo period, but general literature of the time. What is interesting here is the association with China — some analyses of the Tengushō hypothesize (cf. Knudsen's work on Tengu) that techniques were drawn from Chinese or even European sword methods encountered in China.

The 智羅天 of Sekishūsai's catalog and the 智羅永寿 (Chira-Eiju) of Konjaku Monogatari vol. 20, tale 2, are also the same figure as Zegai-bō (是界坊 / 是害房) and, in some manuscripts, Zenkai-bō (善界坊). In Konjaku-shū vol. 20, tale 2 the figure appears as "Shintan Tengu Chira-Eiju watarukoto," and the same story is the source of the Noh play "Zegai" composed by Takeda Hōin Munemori, based on this story and on the Zegai-bō Emaki. The earliest extant complete copy of the Zegai-bō Emaki is the Manshu-in (Kyoto) two-scroll set, dated 1354 (Bunna 3). The reading 智羅天 in the Yagyū document is most plausibly a contraction or scribal shorthand for Chira[-eiju] tengu, with 天 doing the work of 天狗.

In the Noh drama Zegai cycle, Zegai-bō, a tengu proud of having lured all the self-conceited people of China into the tengu-realm, comes to Japan to expand his domain; he visits Tarō-bō, the tengu of Mount Atago, and tells him about his plan to obstruct the Buddha-Dharma in Japan; Tarō-bō agrees and recommends Mt. Hiei; Zegai-bō is hesitant because he fears Fudō Myō-ō, the immovable defender who fiercely guards the temple; but Tarō-bō pushes him and offers to be his guide, and the two depart together on a cloud for Mt. Hiei.

Tarō-bō (#3) and Chira-ten (#5) in the Yagyū Tengushō are not unrelated tengu names selected from the 48-list — they are paired protagonists in a single famous story — their kata are physically also quite similar.

The Konjaku version of the tale specifies the high priests of Yokawa who repulse Zegai-bō. The named figures across the textual layers include Yokei Risshi (余慶律師) of Iimuro, Jie Daishi Ryōgen (慈恵大師良源) — better known as Ganzan Daishi (元三大師) — and Jinin Wajō (慈忍和尚) of Iimuro. The defeat scenes vary by version: in some Zegai-bō is humiliated by adult priests, in others by young temple-boys (童部, dōbu) — which is the more comic register favored in the emaki and Noh.

In the emaki tradition, Zegai-bō is beaten very strongly by young novices and even has his wings burned; he is badly hurt, and the Japanese tengu eventually tend to him in a hot bath at Kamogawa to heal him, and after his recovery hold a large farewell party for him before he returns to China.

Other Tengu

Fūgan-bō (風眼坊), Ei'i-bō (栄意坊), Karan-bō (火乱房), and Shutoku-bō (修徳房) do not appear in the Tengu-kyō 48 list under those exact characters, and it is not clear if there is a documented shrine for any of them.

Several look like they may be either local lesser-tengu names, deliberate fabrications for the cipher, or variants whose readings have drifted — 修徳房 could conceivably be a graphic variant of Shūtoku, faintly evoking Sutoku-in, but the canonical Sutoku tengu in the Hachi Daitengu is Shiramine Sagami-bō, not 修徳. Given the picture catalog's stated purpose of concealment, it would not be surprising if Sekishūsai or his scribes invented or mangled some of the names precisely to prevent outsiders from decoding the contents.

Order of Precedence

Of the eight Tengushō cipher-names, three (Tarō-bō, Konpira-bō, Kōrin-bō) map cleanly onto major enshrined mountain tengu, one (Chira-ten) is a literary Hieizan-area tengu without a shrine, and four appear to be obscure or possibly artificial — consistent with the catalog's explicit role as a secret-keeping device rather than a devotional pantheon. No attribute of a given tengu encodes anything about the kata it labels. The function of the substitution, per the Yagyū lineage's own commentary in Yagyū Genshū-den no Kenkyū (柳生厳周伝の研究). is concealment of names from outsiders reading the densho, nothing more.

The mapping, as preserved in Sekishūsai's Shinkage-ryū Heihō Mokuroku no Koto picture catalog, is discussed in Akabane Tatsuo's research (Yagyū Genshū-den no Kenkyū). Akabane cites Kanbe Kinshichi's view that the Hōzan-ji-held catalog ascribed to Sekishūsai is itself a e-soragoto (絵空ごと), a stylized representation rather than a literal record. So the catalog's job is to circulate the sequence and the images under names that mean nothing to an outsider; the densho holder reads it knowing which list maps to which.

The order is not perfectly invariant across Yagyū lines. From Sekishūsai's documents downward, the Edo Yagyū transmission via the Yagyū-ke Komokuroku Kudensho gives the sequence as Kasha, Akemi, Zentai, Tebiki, Ranken, Nigusoku-uchimono, and Futari-kakari. In contrast, Renya's revised Uchitachi Mokuroku Kudensho and Joryūsai's Uchitachi Mokuroku both give Kasha, Akemi, Zentai, Tebiki, Nitō, Nitō-uchimono, Futari-kakari, Ranken as the list, placing Ranken last and Futari-kakari second-to-last.

The Yagyū-ryū Shinpishō gloss on the eighth Tengushō kata, titled "Tengushō #8 Konpira-bō," is in fact a commentary on Futari-gakari — referring to 細道の二人相とて、跡先より挟まれたる時 or "being flanked front-and-rear in a narrow path", which is a two-opponent situation — in contemporary Yagyū practice considered to be the oku kata of the set.

Sekishūsai's original Emokuroku order (which is the only one with the tengu names attached) defines the cipher; later technical re-orderings reshuffled the kata sequence without reshuffling the cipher labels, which is partly why the correspondence looks inconsistent if you cross-reference Edo-line modern publications with Owari-line modern publications.

People occasionally try to read semantic content into pairings — e.g., Kōrin (高林, "tall grove") as a hint at kuneri-tachi and the lateral footwork of Kasha, or Karan (火乱, "fire-chaos") as a gloss on the two-sword scramble of Nigusoku, but this is not supported by historical densho commentary. Sekishūsai's catalog uses tengu names because tengu names were the natural pool of plausibly-meaningful-sounding but technically-empty labels for a Sengoku-era warrior with mountain-religion background; the choice of which tengu got slot #3 versus slot #6 carries no doctrinal weight.

Okugi no Tachi

The tengu-name cipher is specific to the eight Tengushō (天狗抄), and stops there. The six Ōgi no Tachi / Okugi no Tachi (奥義之太刀) that follow appear in the Emokuroku under their own technical names with no tengu substitution:

1. Tensai-ransai 添截乱截 (or Soissai-ransai, depending on lineage reading)
2. Munito-ken 無二剣
3. Katsujin-ken 活人剣
4. Kōjō 向上 (also written 高上 in older mokuroku)
5. Gokui 極意
6. Shinmyō-ken 神妙剣

The Emokuroku doesn't illustrate all six Ōgi no Tachi equally. In the picture-catalog, from the first Sangaku kata "Ittō Ryōdan" through the Kyūka, the eight Tengushō, and Katsujin-tō, the kata are recorded with pictures and detailed text; "Kōjō, Gokui, and Shinmyō-ken" have no pictures, only the technical text; and "Hakka Hisshō" and the Nijūshichi-kajō Saiai are listed by name only. So the catalog operates with a graduated concealment scheme.

The Sangaku and Kūka have full pictures and untranslated names — these are the foundation curriculum, no protection required. The Tengushō have pictures and the tengu-name cipher — visually revealed, lexically concealed. The first three Ōgi (Soissai-ransai, Munito-ken, Katsujin-ken) have pictures and their plain names — by this point the practitioner is far enough in that suijaku-style cover is unnecessary. The last three Ōgi (Kōjō, Gokui, Shinmyō-ken) have names but no pictures — the inverse protection mode, where the concept is named but the technique is withheld from the page entirely. Then Hakka Hisshō and the Nijūshichi-kajō Saiai appear as bare titles, with neither picture nor description, signaling oral-only transmission.

Kōjō and Shinmyō-ken are found in parallel Jiki Shinkage-ryū mokuroku.

The Tengushō's cipher is a mid-tier protection device. It belongs to the curriculum band where the kata is visualizable enough to need an illustration but secret enough to need lexical cover. Once the syllabus moves into the Ōgi proper, the protection scheme shifts from cipher to omission — names without pictures, and finally names without descriptions. The semantic content of the Ōgi names — muni "no-two," gokui "innermost meaning," shinmyō "divinely-mysterious," katsujin "life-giving" — is itself doctrinal-philosophical rather than technique-descriptive, so the names themselves already function as a kind of natural cipher: even told Shinmyō-ken, an outsider learns nothing about how the kata is performed. Sekishūsai's catalog uses tengu labels precisely where the kata-names would have leaked technical content (Kasha, Tebiki, Nigusoku — fairly descriptive of what is being done), and abandons the device once the kata-names become abstract enough to be self-protecting.
