The premise
A large fraction of Japan's monsters arrived by book: Chinese classics and encyclopedias (Shanhai Jing, Sancai Tuhui, the marvel-collections), received into Japanese natural-history (the Wakan Sansai Zue, 1712 — which catalogued the kappa, the nozuchi, and the shachihoko as fauna) and then into Sekien's plates. This page is the customs ledger: what crossed, and what each traveler declared.
The import table (drafted entries only)

| The hairy women (two branches) | Mao-nü the mountain immortal (keukegen); the Touxia Lu smoke-woman (kejōrō) | keukegen, kejoro |

| Dongfang Shuo's exclamation-beast | Sekien's iyaya caption | iyaya |

| The wind-bag | Hellenistic, via the whole Silk Road | fujin |
| The hopping corpse | Hong Kong cinema, one marketing cycle, 1980s | kyonshii |
| Bai Ze, the demon-census beast | the lost Bái Zé Tú; a monster whose power is bibliography | hakutaku |
| The guhuoniao, child-taking bird | Xuan Zhong Ji → Bencao Gangmu → Wakan Sansai Zue; fused with the native ubume | kokakuchō |
| The backwards-heeled mountain imp | Baopuzi via Wakan Sansai Zue → Sekien → Iwate field tradition | sansei |
The road's two cleanest specimens. The kokakuchō shows what full assimilation looks like: a Chinese bird-spirit of women dead in childbirth crosses as text, through the Bencao Gangmu into the Wakan Sansai Zue (1712, this page's recurring clearinghouse), and dissolves so completely into the native ubume that 姑獲鳥 became ubume's alternate spelling — one grief, two bodies, one entry. The sansei shows the same pipeline running one stage further: Baopuzi → Wakan Sansai Zue → Sekien's 1779 plate → and then out into Iwate folk tradition, where villagers were telling each other about a knee-high imp with its heels on backwards. That last arrow is the one this page exists to document. An import doesn't finish arriving when it's printed. It finishes when somebody who never read the book is afraid of it.
The road's own patron. One row above deserves lifting out of the table, because it is this page's thesis wearing a body. The hakutaku — Chinese Bai Ze — met the Yellow Emperor and dictated a complete catalog of every ghost and demon in the world, the lost Bái Zé Tú. A monster whose power is yokai bibliography. In Japan it became a nine-eyed, six-horned ox-lion whose picture wards off illness, and during Edo's 1858 cholera outbreak people were instructed to place its image on their pillows before sleeping — image-as-prophylaxis, dated to a real epidemic, and the tradition amabie inherited. Then the signature: Sekien closes his third catalog's roster with Hakutaku — the demon-cataloguer placing the demon-catalog's patron beast near the end of his own book. Whether he meant it or not, every bestiary since has been a descendant of the beast that was one, this one included.
The three customs regimes
- The encyclopedia regime (Wakan Sansai Zue): marvels admitted as fauna, with measurements — the nozuchi's 90 cm, the hihi's 7'8" capture, the akaei's three ri. Belief as natural history.
- The caption regime (Sekien): sources cited, sometimes invented (the dodomeki's unverifiable "Kakkan Gaishi" — "the Edo ancestor of every modern fabricated old record"). Scholarship as costume.
- The distribution regime (modern): the kyonshii's film-marketing arrival — "the receptor-sites are eternal even when the transmission is cinema."
What the road teaches
Imports localize by function, not form: Wu Gang's punishment became a love metaphor; the drought goddess became outhouse-disposable; the wind-bag became the kamikaze's luggage. The border these creatures actually crossed was not the sea but the job market — each was re-hired for whatever the receiving culture needed done.
