A tree spirit from Chinese lore, said to inhabit venerable old trees. In the Soushenji, it emerges from a camphor tree, bleeding and appearing like a dog with a human face. In Japan, Edo-period natural histories and yokai picture scrolls present it as a Chinese entity akin to kimyō or kodama—tree spirits. Linked to beliefs about echoes in the mountains, it has been discussed as an antecedent to the dog-shaped image of Yamabiko.
Folklore & Legends
Gan Bao’s Soushenji records that during the Wu period, when Jing Shu felled a giant camphor, blood gushed forth and a Penghou—dog-shaped with a human face—appeared; when boiled, it tasted like dog. In Japan, the Wakan Sansai Zue cites the Bencao Gangmu and introduces it as a kind of kimyō/kodama. The name appears in Kokon Hyakumonogatari Hyōban and Konjaku Hyakki Shūi, and early modern sources note that dog-shaped depictions of the echo spirit Yamabiko were influenced by the Penghou.
An Edo-period rendering of Penghou, organized within the Japanese concept of kodama after scholars and painters absorbed Chinese narratives. It is depicted as a dog with a human face, tied to venerable camphors and other old trees. Echoes in the mountains were taken as the work of tree spirits, and notes on Penghou informed dog-shaped variants within yamabiko imagery. Early modern natural histories cite Chinese texts explicitly, layering foreign entries atop local lore rather than reporting concrete regional怪談, so place-specific tales are scarce. Japanese accounts treat it as a “tree spirit,” equating kimoki with kodama, linking it to taboos on felling and the cult of ancient trees. Details vary across sources, but two elements persist: it appears bleeding from an old tree, and it bears a human-faced canine form. This version eschews embellished fiction to show how Chinese originals were received in Japanese encyclopedias.
