Shokuin (Zhu Yin)

Their soul is listening — speak, and they will answer.

Basic Description

Shokuin is a northern divinity described in the Shan Hai Jing, depicted with a human face and a serpent’s body. When its eyes open, day begins; when they close, night falls. Its breath brings winter, and its call ushers in summer—thus governing the cycle of day and night and the turning of the seasons. The text reached Japan in antiquity, and early modern yokai picture scrolls introduced Shokuin as a foreign deity. Japanese sources offer little on its specific rites or behavior.

Folklore & Legends

Accounts stem from Chinese classics, placing it at the foot of northern mountains. It neither eats nor drinks, and its breath becomes wind. Some variants of the Shan Hai Jing equate it with the Candle Dragon (Zhurong/‘Zhu Long’), a detail echoed in early modern Japanese picture scrolls and essays, though native Japanese oral traditions are scarce. From the Heian period onward, it was known through the reception of Chinese texts and illustrated in bestiaries and yokai art as a foreign spirit-deity.

Detailed Analysis

In Japan it is understood as a foreign divinity-spiritoriginating in the Classic of Mountains and Seas and related encyclopedic interests. Imagery follows the key points of a human face upon an immense red serpent body, whose opening and closing eyes divide day from night and whose breathing brings seasonal winds and heat or cold. Confusion with the Torch Dragon appears in early modern commentaries, yet most introductions cautiously note textual loci and descriptive differences, and signs of domestic worship are scarce. Consequently, local rites, taboos, and oral lore are meager, with reception centered on reading, sketching, and use as an art motif. It is often cited as an example of incorporating a foreign divinity into yokai catalogues and is positioned as a personification of time and the seasons.
