This version draws on Chinese materials cited in the Edo-period encyclopedic Wakan Sansai Zue and on Toriyama Sekien’s pictorial interpretation. The mountain spirit lurks in the hills, watching mountain huts where salt is set out for cooking or work and edging closer to them. Sources differ on size, some saying about one shaku while others claim three to four shaku. Its hallmark is a single leg with a heel set backward, making its tracks hard to read. It favors small wetland creatures like crabs and frogs and appears along stream gullies. It is said to bring lustful harm at night, but will retreat if the drought deity’s name “Batsu” (Hatsu/Boatsu, the Chinese demoness Ba) is spoken, a type of name-utterance apotropaic. Those who harm or consort with it suffer illness or fires, functioning as a cautionary taboo against contact. In Japan, Sekien labeled it “Yamaki” (mountain demon) and depicted it peering into a hut with a crab in hand, providing visual cues; local oral lore is scant, and treatment remains largely bibliographic. Modern reinterpretation is restrained, keeping to the contours of old records.
