The term or sanjin, as understood in Japanese folklore, has come to be applied to a group, some scholars claim, of ancient, marginalized people, dating back to some unknown date during the Jōmon period of the history of Japan.

Tono Monogatari According to Yanagita, the Yamabito were "descendants of a real, separate aboriginal race of people who were long ago forced into the mountains by the Japanese who then populated the plains" during the Jōmon period. Yanagita wrote down these folktales in the book Tono Monogatari, though as author Sadler notes: Kamikakushi One of the concepts Yanagita presents in Tono Monogatari is that of, literally, being spirited away, or kamikakushi. As author Sadler relates: The Yamabito debate The stories found within Tono Monogatari are not without their detractors. Minakata Kumagusu was highly critical of Yangita's research, "heaping severe criticism and ridicule on belief that ... the Yamabito ever existed." According to records, between 1915–1916, the two scholars exchanged letters debating the existence of the Yamabito. In one famous letter, dated December, 1916, Minakata makes the following claim that while working with an assistant in the Wakayama region of Japan: Notes References Dickins , Frederick Victor.
