Tōkajin (桃果人, "Peach man") was a "man" who lived atop a cliff in the Togenkyo region, where he watched over the Ninmenka (human-faced peach tree). He used the Ninmenka to try and achieve immortality through the Fruit of Longevity. Tōkajin would "save" defeated or defected soldiers who were lost and hungry from war, shrink them down to size and make them train to become sages in his miniature village. When one of his apprentices would gain even minor spiritual stature, they would be put in Tōkajin's gourd, dissolved inside it, and thereafter become nourishment for Ninmenka.
