Sasaki Kizen was a folktale collector and writer from the Tono region of Iwate Prefecture. Sometimes called “the Grimm of Japan,” he gathered and recorded many folktales of northern Japan.
The stories of his hometown that he told to Yanagita Kunio were published in 1910 as The Legends of Tono. Many of Tono’s famous strange tales, such as those of the kappa, people spirited away and zashiki-warashi, come from Sasaki. He later published folktale collections of his own, such as Kikimimi Soshi.
