Classic folktales such as Momotarō, which most Japanese today are familiarized through pictured children's storybooks, manga, or other popularizations, can be traced to picture-books printed in the Edo period, though their prototypical stories may go back much further. The versions retold by children's story author Sazanami Iwaya [ja] (1870–1933)[14] had a strong hand in establishing the forms usually known today.
