Japanese folktales are an important cultural aspect of Japan. In commonplace usage, they signify a certain set of well-known classic tales, with a vague distinction of whether they fit the rigorous definition of "folktale" or not among various types of folklore. The admixed impostors are literate written pieces, dating back to the Muromachi period or even earlier times in the Middle Ages. These would not normally qualify for the English description "folktales".

Momotarō is a popular hero of Japanese folklore. His name is often translated as Peach Boy, but is directly translated as Peach + Tarō, a common Japanese given name. Momotarō is also the title of various books, films and other works that portray the tale of this hero.
