Otogizōshi (御伽草子 otogi-zōshi?) refers to a group of approximately 350 Japanese prose narratives written primarily in the Muromachi period (1392–1573). These illustrated short stories, which remain unattributed, together form one of the representative literary genres of the Japanese medieval era.
This type of short prose narrative from Japan is often considered a transitional genre, which bridges the gap between the courtly literature of the Heian period (794-1160) and the more plebeian kanazōshi (tales written in kana) and ukiyo-zōshi (tales of the floating world) of the Edo period (1600–1868). The stories were originally recorded in both illustrated scrolls or booklets (Nara-ehon) which link the picture scrolls of the Heian era with the woodblock print books of the Edo period. This suggests that otogizōshi were meant to be read aloud, with the illustrations serving as reference guides.
Because the stories were frequently recited before an audience, many narratives are simple, with little description, depth, or development. Others, however, are more poetically allusive, suggesting composition by literati. Many of the tales are straightforward quest narratives, often revolving around a single heroic figure. In order to advance the plot, the passage of time is swift, with characters sometimes aging years or decades in the space of a single sentence.
The vast topical range of Otogizōshi discourages easy generalization. The subject matter includes worldly concerns (love, marriage, family); spiritual matters (the pursuit of enlightenment, encounters with manifestations of the Buddha); martial adventures; farce, and supernatural fantasy. While some of the stories exhibit a clear didactic agenda, most otogizōshi appear to have been composed primarily for the sake of entertainment.
