is a classic work of Japanese literature written by the noblewoman and lady-in-waiting Murasaki Shikibu in the early years of the 11th century, around the peak of the Heian period. It is sometimes called the world's first novel, the first modern novel, the first psychological novel or the first novel still to be considered a classic. Notably, the work also illustrates a unique depiction of the lifestyles of high courtiers during the Heian period. While regarded as a masterpiece, its precise classification and influence in both the Western and Eastern canons has been a matter of debate.
