This publication is an annotated edition of Inu Hyakunin Isshu. The Inu Hyakunin Isshu is a parody of the famous Hyakunin Isshu, and was published in 1669. The prologue was written by an unknown man named Yusoan. In the title Inu Hyakunin Isshu, the word inu means parody. The work is one of a number of parodies of classics that were produced in the early Tokugawa periods, such as Inu Tsurezure (a parody of Tsurezuregusa) and Inu Makura, a parody of makura no Soshi. Many other parodies of the Hyakunin Isshu were made in the Tokugawa period, but the Inu Hyakunin Isshu is of particular interest because of its early date.
