A study of late-Heian private poetry collections that examines poetic self-fashioning and editorial consciousness. The topic connects with Kenta Kobayashi's later articles and research projects on Insei-period and classical-medieval waka.

The work reads late-Heian waka through the form of the private poetry collection and its consciousness of self-presentation and compilation.

This scholarly study rereads the widely circulated texts of Hogen monogatari and Heiji monogatari through the interaction of literature and society in the late Muromachi and Sengoku periods. It traces formation, mutual influence, and modes of adaptation to examine how these war tales were read and reinterpreted in later periods.

Through the adaptations of the widely circulated texts, the book illuminates the relationship between literature and society in an age of upheaval.
