This study reads Asai Ryoi's Buddhist writings and kana-zoshi through the intersection of early modern publishing culture and religious thought. The award-winning research was titled A Study of Asai Ryoi's Buddhist Writings and Kana-zoshi, and related results were later published as Early Modern Buddhist Writings by Shintensha.

The study illuminates the intellectual links running from Asai Ryoi's Buddhist writings into kana-zoshi literature.

This research examines private waka collections from the late Heian into the medieval period through their compilation principles and forms. No standalone book publication matching the award title A Study of Late Heian Private Collections was confirmed, while Waseda University's repository provides the doctoral thesis A Study of Private Collections and Their Compilation Consciousness.

By reading arrangement and structure, the study asks how poets reshaped their own bodies of waka.
