In the elevated context his father engendered, Hayashi Gahō (formerly Harukatsu), worked on editing a chronicle of Japanese emperors compiled in conformance with his father's principles. "Nihon Ōdai Ichiran" grew into a seven-volume text which was completed in 1650. Gahō himself was accepted as a noteworthy scholar in that period; but the Hayashi and the Shōhei-kō links to the work's circulation are part of the explanation for this work's 18th and 19th century popularity. Contemporary readers must have found some degree of usefulness in this summary drawn from historical records.
