聖徳太子
Although traditionally attributed to the semi-mythological Prince Shōtoku, current scholarly consensus disputes this and the actual authorship of the texts are unknown. The "Hokke Gisho" contains a note stating, "This book belongs to the private collection of King Jōgū [Prince Shōtoku] and is not from overseas." However, the brush style is different from the main text and is believed to have been later added by the priest Gyōshin.
