These are copies of scrolls whose originals have been lost. There is a description in the Kofukuji scroll that says that this was copied by Kano Osanobu (Seisenin) (1796 - 1846) in 1817 from the original owned by the Edo Shogunate. Since the Kofukuji and Todaiji scrolls constitute a set, it seems safe to say that the Todaiji scroll was created at the same time by the same person. While the Kofukuji scroll depicts Yuimae, the most important Buddhist service at Kofukuji Temple, the Todaiji scroll depicts the Hall of the Great Buddha and Kaidai-in.
These are designated as attachments to an important cultural property, Tengu Zoshi (Tokyo National Museum A-31) of the Kamakura period.
