The letters on Shikishigami of Uji Byodo-in Temple Hoo-do (Phoenix Hall), also called Amida-do (Amitabha Buddha Hall), were written by Kaneyuki, and based on the handwriting of these letters, a cluster of ancient writings, such as 'Katsura-bon Manyoshu' (Katsura manuscript of 'Manyoshu,' the oldest anthology of waka in Japan) and the Second 'Koyagire' (Fragment from 'Kokin Waka Shu,' the poetry anthology), are supposed to have been handwritten by Kaneyuki.
