Also in 1922, during the Korea under Japanese rule under the supervision of then Resident-General of Korea Itō Hirobumi, many volumes of books including copies of Uigwe and other relics stored at the royal archive in the Buddhist temple at Odaesan were transferred to the University of Tokyo. In August 2010, then-Japanese Prime Minister Naoto Kan announced the return of the Uigwe to mark the centenary of the Japanese annexation of Korea. This was followed by the return of 1,200 volumes including 150 Uigwe in December 2011, which were subsequently kept at the National Palace Museum of Korea.
