In 2015, Princeton University East Asian Library acquired an ephemera collection from the Yoshino region of Nara Prefecture which contains various types of documents from the medieval to the Showa period. Princeton University and the Historiographical Institute of the University of Tokyo (HIUT) conducted a joint research in 2018 and 2019 to investigate about 150 pieces of fragmentary leaves from 14th century to 17th century in the collection.
