From an Internet Archive Blog Post:
….the Internet Archive is thrilled to announce a new partnership with the University of Tokyo General Library. Spearheaded by Masaya Nakatake as a member of the UTokyo Academic Archives Project Office, the Internet Archive partnership provides expanded access and a digital backup for some of the library’s most precious artifacts.
Since June 2020, our Collections team has worked in tandem with [University of Tokyo General Library] staff to ingest thousands of digital files from the General Library’s servers, mapping the metadata for over 4,000 priceless scrolls, texts, and papers. The collection, representing meticulous digitization efforts by Japanese historians and scholars, showcases hundreds of years of rich Japanese history expressed through prose, poetry, and artwork.
Among the highlights of the holdings are manuscripts and annotated books from the personal collection of the novelist Mori Ōgai (1862–1922), an early manuscript of the Tale of Genji, and a unique collection of Chinese legal records from the Ming Dynasty.
