Most of the original "Rakuyōshū" copies were lost. Today, only four complete copies, two incomplete copies and two collections of fragments are known. Two complete copies were survived during the turbulent feudal period of Japanese history: one is now held by the Tenri Central Library, in Tenri, Nara, and the other is held by the British Library through Ernest Satow who bought this copy from antique dealer in Edo. Other two complete copies are preserved in Europe, by the Earl of Balcarres, and the Society of Jesus in Rome. Two "Rakuyūshū" copies missing Part (3) are owned by the Leiden University Library and the Bibliothèque Nationale in Paris. Two collections of fragments are held by the Tenri Central Library, Bibliothèque Nationale of France, respectively.
