Abstract
Documents formerly in the collections of the HIROHASHI and HINO families, now held in the National Archives
of Japan, were copied by the Cabinet Records Bureau from 1892 to 1893. Due to the nature of copied materials,
use of copies must take into consideration the extent to which they reflect the originals’ condition. This paper
firstly outlines the task of copying original documents by analyzing official documents, and describes key points
to consider when using copied materials.
The provenance of some of the documents from the HIROHASHI and HINO family collections also appears to be
confusing. This paper therefore attempts to trace the history of the organization and management of these
documents by comparing them to published inventory and catalogued information that remains in official
documents and using labels attached to the documents themselves. Then the paper also examines the correct
provenance of the documents and the cause of this confusion.
