In recent years, there has been extensive publication of reprints of historical records pertaining to Modern-Period temples. They are published in various forms, such as as supplementary materials for the official history of local communities and reports of the study of old manuscripts carried out by groups of citizens and scholars. This paper proposes an investigation of how to utilize these book-format historical materials with such titles as ‘daily record’ and ‘diary.’ As is well known, previous studies have limited their scope either to one Buddhist sect or one temple. And although the shortcomings of such a practice have been pointed out, there do not seem to be any deviations from this practice. It should be made clear that these materials contain not only the records of annual events and private life but also those of an official nature pertaining to the Government, Imperial Court and Head Temple. As such, it is proposed that they may be used to provide a synchronic record of Modern Period Japanese history.
