Background and Contents

The work is based on genealogies gathered for the compilation of the Dai Nihon Shi by the Mito domain, which were reorganized with the Sonpi Bunmyaku and other earlier works. It centers on the imperial princely houses and the Fujiwara, Sugawara, Ki, Taira and Minamoto lineages, and also includes daimyo, major shogunal retainers, court nobles and Shinto priestly houses, bringing their lines down to the end of the Edo period. In total it records 777 houses under 60 clan names, including the names of children. For each house, an abridged chart is followed by a detailed main genealogy in which variant accounts are noted within the text.

Characteristics

The work contains lines after the Kansei era that are found in few other compilations. Because it reproduces its sources faithfully, connections that families asserted between their lines and well-known genealogies appear as they were submitted.

Editions

A printed edition supervised by Hōgetsu Keigo and Iwasawa Yoshihiko was published by Meicho Shuppan in 18 volumes (1973–1977), followed by a new edition in 33 volumes (1990–1999; 30 volumes plus 3 supplementary volumes, with indexes of clan names, death years, personal names, and Buddhist names and titles).

Notes for Researchers

Where an entry gives variant accounts, record which account you are citing. Compare each line with other genealogies, temple records and family documents.
