“Studies on Matrilineal Systems” by Itsue Takamure, Kodansha, 1954 (with slipcase) A groundbreaking work that demonstrated the existence of matrilineal systems in Japan. This, the author's first work in women's history research, took over seven years to complete, starting with a single volume of "Kojikiden." Simultaneously, it marked the birth of the first scientific women's history in Japan, correcting the male-centric historical view. Based on the collection of all genealogical records of clans recorded in the "Shinsen Shojiroku" and "Shojiroku," this book is researched by dividing them into multiple ancestors, multiple family names, various family names, and bestowed family names, uncovering the fact of matrilineal remnants underlying ancient genealogies. Furthermore, it explores how the customs of matrilineal remnants shaped nation-building, clan-building, and be-building, and how they peacefully achieved central control of the state. It was a result of women's history, obtained by waiting for Itsue Takamure, who re-read and reconstructed genealogies with liberated eyes under the spell of patriarchy.
