I now complete the series with the "Nihon-shinshinto-shi", the history of the shinshinto era of Japanese swords, starting from Suishinshi Masahide s initiation of a new trend around An ei (1772-1781) to the ban on swords issued by the Meiji government in 1876. As with the "Nihon-koto-shi" and the "Nihon-shinto-shi", the reader should be able to grasp a coherent picture of the backgrounds and scholastic activities around the Japanese sword at the end of the feudal era. Finally, the time scale must not be overlooked: The "Nihon-koto-shi" had to deal with roughly 800 years, from the Nara to the end of the Muromachi period, and the "Nihon-shinto-shi" comprised "just" about 200 years, whereas the shinshinto era lasted only about a century.
