幕末期大村藩における剣術流派改変の経緯に関する研究：嘉永 7(1854)年の斎藤歓之助の招聘を中心に

抄録

The purpose of this study is to clarify the transformation that occurred in a school (ryuha) of swordsmanship in the domain of Ohmura, Nagasaki, at the end of the Tokugawa period in Japan, focusing particularly on the invitation extended to Saito Kannosuke, one of the leading instructors in the Shinto Munen-ryu (school of swordsmanship), in 1854. This paper was based mainly based on two historical materials: Shugyo-chu Shohan Houmei-roku (1849) and Kuyo Jitsuroku (1849-1855). Ohmura Sumihiro, the 12th domanial lord, and Egashira Kandayu, his chief retainer, were tacitly interested in the utility of swordsmanship in Ohmura, and actively proposed the transformation of a school of swordsmanship. In 1854, they invited Kannosuke to act as the swordsmanship instructor. Kannosuke was the third son of Saito Yakuro, a famous instructor of the Shinto Munen-ryu, who had established and managed the Rempeikan, a swordsmanship school (dojo) in Edo. Saito Yakuro's eldest son, Shintaro, had embarked on a journey throughout the domains of Japan in order to train and practice against other warriors there. These training and practice were known as kaikoku-shugyo. Shugyo-chu Shohan Houmei-roku indicates that Shintaro visited many feudal domains, including Ohmura. Ohmura Sumihiro and Egashira Kandayu then became interested in the technique of the Shinto Munen-ryu, which was taught at the Rempeikan, because they considered it to be useful for actual fighting. Afterwards, they succeeded in inviting Kannosuke in 1854, and he became the instructor employed by the domain of Ohmura. His duty was to promote the training of the Shinto Munen-ryu with warriors in Ohmura. In 1855, the Itto-ryu and Shinkage-ryu instructors of swordsmanship were dismissed and forced to stop their teaching. According to Kuyo Jitsuroku, this transformation from the Itto-ryu and the Shinkage-ryu to the Shinto Munen-ryu occurred over a period of six years (from 1849 to 1855). It was brought about to achieve the political ambitions of Ohmura Sumihiro and Egashira Kandayu.
