Warrior rule in Japan is a compilation of essays by well-known authors on history of Japan: Jeffrey P. Mass, Ishii Susumi, John Whitney Hall and Harold Bolitho. This is a serious academic book on history of institutional development of Bakufu (the warrior government, or, as it is widely known, the Shogunate) in Japan from the times of Minamoto Yoritomo through Tokugawa Bakufu). In contrast to books by, for example Steven Turnbull, who wrote extensively on military strategies, tactics, campaigns and concentrated among other things on personalities of samurai leaders, this author goes into the in-depth analysis of the development of Bakufu as an institution and describes governance of Japanese society, gives some insight into economic and judicial powers of its branches.
"Warrior rule" is a serious reading for a serious scholar. Due to abundance of Japanese terms, it is not easy to read. However, without getting an exposure to the subject of this book, it is not possible to understand, what really stood behind many military campaigns and moves famous people of those turbulent times and feel the atmosphere of samurai age. The life of famous daimyo was not 100 per cent war, but also administration, politics, influence, economics, rituals, law and justice.
In addition, Harold Bolitho provides a general outline of the concept of Han, or local government, or the government of a daimyo, his area of administration and source of power and structure of loyalties. One learns here concepts of local samurai, fudai (or hereditary retainers, although this concept is quite described by other authors as well), shugo, jito and other concepts necessary to learn history of this legendary age.
