Hitachi Province appears in Miyamoto Musashi’s account as the home of the Kashima and Katori shrines, whose attendants taught strategic schools attributed to divine instruction. Its significance here is intellectual rather than scenic: the province anchors a recognizable tradition that Musashi uses to distinguish prevailing sword instruction from his broader conception of strategy.

Shrine Traditions and Strategy

Musashi describes the attendants of the Kashima and Katori shrines in Hitachi Province as having received instruction from the gods and established schools on that basis. They then traveled from place to place, teaching men. In his account, this activity represents the recent meaning of strategy: instruction associated with particular schools and with the practice of sword-fencing.

Musashi’s Critique

The reference forms part of a contrast between specialized sword instruction and strategy understood as a wider discipline. Musashi acknowledges that shrine-associated teachers had established schools and carried their teaching beyond the province, but argues that the true value of sword-fencing cannot be confined to technique. Strategy, in his view, had once belonged among beneficial arts and practices, rather than being limited to swordsmanship.

That distinction is central to the book’s larger argument. Its five books address different aspects of the Way, including the Ground, Water, Fire, Wind, and Void; the Wind book examines other schools and traditions so that the reader can recognize their divergences from the Way Musashi advocates. Hitachi Province thus enters the text as a point of origin for a tradition under examination, not as a place described for its landscape or political history.

Place in the Book’s Wider Framework

Musashi’s own account is framed by a different named location: in 1645, at the age of sixty, he says he climbed Mount Iwato in Higo Province to pay homage to heaven, pray to Kwannon, and kneel before Buddha while preparing to explain his strategy in writing. He also states that he did not rely on Buddhist law, Confucian teachings, old war chronicles, or tactical books to set out the spirit of his school. The contrast is not a detailed account of competing religious doctrines; rather, it situates his strategic claims alongside religious language while presenting his written Way as its own inquiry.

The book’s closing treatment of the Void further clarifies the breadth of that inquiry. Musashi warns that what a person fails to understand is not thereby the true Void; mistaking incomprehension for it is bewilderment. The Way of strategy, he says, follows nature, while the Void is approached through knowing what exists and thereby recognizing what does not. In this overall structure, Hitachi Province’s shrine schools serve as one example of the traditions the book considers, while the work’s central ambition is to define strategy beyond the boundaries of any single school’s sword technique.
