While researching my first book, The Truth of the Calm Spirit, I became intrigued by the late Edo period Kōbusho, the martial academy of the Tokugawa that several prominent Jikishinkage-ryū swordsmen taught at. My research wound up growing to become a substantial part of this site and I have now made the content available as a companion volume.
From the Kōbusho to the Butokukai: Swordsmanship in Transition (opens in a new tab), Inner Dharma, 2026. 360 pages. The late Edo period Kōbusho, the martial academy of the Tokugawa, its swordsmen and their styles, and the institutions that followed it into the modern era.1
The work covers over 20 traditions and 45 practitioners from this time period.
In this work, I examine details of many late Edo practitioners of Jikishinkage-ryū, the bakumatsu Kōbusho many of them taught at, and important traditions that had lasting impact as Japan modernized, including important 19th and 20th century Japanese martial figures.
The Kōbusho itself ran roughly a decade. Preparations began in 1854 (Ansei 1) under the rōjū Abe Masahiro after Perry; it was formally opened as the Kōbusho in the 4th month of 1856 (Ansei 3) at Tsukiji Teppōzu, with master-instructors and kyōju-kata appointed in swordsmanship, spearmanship and gunnery, and with archery, jūjutsu and swimming also being taught. Kōbusho trainees were selected from skilled martial artists drawn from the hatamoto, gokenin, and the domains.
A selection of the practitioners and the schools I discuss in the book can be read here: selected kenshi and selected ryūha. The records for all of them are also available on GitHub as the kobudo-register (opens in a new tab), for ease of access and search, instead of maintaining complete indices here.

From Ming to Meiji: The Declining Status of Chinese Influence in Japanese martial culture from 1600-1900
One thread that affects multiple articles here, whether on kobudō or Japanese religion, is the early Edo importance of Ming Dynasty culture in Japan as being desirable as an influence and the mid-to-late Edo scorn for Qing Dynasty China. This is only amplified in Meiji and beyond.

End Notes
-
These volumes attempt to be precise but are not academic histories. Instead they are close readings of historical sources. In doing so, we relate the statements made about many older martial traditions by their witnesses and practitioners, but each surviving faction or group will have their own in-tradition orthodoxy ↩
