Kashima-shinden Jiki Shinkage-ryū (直心影流) is an important line of Shinkage-ryū. My earlier writing on the art, from 2017–2025, is now available as a book:
Inner Dharma, 2025 — paperback (opens in a new tab) · about the book (opens in a new tab)*
It details the technical composition of its kata (drawing on mokuroku held at Waseda University) and some of the inner principles by which it is organized, with attention to the Daoist and esoteric Buddhist currents that run broadly through Shinkage-ryū.
Please consider purchasing a copy to help support the maintenance of this site.
