Jay Gluck may just have been the first Westerner to write about ninjutsu, with a chapter on the emergence of modern shinobi schools in Japan in his 1962 book, ” Zen Combat”.
It predates the first articles by Arthur Adams in Black Belt, and the publication of You Only Live Twice. It isn’t a cover feature during the boom, isn’t a lead piece designed to sell copies of anything, so it has a raw honesty.
Maybe too raw — Gluck didn’t debunk ninja history, but he surely had no use for the 1960s Japanese ninja boom nor any of the modern practitioners of what he called “dirty weapon” martial arts.
This is an essential read and a little-known chapter of ninjutsu’s exposure in the West.
