This fascinating book here in its complete and unabridged form makes a worthy addition to the bookshelf of all those interested in this craft. This volume presents in its entirety, the kano system of Jui-jitsu , devised by proffesor Jiguro Kano with the additions thereto that have been made by those famous jiu-jitsians, Hoshino and Tsutsumi. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive.
