Here is info from amazon website:
Written in 1915 this 297 page masterpiece is a treatise on the gentle art of Judo. Written by two of Kano's top assitants Sakujiro Yokoyama and Eisuke Oshima it takes you from the beginning to the senior levels. You will learn throws, falls, locks and takedowns and so much more you will not believe it. Kyohan means the Master Text and this is just that the Master Text of Japanese Judo.
I read it slowly, and I did not the finished reading.
There is a lot of interesting information for me. But I am not able give any general review of this book. But I noted one point. There is lot of historical photos of nage waza (Nagenokata) and text explanation of them. Lot of throwing techniques have different form as we know now.
Uranage - Tori position is beside/almost behind Uke before throwing
Hizaguruma - Tori position is beside Uke, Tori blocks the knee from the side, Tori attacks Ukes forward leg (knee)
Taiotoshi - Tori not turns with back to the Uke - there is very long distance - it looks like todays variation of Sumiotoshi
Seoiotoshi - Tori during Kake holds Ukes sleeve and judogi near Ukes obi /or obi directly
Interesting book, may be there are some judo waza roots. There are parts about judo philosophy, principles, ukemi, kuzushi, nage waza, newaza, short target description of atemi waza - advices...
