The only book in English by Seigo Okamoto - student of Kodo Horikawa and founder of Roppokai Aikijujutsu.
Language: English & Japanese
This is a very fine book. It gives a thorough introduction to the many and varied waza of the Daito Ryu Aikijujutsu. The hardcover book had a good sized font, so reading it did not strain the eyes, and the pictures were a good size, and were easy to follow along with. I highly recommend this work to any who are training in grappling skills, and wish to up their game.
Daito-Ryu Aiki Jujutsu by Seigo Okamoto is an outstanding text on Roppokai Daito-Ryu. Roppokai Daito-Ryu is derived from the teachings of Kodo Horikawa, a direct student of Sokaku Takeda. The information provided by Okamoto regarding solo and paired exercises in the Basic Skills chapter is worth the price of the book. The basic exercises are clearly illustrated and described. The book also provides similarly detailed illustrated and described applied techniques for a wide variety of attacks. Daito-Ryu Aikijujutsu by Okamoto is highly recommended for anyone interested in understanding aiki.
