Having a copy of the book in hand, I can say it is well worth it.
The book opens with a overview of the special attack forces, including the origins, history, formation, training, and customs. This moves into details on kamikaze operations in the various Pacific theaters. A list of IJA and IJN units flying suicide missions is included along with the aircraft they flew.
So, if you had a interest in the general history of kamikaze and didn't need info on other nations (ala "Suicide Squads"), this should fill the bill.
A brief bit on shimpu aircraft is given before the book moves into specific suicide aircraft of the IJA and IJN (the link to the index was given by Ryusuke, so, one can see the types discussed).
Fans of the Green Arrow book on IJA and IJN x-planes will be happy to see the Jinryu discussed at length and with photos, as Ryusuke pointed out. This makes the book a must have alone. And, thanks for the tip, Ryusuku, but, I'll stick with Shinryu since my own book discusses the Shinryu II and only gives a overview of the Jinryu as a lead-in to the interceptor design. Asides, since both names are identical in meaning ("Divine Dragon"), using Shinryu for the interceptor, as used in a number of sources, should prevent confusion with the glider. ;D
A number of missile projects are discussed at length, including ones many of us know about (I-Go series, for example) but there is a wealth of photos that you don't often see in other books. For those that may have Akira Sahara's book, now you have translations to some of the missile and jet projects he mentioned in his Japanese text.
The real nice part is the back of the book that has 24 pages of color profiles of the aircraft and missiles discussed in the text.
So, all in all, a most excellent book and a fine addition to one's shelf!
;D
EDIT: One thing I left out is the liberal scale drawings of the various aircraft and missiles. Just the ticket for modelers looking to kit bash.
