The Japanese books written by Tadashi Kanzawa have been translated into English.
Kanzawa was featured on the History Channel as a "Stan Lee's Superhuman" for his abilities to put various animals to sleep using "ki".
The books were mostly translated by a Neurology/Physiology graduate Nimish Pratha
and are currently being sent to people for free for a promotion.

The books are mostly centered around healing. His abilities to put animals to sleep seem to be connected with healing the animals through Kiryo or "nerve transmission exchange" and causing them to relax and feel un-threatened.
