I believe that is his ancient dragon or some form of it, it is one square. I translated the japanese on the page, and it seem to be set for a november release.
This book inludes 19 diagrams, 228 page and 4 color pages.
The diagram instructions are in both Japanese and English.
I wonder these 19 diagrams are new one or just things that had been published in Tanteidan?
Probably a bit of both.
Although even the diagrams that have been previously published will probably undergo some work! (corrections, translations, expansions, etc.)
I don't have concrete information, so this is based on the previous books by origamihouse.
looking forward to seeing what this book will have inside. I cant say I have folded much of Kamiya models but The ones Ive seen around the web are all nice.
