This book presents an excellent detailed view of the entire restoration process of the picture hall which is part of Yakushiji temple. I have been marvelled at the bracket (tou-kung) structures in ancient Chinese and Japanese temples but I was not able to find much information about them anywhere. This book not only describes in detail how the bracket system holds the weight of the roof, but also how they are constructed, with detail photos and diagrams of many mortise/tenon joints.
In short, it is just an incredible book that gives you insights into how those Japanese temples were built, without a single piece of nail that holds them together, but yet lasted for centuries.
