Various KARAKURI Works have been made in Hakone & Odawara region for long years. We investigated, studied and introduced them in this book. Over 400 works appears in this book. For example, Secret Boxes, Interlocking Boxes, various Tabacco Trick, and others. The history and the background are also introduced. We think it's a first overall handbook about KARAKURI Works in this region. //General editor: Sojun Iwasaki
