First off I want to address some of the more disparaging comments about this book. People don't seem to realize that the author of this book is Japanese, and the book was written in Japanese, for Japanese people. It has been translated, there are nuances and meanings that are lost both literally in translation, and culturally. 
 The "talking shirts and feeling dishes" and "woo-woo" aspects of the book are in fact examples of animism and animism is a large part of Shinto beliefs. Shinto is practiced by 80% of Japan (thanks wikipedia). These are not the crazy and insane ideas of one woman who is off her rocker. So stop with the Western-centric critique of what is actually an ancient belief system that you've encountered for the first time. 
 I love my house. In a few weeks I will have a tattoo of my home. I dream about my house. I am hard pressed to remember any significant events of my childhood, but can draw accurate floor plans of any building I was in longer than an hour. My first memory is a critique of the preschool's carpeting choice. My childhood artwork is a collection of floor plans and collages of vegetable gardens. I was the kind of child that apologized to doors for slamming them. 
 This house is where I put my time, energy, and money. It only makes sense that every single item in the house is afforded the same respect and decision making that goes into baseboard selection and flooring choices. 
 tldr; 
 The actual book is wonderful. There are the usual "decluttering" suggestions but really it is about the importance of loving your home and being loved by it. Before I read this book, I was really just concerned with the structural aspects of a home and the overall impression that it left. Now I have broadened my gaze to include the individual items within it.
