Sasaki has a very different view of what minimalism is.  I found this book to be calming and interesting as far as philosophy is concerned, but a bit different when compared to other books of this type. 

This book is not: a manual on how to declutter.
What this book is: minimalism from a Japanese perspective, a philosophy. This book definitely comes off as a bit privileged (a store is a storage system) and minimalism can often be construed to be a classist mess. 

Overall, I already understand minimalist philosophy (focus on others, time, essentials, etc), but for someone starting out this book might be helpful for the journey. Know that his minimalist lifestyle might be inaccessible for you, and that's ok. There are plenty of others who live life with the essentials who own a TV. 

Tip: Reading the book is probably more helpful than listening to the audiobook (which I did) since it's a bit rambly.
