I've had this book a few years now and I always keep it at hand to inspire me, it is well written, has good practical advice along with clear illustrations and wonderful photographs showing both established Japanese gardens and Western gardens in the Japanese style, there's even a few pages at the end describing various plants ,trees and shrubs that go well with this style.
If you're planning a Japanese garden - get it, or even if you just like to peruse beautiful books with inspiring pics - get it, you will love it.
