I've been doing a lot of reading on this subject and I choose this book as the best for Japanese garden novices. Chan doesn't overwhelm the reader by parsing schools of Japanese thought or reciting thousands of years of history. This topic could make an enthusiastic reader disappear down a rabbit-hole for several years, but if you are looking for an overview, this is a tidy one.
These designs are suited to a larger scale plot rather than the average back yard garden (check out The Japanese Tea Garden). An extensive plant list is included.
