Books worth owning
While it is true, Japanese gardening knowledge has seldom been transferred through books, I believe there are many worth reading, especially for the inspiration. I will mention some with the hope that others will share their favorite titles and why they found them useful.
*Japanese Gardens by Gunter Nitschke (theory and history)
*Secret Teachings in the Art of Japanese Gardens by David Slawson (design and some methodology)
*Japanese Garden Design by Marc Keane (some basics and history)
*Sakuteiki translation by Takei and Keane (simplified exerpts from an ancient Japanese gardening text)
And here's one that holds the spirit of Kyoto for me, although not much on Japanese Gardening technique; The Art of Setting Stones by Marc Keane. I often give this one as a gift to friends.
