One way to learn about the elements of Japanese gardens is to attend regional events or biennial conferences sponsored by the North American Japanese Garden Association.
Such events combine workshops with local experts and tours of nearby gardens for a full experience.
I’m still catching up on many gardens visited and not yet posted. Shofuso Japanese House and Garden in Philadelphia, Pennsylvania was host to this regional event in 2013 concentrating on water features.
