There are also the large park type Japanese gardens - called the 'Stroll gardens' which are literally gardens for strolling in.
Then there are the small court yard gardens which have their origins in the Tea Ceremony.
As with any art form, Japanese gardening is alive and well. The art is practiced all over the world and even in Japan, it is constantly evolving.
